The smoke detector will activate the built in sounder upon sensing smoke particles.

The red indicating LED will flash once every 40 seconds to show that the alarm is powered and it
has performed an automatic self-test. The built in sounder will provide a minimum sound
output of 85dB at 3m.

Pressing and holding the “Test/Hush” button will perform a self test and sound the horn – checking the chamber, electronics and horn.
Momentarily pressing the “Test/Hush” button when an alarm is sounding will set the alarm into “HUSH” mode. This reduces the sensitivity for a period of 10 minutes, after which the alarm automatically resets – providing control over false alarms.

The alarm is not powered until it is connected to the twist on base, thus avoiding battery power consumption during storage and prior to installation.
