On-Board Relays (Conventional)

NOTE: Figure 4.47 uses UL listed door holder Model 1400 from Door Control International as an example.
Constant Power
Use constant power for applications that require a constant auxiliary power source. Power is always present at Constant circuits.
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, the power automat-
ically becomes disconnected from the terminals for 30 seconds, then re-applied.
Sounder Sync Power
The Sounder Sync Power continuously outputs the System Sensor synchronization pattern and is intended for use with B200S/IV sounder
bases.
4.14 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 Resis-
tive.
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.
4.14.1 Common Trouble Relay
The control panel has a dedicated Form C trouble relay built into the 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.
4.14.2 Programmable Relays
The control panel has two Form C programmable relays built into the terminals labeled, RELAY 1 or RELAY 2. Each relay provides a nor-
mally 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 4.48 for the location of the relay terminals.
2. Configure the relay through programming (see Section 8.2).
