WL-BELL
General description
Westerstrand WL-BELL is a part of Westerstrand Wireless Clock System for flexible installations. WL-BELL
is a fully automatic sound generator with built in audio player, amplifier and external loudspeaker. The device
has built in microcontroller and UHF receiver. It is fed from mains using an external ad/dc power supply (wall
adapter).
WL-BELL can be used in schools for class change, in industries for break signalling or for sending out general
messages or melodies. The unit is delivered with a SD memory card containing 16 pre-programmed sounds
including bells, ringtones, and melodies. The customer can easily add or replace the sounds on the card.
WL-BELL is controlled from a Master Clock in the QWTIMEIII product range. It is possible to create up to 8
zones with different break times and/or other messages. Start time, zone and melody number is programmed in
the Master Clock and is sent wireless to the unit prior to the play.
Alternatively, if the wireless feature is not supported by the Master Clock, the device can be connected via wire.
WL-BELL for outdoor use supports several ways of power supply. It comes with a plug for connection to 230V,
but it is also possible to use fixed installation. A third option is DC power.
