Overview
1.4.1
Model SS4-AS/-AS2 Detector
Version SS4-AS:
There are two (2) LEDs on the Model SS4-AS Detector that
indicate the state of the Detector. During normal operation both LEDs will blink
every 10 seconds.
If the Detector alarms to a fire, it energizes the Fire relay and turns on both LEDs
in the following sequence. One LED is turned on immediately and the second
LED will rapidly blink for several seconds indicating that the Detector's FirePic
spectra is being permanently stored in the Detector's solid-state memory (FirePic
is the several seconds of Detector spectral data which precedes an alarm event).
Once the FirePic data is stored, the second LED will remain on. For this version,
the fire alarm LEDs turn on and remain on until power to the unit is cycled (turned
off and on again).
If the Detector has a Fault, it de-energizes the Fault relay and turns one (1) LED
on (the LED will not light if the Fault is a “No Power Fault”). If the Fault condition,
such as a “Low Voltage Fault”, is eliminated the Detector will automatically return
to Normal Operation.
NOTE:
Faults caused by excessive input voltage or due to temperatures
outside the operating temperature range require factory re-certification.
Re-certification is required if a Fault is indicated by both LEDs rapidly
blinking (with frequency about 2 Hz.).
Version SS4-AS2:
The operation of this unit is identical to the SS4-AS, except
the fire alarm LEDs turn off once the fire threat is eliminated, without power
cycling of the device.
