Maintenance Tips
To keep your alarm in good working order, you must follow these steps:
• Test the alarm once a week by pressing the Test/Reset button.
• Vacuum the alarm cover once a month to remove accumulated dust.
• Never use detergents or solvents to clean the alarm. Chemicals can
permanently damage or temporarily contaminate the sensor.
• Avoid spraying air fresheners, hair spray, paint or other aerosols near
the alarm.
• Do not paint the unit. Paint will seal the vents and interfere with
proper sensor operation.
Move the CO Alarm to a remote location, to prevent possible damage or
contamination of the sensor, prior to performing any of the following:
• Staining or stripping floors or furniture, painting or wall-papering,
• Using aerosols or adhesives
WARNING: Reinstall the CO Alarm as soon as possible to assure
continuous protection.
The following is a list of substances that at high levels can damage the
sensor or cause temporary readings that are not CO readings:
• Ethylene, ethanol, alcohol, iso-propanol, benzene, toluene, ethyl
acetate, hydrogen, hydrogen sulfide and sulfur dioxide.
• Also most aerosol sprays, alcohol based products, paint, thinner, sol-
vent, adhesive, hair spray, after shave, perfume, auto exhaust (cold
start) and some cleaning agents.
7. Maintenance
NOTE:
This unit is sealed. The cover is not removable.
Due to the loudness of the alarm, we suggest that you place your
fingers over the sounder opening while testing your alarm.
Caution: Continuous exposure to the high sound level of this
alarm over an extended period of time may cause hearing loss.
Testing
To test the alarm, press the Test/Reset button. If the unit is operating
properly, you will hear 4 quick beeps – followed by 5 seconds of silence
– followed by 4 quick beeps. The display will show three “eights” and
then show a number – usually around 200). The red LED will flash along
with the beeps. Within several seconds the unit will return to monitor
for CO.
Note: You do not need to press the Test button to take a
CO reading.

Peak Level Memory Reset
Press the Peak Level button; with the button still pressed, press the
Test/Reset button for two seconds and release. The number on the dis-
play will turn to “0”, the memory will be cleared and the alarm will
begin monitoring for CO. The Peak Level memory is also reset when the
unit loses power.
6. Alarm Characteristics
Carbon Monoxide Alarm Indicator
When the alarm senses a dangerous level of CO,
the unit will emit a loud alarm pattern. The alarm
pattern is 4 quick beeps followed by 5 seconds
of silence, repeating for 4 minutes – and then 4
quick beeps once every minute as long as dan-
gerous CO conditions exist. The red Alarm LED
will flash the same pattern and the digital display
will indicate CO concentrations in parts per million (PPM).
