IF THE CO ALARM SOUNDS:
WHAT TO DO IF NATURAL GAS IS DETECTED:
1. Leave the house immediately, opening doors and windows as you leave.
2. Do not use your telephone or appliances. Do not turn any light switches off or on. Any
spark or flame could ignite the gas.
3. Call 911 and your gas company from a phone that is away from your home.
4. Do not reenter the area until the source of the leak is found and corrected.
If you hear the alarm horn sound 1 beep per second, gas has
been detected. Evacuate everyone from the building.
If the unit alarms and you are not testing the unit, it is warning you of a potentially dangerous
situation which requires your immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
USING THE SILENCE FEATURE
NEVER disconnect the power to your alarm to silence the horn - use the Silence feature. Disconnecting
the alarm removes your protection!
• The Silence feature is intended to temporarily silence the horn while you identify and
correct the problem.
• To use the Silence feature, press and release the SILENCE button until the horn is
silent.
• If the SILENCE button is pressed while the alarm is in the silence mode, the alarm will
start sounding again.
WHEN THE CO ALARM SIGNAL IS SILENCED: The CO alarm will remain silent for up to 4 minutes
(with the red LED blinking on approx. every 10 seconds, until reset) and then return to normal
operation. It will continue to monitor the air for CO. Ventilate area. After up to 4 minutes, depending
on the level of CO detected, if CO levels remain potentially dangerous, the horn will start sounding
again.
WHEN THE GAS ALARM SIGNAL IS SILENCED: The alarm will remain silent for approximately
20 seconds (with the blue LED blinking on approx. every 10 seconds, until reset) and then return to
normal operation. Ventilate area. If the gas has not cleared within the silence period, the unit will go
back into alarm.
IMPORTANT!
The Silence feature is intended to temporarily silence the alarm horn. It will not correct a CO or Gas
problem.
