Test smoke alarm and backup batteries:
-
Press and hold the Test/Hush button for at least 3 seconds until the unit alarms.
-
Continue to hold for another 10 seconds to confirm all interconnected alarms activate.
-
To check the backup battery, repeat the test while mains power is turned off.
-
The alarm should sound indicating the battery is working. If it does not, replace the battery.
|
Clean smoke alarms:
- Vacuum smoke alarms to keep them free of dust particles, insects or cobwebs. This helps reduce false alarms and ensure any smoke can easily reach its internal sensing chamber.
- Spray insect repellent on a cloth and wipe the ceiling around the smoke alarm to act as a bug deterrent.
- Test the smoke alarm after cleaning.
|
Replace 9V backup batteries:
-
Press the button on the side of the unit (755PSMA4) or pull the alarm unit down (755PFM4) to reveal the 9V battery.
-
For efficiency and to avoid replacing batteries, upgrade to a rechargeable lithium backup alarm such as the 755RLPSMA4.
|
Replace the smoke alarms:
- Regardless of manufacturer, all smoke alarms have a limited life of 10 years from date of manufacture.
- Contact a licensed electrician to replace your unit.
