Control Panel Installation

4.13.5.2 Constant Power
Use constant power for applications that require a constant auxiliary power source. Power is
always present at constant circuits.
4.13.5.3 Resettable Power
Resettable power is typically used to power beam detectors, flame detectors and conventional
4-wire smoke detectors. For circuits selected as Resettable, 24 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. See Table A-4 for compatible four wire
smoke detectors.
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 @ 24VDC.
Figure 4-40 Location of Conventional Relay Circuits
4.14.1 Trouble Relay
The control panel has a dedicated Form C trouble relay built in. The relay provides a normally
open and a normally closed contact. The trouble relay will deactivate under any trouble
condition.
Note: The NC contact is the relay contact that is closed when the panel has power and there are no trouble con-
ditions.
4.14.2 Programmable Relays
The control panel has two Form C programmable relays built in. 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 4-40 for the loca-
tion of the relay terminals.
