Alarm Relay

One Form-C dry alarm contact is provided in the basic panel for controlling
supplementary devices. It is rated 2 amps at 30 VDC and 0.5 amps at 30 VAC
(resistive), and is non-silenceable when an alarm occurs. See below for terminal
location.

Trouble Relay

One Form-C dry trouble contact is provided in the basic panel for controlling
supplementary devices. It is rated 2 amps at 30 VDC and 0.5 amps at 30 VAC
(resistive), and will silence when trouble condition is cleared. See below for terminal
location.

Note: The alarm and trouble Form-C dry contact relays must be power limited relays. They must be wired
from one of the 24V power limited terminals as shown in the figure below or a comparable UL listed power
limited power supply.

This output is not suitable
for powering devices
requiring filtered DC power.

The combined current draws from the Resettable
and Non-resettable outputs cannot exceed 200 mA.

RMS-Regulated Power
24 VDC power for inductive-
type devices such as door
holders can be connected to TB1
terminals 1 (+) and 2(-).

4-Wire Smoke Detector Power
24 VDC filtered, resettable power
for 4-wire smoke detectors can be
obtained from TB1 Terminals 3(+)
and 4(-).

Non-resettable Power
24 VDC filtered, nonresettable
power can be drawn from TB2
Terminals 1 (+) and 2(-).
