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 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. 

  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).
