Alarm Relay Circuit
One Form-C dry contact alarm relay is provided in the basic panel for controlling supplementary devices.
Contacts are rated 2 amps at 30 VDC and 0.5 amps at 30 VAC (resistive) and are non-silenceable when
an alarm occurs.

Trouble Relay Circuit
One Form-C dry contact trouble relay 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 restore to normal when the trouble
condition is cleared.

condition is cleared.
Note: Power connected to these relay contacts must come from a power-limited supply. Power may be obtained from
TB1 Terminals 24VU or 24VR and TB2 Terminals 24VNR, or a UL-listed power-limited power supply.

RMS-Regulated Power -
24 VDC power for inductive-type
devices such as door holders can
be connected to these terminals.
This output is not suitable for
powering devices requiring
filtered DC power.

Resettable Power -
24 VDC filtered, resettable power for four-wire smoke
detectors can be obtained from these terminals.
The combined current draws from the Resettable and
Nonresettable outputs cannot exceed 200 mA.
