IMPORTANT:

Where should I mount the smoke alarm?

Mounting smoke alarms

IMPORTANT:
The performance of smoke alarms mounted on walls is unpredictable and this mounting position is not recommended when ceiling mounting can be implemented.
Incorrect orientation of smoke alarms may decrease operational effectiveness.

Smoke, heat and other combustion products rise to the ceiling and spread horizontally. Mounting the smoke alarm on the ceiling, in the center of the room, places it closest to all points in the room. Ceiling mounting is always best, and take care to avoid dead air spaces when mounting. Dead air spaces generally occur at the peak or apex of cathedral ceilings and the corner junction of walls and ceilings.

CEILING/ WALL JUNCTION

When mounting smoke alarms on the ceiling, locate it at least 300mm away from the side wall and 300mm away from any corner to avoid dead air space.

If ceiling mounting is not possible, the recommended position for wall mounting is between 300mm and 500mm of the ceiling.

CATHEDRAL CEILING / A-FRAME CEILING

When mounting smoke alarms on Cathedral / A-frame ceilings, position the alarm at least 500mm away from the peak of the ceiling, but no further than 1500mm away from peak.

What do I do if my smoke alarm starts chirping?

If installing the smoke alarm for the first time, please ensure the yellow battery installation tag has been removed. PSA smoke alarms will emit an audible chirp at regular intervals to indicate that the 9 volt back-up battery is low in charge and needs to replaced.
The procedure on how to replace the 9 volt battery differs slightly depending on the smoke alarm model. Please use the information below as a guide and refer to your smoke alarm’s Installation and User Manual for the correct procedure.

Smoke Alarms which are model LIF5800RL, LIF5800RF, LIF10YI and LIF10YPE, LIF10YPEW, LIFPE10 the batteries cannot be replaced. Contact PSA technical team for information if you have the aforementioned models and are experiencing chirping. Should your smoke alarm be close to 10 years old, it is most likely at its expiry and due for replacement.

Have you pressed the Hush feature? Pressing the hush button on the smoke alarm will cause the smoke alarm to beep or chirp for 10-15 minutes. The Hush feature is designed to desensitize the smoke alarm from false alarms, with the chirping indicating hush mode is active. Hush mode will automatically reset once the 10-15 minute chirping cycle is over. Pressing the hush button before this cycle if over will restart another 10-15 minute cycle of chirping.
