5. OPERATION AND TESTING
OPERATION: The alarm is operating once it is activated and testing is complete.
The photoelectric smoke sensor monitors the air for the presence of products of
combustion. When these levels exceed the alarm threshold the alarm will sound,
and be accompanied by the blinking red LED light, and voice message.
The carbon monoxide (CO) sensor monitors the air for the presence of CO. It
will alarm when there are high levels of CO present, and when there are low
levels of CO present over a longer period of time. When a CO condition match-
es either of these situations, the alarm will sound, and be accompanied by the
blinking red LED light, and voice message.
The CO sensor meets the alarm response time as follows:
At 70 PPM, the unit must alarm within 60-240 minutes.
At 150 PPM, the unit must alarm within 10-50 minutes.
At 400 PPM, the unit must alarm within 4-15 minutes.
TESTING: Test your alarm by pressing the test button until the unit chirps, then
release the test button. The unit will then emit three long beeps, "Fire!", three
long beeps, short pause, four short beeps, "Warning! Carbon Monoxide!", four
short beeps, pause, one beep. The alarm and voice will sound if the electronic
circuitry, horn, speaker, and battery are working. If the alarm or voice does not
sound, the unit must be replaced.
Warning: Due to the loudness (85 decibels) of the alarm, always
stand an arm’s length (about 2.5 feet) away from the unit or use ear
protection when testing.
Weekly testing is required to ensure proper operation. Erratic or low
volume sound (or no sound) coming from your alarm may indicate a defective
alarm and it should be returned for service. See PERMANENTLY DISABLE ALARM
/ DISCHARGE BATTERY section to determine how to prepare the unit for ship-
ment or disposal.
Warning: DO NOT use an open flame to test your alarm, you could
damage the alarm or ignite combustible materials and start a structure fire.
6. Alarm Visual and Audible Indicators
The following table describes the visual and audible alarm conditions the unit
may encounter and illustrates how the unit will indicate normal standby, alarm
and error conditions.
