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

melody (wired) and pre-listen a melody.

pressed different menus are entered. The status LED normally lights up steadily, but when a menu is open it
flashes once / second.

Select volume with + and -. Each press of the button will increase / decrease the volume one step. Accept and
save the current volume setting by pressing press P for at least 3 seconds. The unit is now back in running mode.
