(2)Ensure there are no fumes in the area (e.g. paint,
thinners, alcohol, hair spray, chemical cleaners aerosol sprays etc).
(3)Ensure there is no outdoor source of CO in the vicinity (e.g. a car with engine running, heavy traffic, heavy air pollution, barbecue fumes etc).
(4)Press the test/hush button to silence the alarm.
If the unit continues to sound it is possibly defective and should be replaced, follow the instructions in section 5 on “How to disconnect and remove your alarm” and then see section 10 “Getting the CO Alarm Serviced”.
4. TEST/HUSH BUTTON DOES NOT SILENCE ALARMS:
If there are a number of alarms interconnected and they are all sounding, pressing the test/hush button on the unit sensing CO (i.e. the one with the red light flashing) will silence the system. Pressing any other test/hush button will not silence the alarms. Hush button will only silence the unit once at CO levels less than 300 ppm CO during a CO incident.
