Transceiver U922
TD 91836GB
Man-Down Alarm (option)
The U922 can be equipped with an tilt sensor. If the user falls down or if the alarm
transmitter is tilted more than 60º, a warning tone is heard after 7 seconds. The
alarm can be interrupted by pressing the OK-button or by moving the transceiver
to an upright position again. If the alarm is not interrupted, a two-tone localisation
signal is generated confirming that the alarm has been sent. When the warning
signal is heard, the alarm can be delayed for ten minutes by pressing the
OK-button.
Note:
The transceiver can either have a man-down alarm option or a no-
movement alarm option, not both.
No-Movement Alarm (option)
The alarm transceiver can be equipped with a sensor for no-movement alarms. The
no-movement alarm is activated if the transceiver has not been moved within a
preset time period. Before the alarm is transmitted, a warning signal continuously
sounds. If the unit has not moved during this time, the warning signal sounds and
an alarm is transmitted. To prevent the alarm transmission, move the unit or press
the OK-button, while the warning signal is heard.
Note:
The transceiver can either have a man-down alarm option or a no-
movement alarm option, not both.
External Alarm (option)
The U922 can be ordered with an external alarm input. It is located at the bottom
of the cover on the battery pack. The alarm can be programmed for an opening or
closing function. The input is intended for connection to any kind of external alarm
device, for example a gas or smoke detector.
Alarms are normally
generated by connect-
ing the input to
ground (< 5 kohm ).
Tele-plug, 2,5 mm
Activating and Deactivating Different Alarm Functions

• Button 3: unprogrammed
However, it is possible to select other combinations to activate the different alarm
types when programming the pocket unit. The hot-keys can also be reserved for
other functions. For example, they can be used to activate different system
functions.
