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.
