3. 3 WIRING, FINISH

3.3.1 ALARM RELAY OUTPUT
The Single Pole Single Throw (SPST) relay output can be used for remote
signaling of alarm condition. A form “C” contact rated at 1A is available.
Connect to J4, P1 and P4 (See Section 8.0 for Diagram of J4). This relay
can be used as a dry contact for remote indication or can drive an SRAN
remote annunciator.

3.3.2 OPTIONAL REMOTE ANNUNCIATOR WIRING

Setra SRAN wiring
In the fi gure below, the SRAN remote annunciator connector is at left, and
the SRPM connector is at right:
On J4 of the SRPM, jumper P1 to P2, this will connect the internal
15V supply to the common of the internal alarm relay. Connect P2 to
A1 (Located on Remote Annunciator), this supplies 15V exc. to the
Annunciator for powering the circuit during normal conditions. Connect P3
of J4 to A2 of SRAN J1, this is the 15V power return. Finally connect P4
of SRPM J4 to A3 terminal of SRAN J1, this is the alarm trigger.
When an alarm occurs and after the programmed alarm delay times out
the internal relay will supply 15 V to the Annunciator circuit to actuate the
audible beeper and the red LED.

Non-Setra Remote Annunciator
The SRPM can drive other annunciators that are powered by a 15V sup ply, 50 mA
max current draw., and accept a 15V trigger (wire as above).
