Electronic Carillon Systems

Automatic Bell Ringing Products

Equipment and locations

In general there are three areas that bell ringing equipment is located.

User controls

The control panel, sometimes referred to as a master clock, head unit, and may be an electronic carillon is usually located in a sacristy or office area. Many times to save long wiring runs, it may be installed in a balcony area near the tower. In all cases, no ladders should need to be used to access the control panel.

Relay panels

High current switching should be as near the bells as practical. The panels are weather resistant, but are is usually installed in a chamber below the bells. Precision motor control panels should be within sight of swinging bells for ease of programming.

To prevent moisture from accumulating in the panels, always route conduit to the bottom of the boxes.

Mechanical actuators

Tolling hammers, clappers and swinging motors are installed on the bells themselves and are usually supplied with at least an 18 inch pigtail. Junction boxes need to be located near enough to the actuator to allow connections. Flexible conduit is helpful to allow junction boxes to be located during the equipment installation. Separate low current conduits should be provided for swinging motor motion feedback signals (generally 12VDC logic signals).

Bells are always numbered from the largest (bell 1) to the smallest.

For swinging bells, the wheel side of the bell is where the swinging motor will be installed, and a tolling hammer will always be located on the opposite side from the wheel.

Riser diagrams

Riser diagrams shows the power supply, conduits and conductors required to be installed by an electrician in preparation for the installation of a bell ringing system. Electrical panels supplied by Chime Master are shown for location reference, but dimensions and final hookup may vary from the riser drawing.

Three phase power and 208VAC supply should be noted as early in the project as possible. Swinging motor systems should use three phase when available. Single phase motors are designed to be used at 230 VAC.
