1.4 Overview
1.4.1 Model SS4-A/-A2 Detector
Version SS4-A: There are two (2) LEDs on the Model SS4-A 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-A-2: The operation of this unit is identical to the SS4-A,
except the fire alarm LEDs turn off once the fire threat is eliminated,
without power cycling of the device.
