Alarm Test: Will send alarm signal to panel.
Hush feature/Alarm Silence: If required, the audible alarm can be silenced
for 5 minutes by pushing the button marked “Test/Hush”. The red alarm light
will continue to flash in temp-4 pattern. If carbon monoxide is still present
after the 5 minute hush period, the audible alarm will sound. The hush facility
will not operate at levels above 350 ppm (parts per million) carbon monoxide.
RealTest® Alarm Silence: Alarm will automatically silence after about 20 sec
-
onds of alarm from spraying canned CO into the detector. Alarm Reset: Alarm
automatically resets after CO has cleared from the sensor.
Trouble feature: When the sensor supervision is in a trouble condition (e.g.
such as a sensor that has been tampered with, or the cell itself has prema-
turely dried out due to environmental conditions, etc.), the detector will send
a trouble signal to the panel. The detector must then be replaced. The green
LED turns off and the red LED blinks every minute when the detector is in
trouble.
End of Life Timer feature: When the detector has reached the end of its life,
the trouble contact will open. This indicates that the CO sensor inside the
detector has passed the end of its life and must be replaced. This detector’s
lifespan is approximately ten years from the date of manufacture. The green
LED turns off when the detector is in trouble. Periodically check the “Replace
by” sticker located under the detector cover. The detector must be replaced by
this date. Refer to Detector Replacement on page 3.
Per UL 2075, it is mandatory that a trouble signal be sent to the panel
upon CO cell trouble or cell end of life. Refer to Figure 4 for wiring of the
trouble relay.
