Functional check
A visual inspection and a functional check must be done for each
device monthly. After the functional check the device is muted
for 10 min, even when an alarm will be triggered.
– The device is in normal mode (no signal). To perform the
functional check press and release the button (< 2 s). (6) ->
Siren sounds 3 times ≥85 dB(A), LED flashes red, emergency
light on. Then LED flashes red once every 10 s (muted). After
10 min the device will switch to normal mode again.
If the functional check fails the device is defective and must be
replaced.
Siren off (alarm signal)
If you press and release the button (< 2 s) of a device that has
triggered an alarm, then the device stops sounding, emergency
light turns off (delay up to 16 s) and LED flashes red once every
10 s (muted). After 10 min the device will switch to normal mode
again.
Polluted smoke chamber/weak battery
If the siren sounds short 3 times every 43 s (polluted smoke
chamber), then you have to replace the device. If the siren
sounds short once every 43 s (weak battery), also then you have
to replace the device.
