Alarm Operation
Man-down and No-movement Alarm
Silent Alarm
The silent alarm is intended for potentially hazardous environments and for situations where
users do not want people nearby to know that an alarm has been triggered, in order to not esca-
late the situation. Silent alarms are accompanied neither by signals no other indications, giving
the possibility to send an alarm unnoticed.
If configured, the device will initiate a call giving the called party a possibility to listen in to get an
understanding of a threatening situation. For the details, refer to the Automatic Call after Alarm
on page 43.
Silent alarm is configured by the system administrator. For the details, please refer to the Config-
uration Manual, Unify OpenScape WLAN Phone WL4.

ALS will be triggered.

The Man-down alarm is triggered if the handset is tilted (default 45°) from the vertical plane for
a predefined period of time (default 7 s). The No-movement alarm is triggered if no movement is
detected during a predefined period of time (default 30 s).

ing phase (usually seven seconds long). During the warning phase, the handset alerts with:

cated by and includes the following information:
