A6. OPERATION, TESTING
OPERATION:
The CO alarm is operational once A.C. power is applied (green LED is on)
and testing is complete.
TROUBLE CONDITION:
The internal microcontroller continuously monitors the sensor
and other critical components. If an internal failure of any of these components occurs the
alarm will flash the LED red, beep once every minute and the LED will blink yellow
continuously.
ALARM CONDITION:
When the concentration of CO gas reaches a hazardous level, the
alarm will sound within the time limits outlined in section A2. The LED will light red
continuously when the alarm sounds. The alarm signal will sound 4 short beeps in every 6
seconds. The accommodation spaces should be well ventilated when household cleaning
supplies or similar contaminants are used. See section A7 for false alarm information.
Voice message: during alarm condition, the instructions will be announced in the following
sequence: “Beep, beep, beep, beep, 70 ppm (or 150 ppm, or 400 ppm depending on the
level of alarm) carbon monoxide gas alarm, operate reset button, beep, beep, beep, beep,
call your emergency services, immediately move to fresh air”. These messages will be
announced continuously, until the reset button is pushed, or the CO gas concentration
drops below the alarm threshold level.
TESTING:
Test your alarm by pushing the TEST / RESET button which is located on the
back of the cabinet and hold it dow n for a minimum of 5 seconds. This will simulate a CO
concentration of approximately 400 ppm CO gas and sound the alarm if all the electronic
circuitry, and buzzer are working.
Voice message: during testing condition, the instructions will be announced in the following
sequence: “Beep, beep, beep, beep, testing, testing, carbon monoxide gas alarm, operate
reset button, beep, beep, beep, beep, testing, testing, call your emergency services,
immediately move to fresh air”.
DO NOT TRY TO TEST THIS ALARM IN ANY OTHER WAY.
If no alarm sounds check the fuse or circuit breaker supplying power to the “clock
radio/CO alarm”. If the alarm still does not sound the unit may be defective or have other
failure and should be returned for service (SEE SECTION A11).
TEST THE ALARM
WEEKLY
TO ENSURE PROPER OPERATION.
Erratic or low sound coming from your alarm may indicate a defective alarm, and it
should be returned for service (SEE SECTION A11).
RESET:
The CO alarm will automatically reset itself when the CO gas which caused the
alarm has cleared. The alarm will however alarm for at least 4 minutes if it is not manually
reset. You can also silence the alarm by pushing the TEST / RESET button. If CO is still
present the alarm will alarm again within 6 minutes if the CO concentration level is at 70
ppm or greater. If the alarm sounds again after reset, go to section A2... WARNING...If
alarm signal sounds:...and follow instructions 1), 2), 3), 4).
