Testing, monitoring and maintenance
Your smoke alarm is a life saving device and should be checked periodically in accordance
with CAN/ULC-S552. Regularly check that the red light on the smoke alarm blinks approxi-
mately every 45 s to show the units are powered. Replace the battery if the blinking stops.
Manually testing your smoke alarms
It is recommended that you test your smoke alarms after installation and then at least
weekly to ensure the units are working. It will also help you and your family to become
familiar with the sound of the alarms.
Press and hold the test button until the alarm sounds and the red light blinks
(see Figure 6 on page 14).
Release the test button. The alarm will stop sounding shortly after the button is released.
Repeat this procedure for all other smoke alarms in the system.
WARNING: Do not test with flame.
This can set fire to the smoke alarm and damage the house. We do not recommend
testing with smoke as the results can be misleading unless special apparatus is used.
When you press the test button it simulates the effect of smoke in a smoke alarm which it
could experience in a real fire. So, there is no need to test smoke alarms with smoke or flame.
Test/hush button to control nuisance alarms
The smoke alarms have a combined test/hush button to help you control nuisance/
false alarms.
