9. Operation and Testing
Operation
The alarm is operating once it is activated and testing is complete (see “TESTING” below). When CO is detected,
the unit sounds a loud alarm. See Section 1 for alarm signal descriptions. In high levels of CO, the unit will go
into alarm in a shorter period of time than at low levels of CO.
Testing
Test your alarm weekly, or after returning from a vacation or absence, by pressing and releasing the button
quickly. A quick beep will confirm the button has been pushed followed by the test sequence. See Other Alarm
Visual and Audible Indicators table. The alarm will sound if the electronic circuitry, horn, and batteries are work-
ing. If the alarm does not sound, or gives erratic or low volume sound, the unit must be replaced.
WARNING: DUE TO THE LOUDNESS OF THE ALARM, ALWAYS STAND ABOUT 1 METRE AWAY
FROM THE UNIT OR USE EAR PROTECTION WHEN TESTING.
BUMP TEST MODE
This alarm includes a “bump test” mode that will allow the alarm to be qualitatively tested during field
service using commercially available aerosol CO.
1. Hold the test button down for 10 seconds.
2. The unit will chirp 3 times indicating the start of test mode.
3. The Green LED flashes once per second during test mode.
4. Apply the commercially available aerosol CO.
5. CO alarm sounds if CO reading is above 40 ppm.
6. The alarm will automatically exit from the bump test mode after 2 minutes followed by reset.
NOTE: The test can be terminated manually by pressing the test button.
