Switch State
Description
1
Closed
Verify is enabled and the verify time is 5 seconds
2
Open
3
Open
4
Closed Latching mode (LEDs stay on until reset)
5
Open
Used for silane only. UVIR must detect both UV and IR
to declare a fire. This is done to reduce false detections,
since Silane systems are sited outdoors. These detectors
are labeled with "Configured for Silane".
5
Closed
Used for all other gases. The detector will declare a fire
if UV and IR are present, but can declare a fire with only
the presence of IR.
6
Open
Testing of the UV sensor occurs every 30 minutes.
7
Closed The UVIR is set to detect a 1 square foot gasoline fire at
a distance of 60 feet.

SS4-A/-A2 Detector System Relays
1.5.1
Fault Relay:
The fault relay checks for normal operation of the UV/IR Detector. The detector
issues a fault condition by de-energizing its Fault Relay and the controller will show a UV/IR
Fault alarm on its screen. If there is a fault, the detector will illuminate one LED to visually
indicate the fault. The list of Detector Faults include temperature fault, excessive input voltage
fault, no power fault, detector fault, relay fault, self-checking fault, and analog ‘0’ current. The
LED will not light if the fault is “no power”. If the fault condition is eliminated, the detector
will return to normal operation and the LEDs will return to blinking every 10 seconds. Faults
requiring factory recertification will be indicated with the LEDs rapidly blinking.
