Wiring
Wire in accordance with NFPA 72 and CAN/ULC-S524. Be
sure to observe the polarity of the wires as shown in Figure 3.
Transient protection caution
The module requires transient protection for installations that
connect electromechanical bells or horns to output circuits. The
module's circuitry requires a bipolar transient protector
(P/N 235196P) for protection against transient spikes caused
by the inductive load of bells or horns.
Connect the bipolar transient protector assembly across the
terminals of the bell or horn electrically closest to the module.
The bipolar transient protector is not polarity-sensitive.
Locate bells and horns at least 6 ft. (1.83 m) from the module.
