4.11.2.2 Constant Power
Use constant power for applications that require a constant auxiliary power source. Power is always present at
Constant circuits.
4.11.2.3 Resettable Power
Resettable power is typically used to power beam detectors, flame detectors and conventional 4-wire smoke
detectors. For circuits selected as Resettable, 27.4 volt power is always present at the terminals unless a system
reset occurs. If a system reset occurs, power is disconnected from the terminals for 30 seconds, then re-applied.
4.11.2.4 Sounder Sync Power
Sounder Sync Power continuously outputs the System Sensor synchronization pattern and is intended for use
with B200S sounder bases.
4.12 On-Board Relays (Conventional)
The control panel has two built-in programmable relays and a built-in trouble relay. All relays are Form C rated
at 2.5 A @ 27.4 VDC Resistive.
Figure 4-32 Location of Conventional Relay Circuits
Note: The N.C. contact is the relay contact that is closed when the panel has power and there are no alarm or
trouble conditions.
4.12.1 Common Trouble Relay
The control panel has a dedicated Form C trouble relay built into terminals labeled TROUBLE. The relay
provides a normally open and a normally closed contact. The trouble relay will deactivate under any trouble
condition. Form C rated at 2.5 A @ 27.4 VDC Resistive.
4.12.2 Programmable Relays
The control panel has two Form C programmable relays built into terminals labeled RELAY 1 or RELAY 2.
Each relay provides a normally open and a normally closed contact.
To install one or two programmable relays, follow these steps.
1. Wire Relay 1 and/or Relay 2 as needed for your application. See Figure 4-32 for the location of the relay ter-
minals.
2. Configure the relay through programming (see section 7.5).
