Every apartment is fitted with multiple 240V AC with 9V DC battery backup photoelectric smoke alarms. Photoelectric alarms detect combustion particles, designed for fast response to smouldering fires and to minimise false alarms.
These alarms are mains powered with wired interconnection and will provide an audible alarm at all locations simultaneously in the event of an alarm occurring. Only the originating smoke alarm will have a flashing RED LED.
Maintenance
The smoke alarms are virtually maintenance free. However, if there is any dust or lint buildup around the smoke alarm a vacuum cleaner may be used to clean the exterior of the unit (including slots on the cover). Testing and cleaning is recommended monthly. With higher levels of particulate matter in the air due to the local marine environment, more regular cleaning may be required to reduce the likelihood of false alarms. Please refer to the manufacturer’s manual for more details.
Do not immerse in or spray units with household cleaners.
If the unit gives a chirping sound once every minute, it indicates that the battery is flat and the unit needs to be replaced.
Troubleshooting
- Photoelectric smoke alarms are sensitive to high humidity, steam and dust.
- Insects are also a common cause for triggering smoke alarms. The smoke alarm internal sensor can be triggered by dust and bugs inside the unit. Regularly dust and vacuum your smoke alarm as per supplier maintenance guide.
- Additional design measures have been taken to ensure smoke alarm reliability in humid and coastal conditions. However, smoke alarms can confuse dense humid air particles for smoke particles in extreme humidity and may occasionally trigger smoke alarms.
