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 30V,
but it is also possible to use fixed installation. A third option is DC power.

Work mode
WL-BELL has four work modes; wireless (default), wired with serial communication, wired with closing
contact, and play instantly when powered on. The work mode used is determined by a 4-pin DIP switch
accessible from inside the control box. In wired use, the unit may have a continuous power supply via an AC
adapter or only receive power, from the main clock, when it is time to play a melody.
1. Wireless communication. Start time, zone and melody number are sent wireless from the main clock.
Volume and zone are set via the +/- buttons inside the control box.
2. Wired communication. Start time, zone and melody number are sent by wire (RS485) from the main clock.
Volume and zone are set via the +/- buttons
3. Wired, closing contact. Play melody when a closed contact is detected.
Melody and volume are selected with the buttons.
4. Wired, play instantly when powered on. Play melody immediately when the power is turned on.
Melody and volume are selected with the buttons.
User Interface
To facilitate configuration WL-BELL has 3 buttons and four LEDs that are used to set volume, zone, select
melody (wired) and pre-listen a melody.
The LEDs are marked as follows:
Status

Zone
Unlock buttons
The buttons are locked by default to prevent unauthorized people from changing the settings.
To unlock the buttons, the P button must be pressed for at least seconds. Depending on how long the button is
pressed different menus are entered. The status LED normally lights up steadily, but when a menu is open it
flashes once / second.
Remark: To leave a menu without saving press – button for at least 3 seconds.

save the current volume setting by pressing press P for at least 3 seconds. The unit is now back in running mode.

Connection 230V
NOTE! When connecting 30V, the following applies:
- For fixed connection: connection to the mains supply must be made via an easily accessible
separate control switch ( -pin, 3mm contact gap)
- For plug connection: The wall socket must be close to the control box and be easily accessible.
Connecting speakers
The speaker, which is packed separately, comes with a fixed connection cable of 0.6 meters. Use this if the
speaker is mounted near the control box. If a longer distance is needed between the box and the speaker, the
cable can be spliced. Up to 50 meters is allowed with a cable dimension of 1.5 mm .
The speaker has an impedance of 4 Ohm and can, if necessary, be connected in series with another speaker. The
series connection can either be made directly in the internal connection terminal, see below, or in an external
connection box. Parallel connection is not allowed because the impedance will be too low.
Connection of one speaker Connection of two, series-connected speakers
