Central Unit for Alarm System (CUAS) Evaluation Board
Introduction
The Central Unit for Alarm System (CUAS) Evaluation Board provides a complete reference system addressing the low- to middle-end security sectors. The tool is ready, from hardware and software point of view, for the development of a complete alarm platform based on a bus network. Thanks to a PC graphical user interface (GUI), it is also possible to easily set up all control parameters (in addition to a control/programming panel connected through the bus). The entire system consists of four boards: Central Unit (CU) board, Control Module (CM) board, Power Supply (PS) board and the PC interface board. There is also PC GUI software that enables the user to easily configure all CU parameters and to execute certain system tests. It is possible to expand the system by means of input/output expansion boards, a GSM board (a connector is available on the CU Board) for managing the CU using a cell phone and other modules using radio-frequency identification (RFID), smartcard or keyboard devices connected through the bus.

System description
An Alarm System consists of a Central Unit (CU) that manages a certain number of inputs (typically connected to sensors and detectors, called zones), outputs (connected devices such as sirens, indicators, etc.) and other devices (i.e. RFID keys, Smartcards, Expansion Modules, GSM, Keyboards, RF module, etc.) connected to the communication bus for system management and configuration as shown in Figure 1. The system is controlled using up to 8 Control Modules that regulate system installation, parameter configuration and switching on/off the CU and partitions. Each zone of an alarm system can be configured, logically regrouped, separately processed and associated to a group of outputs in a different way. The outputs are also configurable in terms of timing, working mode and normal status (High or Low). This CU is composed of 8 zones directly hard-wired to the CU board. It is possible to expand the number of zones by connecting one or more I/O Expansion modules through the bus. Seven hardwired outputs are available:

Four outputs are separately driven by a solid state relay (SSR - VN340SP) and can deliver up to 1A for each output. These outputs are normally used for connecting sirens and other external devices (auxiliary outputs). Two outputs are transistorized and typically used for indicating the system status (alarm condition, CU status, etc.). One output is a micro relay for general purpose uses such as connecting a video recorder, external GSM, etc.

System features Special inputs are also available on the CU board such as the Tamper line used to indicate any tampering with the system. This line is normally connected in series with the Tamper inputs of each sensor or device connected to the CU. A fire/smoke line is also present on the CU board and is used to continuously monitor all fire or smoke sensors; immediately signaling any warnings depending on the line configuration, but independently of the CU status. The system works using an RS-485 communication bus. This is a 4-wire bus (2 wires for power, 2 for communication) that complies with RS-485 standards and guarantees good noise immunity. The communication algorithm provides an encrypted protocol that prevents information sniffing on the communication bus. Thanks to this bus, system modules can be placed far away from the CU using a reduced number of wires. This configuration reduces setup time, wiring and the wiring costs. Figure 1. System overview

Getting started
In order to correctly operate your alarm system using the CUAS Evaluation Board, follow the steps listed below. (Refer to Figure 2, Figure 3, Figure 4 and Figure 5.) 1. 2. 3. 4. 5. 6. 7. 8. Connect the Power Supply board to the power supply connector on the Central Unit (J2). Connect the Control Module board to the Bus connector on the CU (CM BUS - J6) using connector J11 or J13. (Ensure that the keyboard is connected to connector J16). Connect the PC interface board to the Bus by the connector J36 either on the connector COMM BUS J5 of the CU or the connectors J13 or J14 of the CM. Connect the PC interface board to the PC serial port through an RS-232 serial connector (not a null-modem). Connect the mains power to Mains connector on the Power Supply board. Power the PS with the mains. Connect the battery on the Power Supply board. Push the Initial Setting push button for at least 5 seconds. After a brief delay, the CM screen will display the date, time and CU status.

Note:

Perform Steps 3 and 4 only if a PC is required. The following figures show the block diagrams of the CU, CM, PC Interface and the Power Supply boards.

2.1

System parameters
Introduction
System parameters can be configured by using either the Control Module or the PC Interface. Using the PC interface provides the advantage of using a user-friendly graphic interface (GUI) to configure the system parameters off-line. Once the system is configured on its own PC, it is possible to download information to the CU. For safety reasons and in order to avoid any tampering from a different installer, a system installation code is required before entering Parameter Setting mode on the CU.

2.2

Zones
Each zone is balanced, meaning that the CU detects any resistance variations on the input line. A certain resistance value is assigned during the installation and when an imbalance is detected, it is considered as an infraction and processed. In each zone, a resistor can be placed between each zone terminal (i.e. J20 to J24 for the hard-wired zones). In this case, the value of each resistor can be decided by the installer and it is not necessary to set the same value for each zone. Using this feature ensures that any additional resistance values coming from the wiring do not affect system performance. Each zone can be included or excluded from the control flow (i.e. if a sensor is broken the zone in which it is connected can be temporary excluded), and the working mode can be set either as normally closed (NC or balanced) or normally opened (NO or unbalanced). The zone status variation is immediately stored by the CU when detected, but it is processed only once the delay time associated to the zone is elapsed (if any delay is set). Each zone can be logically associated to all the others in OR (as default) or in AND modes. In AND mode, status variations are detected and processed by the CU only if all the zones in AND mode have their status changed too. Each zone can be in AND mode with another zone, but the vice versa is not mandatory. For example, Zone 4 can be in AND mode with Zone 5 (Zone 4 is now seen as Group 4), but Zone 5 is not in AND mode with Zone 4 (Zone 5 is associated to Zone 4 in OR mode). Each zone is protected against negative voltage, over voltage and ESD.

2.3

Outputs
Each output behavior can be configured as "change status" (ON for a certain time followed by an OFF period or vice versa) or "toggle status" (each time an alarm condition occurs, the output status is toggled). One or more outputs can be associated to each zone and can be enabled or disabled from the system. The default level of each output can be configured as high or low. Four outputs are SSR outputs that can supply up to 1A (internally limited) depending on the power supply capacity (connectors J25/J26, J27/J28, J29 and J30). Typically such outputs are dedicated to sirens (self-powered and internal) and for other devices that require power (connectors AUX1 and AUX2). Two outputs (J32) are transistorized general purpose outputs that can be configured for signaling alarm conditions or the CU status.

The last output is a micro relay with the NC, C and NO clean contacts available. The maximum voltage and current applicable to the contacts is 0.4A @ 125VAC and 2A @ 30VDC for resistive load and 0.2A @ 125VAC and 1A @ 30VDC for inductive load.

2.4

Partitions
A partition is a logical group of zones with an assigned name and behavior that can be activated or deactivated by an activation device existing on the system (i.e. keyboard, smartcard, etc.). On each partition, it is possible to associate two or more zones present on the system; a single zone may belong to several different partitions. Zones are associated as inputs or outputs:

An input association means that when the partition is deactivated by a device (i.e. by a smartcard when entering a protected area) ONLY all the zones associated to the Input will be excluded by the control flow. If any of the zones not associated to the deactivated partition is forced, an alarm condition will be detected and processed. An output association means that ONLY the associated zones will be controlled by the CU once the system is activated by a device.

Each partition can be associated to one or more user codes and vice versa. Each time a user enters his code, all the partitions associated to that code can be enabled or disabled even individually.

2.5

Log events
The CU automatically records a certain number of events in the internal E2 memory once they occur. The event log feature enables the owner or the installer (not the users) to view the event history using the appropriate menu feature (or, these events can be downloaded through the PC interface and analyzed). The system can record up to 999 events. If more events occur, the oldest ones are automatically replaced by the newest.

2.6

Options
During the installation it is possible to enter Test mode. Test mode enables the installer to test (by watching the signal level associated to the selected zone) zones installed on the system individually or all together once all the sensors are wired on the CU and the zone balanced. The CU automatically stores the balance values after the command is properly sent by the installer to the CU. In Output Test mode, it is possible to toggle each output level each time the installer presses a key (or when the appropriate command is sent to the CU using the PC GUI). In this way, it is possible to test each device connected to the outputs. A Module Acquisition feature is available from the Option menu. This feature enables the installer to update the communication bus module address table; adding new modules and removing any deleted modules on the system. Once the update is started, the CU starts scanning for modules and stores all the modules that acknowledge the CU interrogation. Of course, this feature is available only at the service level. Once an owner or service password is entered, it is possible to enter the system status menu to display the actual status of each zone and output.

System hardware configuration
Introduction
The hardware configuration greatly depends on the area to protect. The CU is very flexible due to its easy way to program each input and output line. It is possible to configure a more powerful system using bus modules to expand the features. It is possible to manage, for example, two different areas independently or with one or more zones in common; it all depends on how the CU is configured. Using the GSM module, it is possible to know the CU or the zones status, enable or disable the partitions, or perform several actions on the outputs remotely. Thanks to the fully configurable outputs, it is possible to decide which device to connect (sirens, external devices, etc.), the activation time, working mode, etc.

3.2

Sensor connections
The sensors must be connected to the zone terminals (connectors J20 and J21, connectors J23 and J24) as shown in Figure 6. It is possible to connect a balance resistor in series with the sensor switch to detect both line cutting and line short-circuiting. Even the tamper line can be balanced. Moreover, thanks to the autobalance control feature (see Zones Autobalance on page 31), it is possible to place more than one resistor in series with the tamper line (each tamper switch must be connected in series to all the others). This configuration enables a more efficient balance control of the tamper line than when placing only one resistor. Figure 6. Sensor wiring diagram

3.3

Control module connections
Either connectors J11 or J13 can be used to connect the control modules (CM) by wiring the 4 terminals using a twisted and shielded cable. This cable has to be connected to jumper J6 (CM BUS) of the CU. It is possible to connect up to 8 CMs on the bus line in different ways as shown in Figure 7.

Central unit connections
Table 1 describes all the CU main board connectors. The Initial Settings switch is used the first time the system is installed or to completely erase all the setup information. Press this switch for approximately 5 seconds when the CU is completely disabled, to reset all previously programmed parameters (except for the system date and time) with the factory parameters (see Section 4.3: Configuration using the Control Module).

Output connections
Output connections are not strictly predetermined enabling a flexible configuration for your system. Certain outputs are best used for siren connections, while others for general purpose devices depending on the required current and device type. Figure 8 shows a typical siren connection that takes into account different types of both internal and external sirens. Cer tain external sirens require a third terminal (V) in addition to the power supply (also used to charge the backup battery). In this case, connect the siren power terminals to the SIR AAx connectors; the "+" terminal with Clamp 3 and the "-" terminal with Clamp 1 (permanently connected to +13.8VDC), and the terminal V with Clamp 2. Only Clamp 2 is programmable using the CU setup (see Section 5.6.2: Outputs) in either normally high

Outputs AUX 1 and AUX 2 from the solid state relay can be used to connect external devices and are fully programmable. As shown in Figure 9, there are two other fully programmable outputs (transistorized) that include one more option allowing to configure the STS output as a CU status output. The value of the STS output depends on the CU status (enabled/disabled) and the ALM output as an alarm output where the value of the ALM output changes each time there is an alarm condition. Note: In the current version, outputs STS and ALM can be configured as a normal output. The current software version does not manage the alarm and CU status signaling. Figure 9.

Configuring system parameters
Introduction
The system can be configured in one of two ways:

using the PC GUI using the Control Module

The system is configured by entering Setup mode; this is possible only if the Central Unit (CU) is in Idle mode (CU disabled). During the first installation or each time a new module is installed or removed from the system, the connected modules must be registered in the CU memory. When using the PC GUI, the software automatically registers connected modules in the CU memory. When using the Control Module, follow the instructions provided in Section 4.3: Configuration using the Control Module.

4.2

Configuration using the PC GUI
This feature is not implemented in this version.

4.3

Configuration using the Control Module
At first installation, communication with the CM is impossible since no modules are registered in the CU memory. For this reason (or each time a new module is installed or removed from the system), press the Initial Setting button on the CU board for approximately 5 seconds. The CU scans the bus and registers all the modules installed on it. Once this procedure is successfully completed, the CM displays the system date/time and the CU status (OFF) as shown in Figure 10. Figure 10. Central unit connected message

Note:

Pressing the Initial Setting button resets all the system settings on the CU to their factory settings (except for the system date and time).

Password protection
In order to perform any operation, password identification is required. The system is organized with three password security levels. Press any key on the CM keypad to access the password menu. Table 2.
Level Service

Password protection for each access level
Description The service level is dedicated to system installation. All CU parameters are accessible and modifiable and passwords can be setup. The CU cannot be enabled or disabled when accessing this level. This level is normally assigned to the protected ambient owner. Only parameters that do not affect the hardware configuration are accessible (i.e. the zone timing, output association, etc.). The CU cannot be enabled or disabled when accessing this level. This level switches ON/OFF the CU and available partitions. It is impossible to modify or display parameters.

Owner

User

The service and the owner passwords must be different from each other because the CU automatically recognizes the access level by the password. It is possible (but not recommended) to use the same Owner (or Service) password as one of the User passwords. All the User passwords must be different.

Menus

Description
The Zone description is 16 characters long and is displayed on the System Status (Section 5.4: System status) and Log Event (see Section 5.5: Log event) menus. This displays a more significant name rather than a number. To change the description, press ENT, enter the new text and press ENT again to store the new description.

Status
The Status sub-menu adds or removes the selected zone from the control flow. Once disabled, the zone is no longer under control, even if included in an enabled partition. This option is used for disabling the zone if it is not used, if a sensor connected on it is broken (waiting for a replacement) or to temporarily disable the zone without losing any settings. Press ENT to switch between the two possible values (enabled/disabled).

Input time
The input time is delay between the detection of an alarm condition and the triggering of the associated outputs. Normally this time is assigned to zones that protect the area (and the
25/40

Menus

UM0272 path) where the CU insertion device (keyboard, smartcard device, etc.) is installed. The alarm condition is immediately stored, but is processed only once the input time is elapsed. To change the input time, press ENT; the minutes will be changed first and the seconds immediately after. Press ENT to store the new values. If the input time is set to 0 minutes and 0 seconds, the zone will be considered as instantaneous in input. The input time can be set from 00:00 to 59:59 (mm:ss).

Output time
As with the input time, it is possible to associate an output time in order to allow authorized personnel to leave the protected area once enabled the CU. The time is set as described in Input time.

Working mode
The Working mode indicates the way the CU detects an alarm condition. The following Working mode values are possible:

Normally opened: The zone is normally unbalanced from its stored value (see Outputs Test on page 32). Once the zone is balanced, the CU processes the alarm condition (after an input or output time, if set). Normally closed: The zone is normally balanced and an alarm is processed when an unbalanced state is detected. Change: This is a mixed working mode where the CU process an alarm condition each time a different value from the previous one is detected (unbalanced if the zone is balanced and vice versa). Once the alarm is processed, the CU considers the new zone status as the normal one. Press ENT to switch between the different working modes. Beeper signal: This feature triggers a buzzer when an installed control module detects an alarm condition in the zone. Press ENT to switch between enabled/disabled. (Not included in this version.) Filter: The zone filter enables the CU to detect an alarm condition only after a certain time (the counter is reset once the filter time is elapsed). As shown in Figure 20, press ENT to first modify the number of pulses (zone value changes), up to 999 pulses can be programmed, and the time within which the pulses must occur (mmss). (Not included in this version.)

Note:

The Working mode for inputs is always normally closed. The option for changing the Working mode is already implemented but has no effect in this release.

Outp. associated: This function associates one of the installed outputs to the selected zone. Once the zone alarm condition is processed, the corresponding outputs are triggered. Press ENT to display the output associated menu (Figure 21) and the first 8 outputs hardwired on the CU. If more outputs are present on the system by means of one or more IO Expanders, press to display the next group of 8 outputs. Press to scroll through each displayed output. In order to associate the pointed output, press ENT. The symbol displayed after the output number will change from a dot (.) to a plus sign (+). See Chapter 5.6.2 for possible output configurations.

Figure 21. Output associated menu

AND association: This feature allows the installer to logically regroup the selected zone to one or more of the other zones installed on the system. If a zone is in AND mode with another zone, the CU will detect an alarm condition only if all the other zones associated in AND mode detect an alarm condition also. This feature can be useful, for example, in a corridor where two sensors are installed; the alarm condition is processed only if an infraction is detected in one direction but not the other. The AND association menu is similar to the output association menu.

5.6.2

Outputs
The Output settings menu (Figure 22) is used to configure both the outputs hardwired on the CU and those installed by means of the IO Expander present on the system (if installed).

Description
The Output description is 16 characters long and is displayed on the System Status (Section 5.4: System status) and Log Event (see Section 5.5: Log event) menus. This displays a more significant name rather than a number. To change the description, press ENT, enter the new text and press ENT again to store the new description.

Status
The Status sub-menu adds or removes the selected output from the control flow. Once disabled, the output will not be activated by the CU even if associated to a zone where an alarm condition is detected. This option is used for disabling the output if it is not used, if a sensor connected on it is broken (waiting for a replacement) or to temporarily disable the output without losing any settings. Press ENT to switch between the two possible values (enabled/disabled).

Working mode
The Working mode indicates the way the output is managed once enabled and associated to a zone. The possible working mode values are the following:

Change Status: The CU changes the output value during an alarm condition and restores the previous value once the time associated to the output is elapsed. Toggle: The CU toggles the output value each time it detects an alarm condition. In order to switch between the different working modes, press ENT. Default Level: The default level can be normally high (the SSR outputs and the transistorized outputs are at 12 VDC level, the Relay will close the contacts between the C and NA terminals, the Buzzer is normally activated) or normally low (the opposite

Menus condition). In order to switch between the different default levels, press ENT; the output will immediately change its value.

Timing: The output time is the time that the output remains active (the active status depends on the default level setting) when the CU processes an alarm condition. Press ENT to display the menu shown in Figure 23. Press ENT again and the cursor will underline the hour field. Press ENT again to save the Hour value and pass to the minutes field, and finally to the seconds field. The maximum time allowed is 11h 59m 59s.

5.6.3

Partitions
Par tition menus (Figure 24) are used to configure partitions which are logical groups of zones. Each time a partition is activated by an activation code (see Section 5.6.9: Bus modules), all associated zones are controlled by the CU to detect an alarm condition (infraction). Alarm conditions in inactive partitions are ignored and not processed (even when detected) by the CU. Par titions are associated to zones both in input and in output. The input association is the group of zones that will be removed from the control flow of the CU once this partition is disabled by any activation code (normally when entering the protected area). The output association is the group of zones controlled (and processed when an alarm condition is detected) by the CU when leaving the protected area. Figure 24. Partition menus

Installation code
For security reasons, an installation code is required to enter the CU in Setup mode using any programming device (either a Control Module or the PC GUI). The factory value (both for the CU and the CM) for the installation code is 0 0 0000. Changing the installation code from this menu affects both the installation code of the CU of the CM programming the CU. If more than one CM is installed on the system, the old installation code must be changed manually for each module.
