Functional check
A visual inspection and a functional check must be performed for
each device monthly. After the functional check the device is
muted for 10 min, even when an alarm will be triggered. After
10 min the device will switch to normal mode again.
– 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).
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. After 10 min
the device will switch to normal mode again.

replace the batteries.
