→Automatic Bell Ringing Products
==== 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.

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.
