2.12Relay Parameters

Relays provide dry contact (normally open or normally closed) outputs for LED annunciation and other applications as well as wet voltage outputs

(12 VDC on or off) for basic alarm system functions (such as Bell Output or Reset Sensors). The applications are endless, but mainly, relays enhance a system’s capacity to perform output functions.

Panel-Wide Relays: These relays provide an output related to a panel-wide indication. For annunciation, these relays can indicate system- wide troubles for power and phone. They also provide an overall control panel summary of alarms, troubles, and supervisory conditions.

Area Relays: These relays provide an output by the area to which the relay is assigned. An area can have its own bell and sensor reset indications. Relays can also indicate the area armed state and whether any off-normal conditions, such as a Force Arm, occurred.

On Board Relays: Three on-board 12 VDC voltage outputs provide power when activated on the control panel. These outputs are programmed at the factory as Relays A, B, and C. Typically, Relay A (Terminal 6) is used for the bell, Relay B (Terminal 7) is used for an alternate alarm output (such as another bell), and Relay C (Terminal 8) is used for Sensor Reset (Relays B and C require the optional D136 Relays).

Off-Board Relays: The D9412GV3 can also control 128 (64 for the D7412GV3) dry-contact form C relays when up to sixteen optional D8129 OctoRelay Modules are installed. These relays are used for Area Relay, Panel-Wide Relay, and Individual Point Fault Relays.

Relay Reports: When relay activity is reported to the receiver (refer to Section 2.3 Routing on page 17), on-board relays are reported as follows:

A = 253 B = 254 C = 255

The others report as 001 to 128. The Relay Report is RELAY SET RELAY # rrr when the relay is turned on and RELAY RESET RELAY # rrr when the relay is turned off. Relay Reports are also printed on the local printer and stored in the control panel memory log.

Controlling Relays: Relays can activate depending upon conditions that exist with the control panel. In addition, the user can control relays by using the Change Relay? function, Relay On/Relay Off skeds, and the Remote Account Manager.

Before programming your relays:

Do not use the CHANGE RELAYS? function to toggle relays reserved for special functions. Special function relays are Area and Panel Wide Relay functions as well as relays assigned to CC Enter Key Relay and P## Relay Response Type.

Relay C is always on. Assigning any other relay (1 to 128, A or B) deactivates Relay C so this output can be used for other functions. When Relay C is programmed for A# Rest Sensors, power is always supplied from Terminal 8 of the control panel.

Relay Restoration: The status of relays after programming or resetting the control panel might restore automatically or require manual restoration. All relays are turned off after the control panel resets. The control panel checks certain relay functions every minute and resumes the correct state after the reset. Other relays must be manually set to the correct state using the Change Relay Function (COMMAND 54).

Relay Follows Point: Relays can also be used to activate when a point programmed for P## Relay Response Type (refer to P## Relay Response Type on page 96) is off-normal or in an alarm condition.
