*Temp 4 pattern is repeated pattern of four short indications fol-
lowed by a five second pause.
When the detector has been in alarm for 30 minutes the alarm
signal will be given once every minute.
If ambient conditions return to normal, the detector will self-re-
store out of alarm and into Normal (standby) mode.
Hush feature: 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 au-
dible alarm will sound. The hush facility will not operate at levels
above 350 ppm (parts per million) carbon monoxide.
Trouble feature: When the sensor supervision is in a trouble con-
dition (such as a sensor that has been tampered with), the detec-
tor will send a trouble signal to the panel. The detector must then
be replaced.
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
six years from the date of manufacture. Refer to Detector Replace-
ment 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.
