Product Overview
CAUTION!
THIS SMOKE AND CO ALARM IS DESIGNED FOR INDOOR USE ONLY. DO NOT EXPOSE TO RAIN OR
MOISTURE. DO NOT KNOCK OR DROP THE ALARM. DO NOT OPEN OR TAMPER WITH THE ALARM
AS THIS COULD CAUSE MALFUNCTION.
Test & Silence Button
The Test & Silence button is used to test the unit’s electronics and to silence the unit during an alarm.
When testing the alarm weekly, press the test button until you hear a short beep, indicating that the
alarm has entered the test mode.
Note: After a test has begun, the alarm will sound and the LED will fl ash red. This does not
indicate that smoke/CO is present. When the CO concentration is above 300 ppm, the silence
function cannot be enabled.
If you press the test button during an alarm state, the unit will enter the silence mode.
CO silence mode:
Press the test button during an alarm state, the unit will enter the silence mode. If
the CO density still exceeds the alarm threshold within 6 minutes, the unit will enter another alarm state.
Otherwise, the unit will exit from silence mode after 9 minutes.
Note: If the smoke or CO concentration has reached an alarm level, after the silence time has
expired, this unit will continue to alarm until the smoke or CO concentration decreases to a
safe, low level. When the CO concentration is above 300 ppm, the silence function cannot be
enabled.
Alarm Sounder
The alarm will sound when there is smoke or CO present, when testing the alarm, and when there is a
fault.
LED Indicator
The LED indicator will fl ash in conjunction with the alarm sounder. Therefore, it will fl ash during the
following states: when powering on, in standby mode, during smoke or CO alarm states, when exiting
an alarm state, during test mode, when there is low battery, in silence mode, when there is a fault and
when the unit is at the end of its life.
Low Battery
The LED indicator will fl ash yellow together with one beep every 60 seconds.
(If you press the test button when there is low battery, the low battery signal will temporarily cease
for 10 hours; if you press the test button again, the unit will enter the test mode and then the standby
mode.)
