4 Basic Operation
Note: The Ascom a51 Alarm Transmitter may have functions other than described here,
depending on the pre-programmed parameters.
4.1 Switch the Alarm Transmitter On/Off
Insert/remove the battery.
4.2 Mute the Beep/Vibrator/LED Signal
Press the Mute button.
4.3 Charge the Battery
Three battery levels exist:
•OK
•Warning
• Shutdown
During the battery warning phase, a beep signal played once each 10 s. during one
minute and a fast flashing red LED indicates a low battery. Place the Alarm Transmitter in a
Single Charger or a wall mounted Charging Rack. If a Charging Rack is used for charging,
just insert the Alarm Transmitter without opening the clip, to make it fasten securely. Be
sure to hear a beep and see the LED charging indication when inserting the Alarm
Transmitter in the charging rack.
A slowly flashing orange LED indicates charging. A green steady LED indicates a fully
charged battery. It takes approximately two hours to fully charge the battery. Note that it is
normal for the battery to get slightly warm while charging.
If the battery level goes below the shutdown level, a shutdown warning beep is played for
10 s. after which the Alarm Transmitter enters deep sleep. The best way to wake up the
Alarm Transmitter from deep sleep is to put it into a Single Charger or wall mounted
Charging Rack. It is also possible to make a cold start, see
4.1 Switch the Alarm
Transmitter On/Off on page 6.
Note: While the Alarm Transmitter is attached to the Single Charger or put in the wall
mounted Charging Rack, only the push-button alarms (Alarm- and Soft-alarm button) and
the Pull-cord alarm are enabled. This means that, if existing, Man-down & No-movement
alarms are deactivated. The Location Function (IR and LF) is also deactivated. (If a push-
