5. INSTALLING YOUR CO ALARM:   
CAUTION: This alarm should be installed by a 

competent person.

and maintenance of fuel burning appliances, 

including appropriate ventilation and exhaust 

systems. 
It does not replace a smoke alarm.

Detach the alarm from the mounting base by twisting 

counter clockwise.

Use the mounting base to mark up horizontally the

TEST FUNCTION:   

After installation and at least once per quarter, test 

your alarm to make sure it is operating correctly.

It is recommended to check visually every week if the 

green LED flashes correctly (every minute)
When the top button is pressed the alarm sounder 

will sound, and when the button is released, the 

alarm will make a self-test of the sensor and battery 

for approximately 9 seconds. During this delay the 

three LEDs will be flashed in sequence. The result 

of the test will be indicated after the test has been 

completed.  

If the test passes, the green LED will emit for 3 sec. 

If the test fails, a fault indication will be given (See 

section 11).
After the test function is performed, the alarm will 

need to recover for one minute before the next test 

can be done (to allow the sensor chamber to re-set-

tle after the test current is applied).
The alarm will also do a self-test every 24 hour and 

test the sensor for faulty sensor, drift or short circuit.
TIP: It is safe to cover the sound output hole with 

your finger during the testing to minimize the sound 

level emitted.
