HELPFUL HINTS
• Electrical work must be in accordance with national and local electrical codes. If in doubt,
consult a qualified electrician. Turn power off at fuse or circuit breaker before installing/
replacing transformer.
•Many chimes, bells, and buzzers are installed with a 10 Volt, 5 Watt transformer. This chime
requires a minimum 16 Volt, 10 Watt transformer.
• For replacement installation, identify and tag wires before removing them according to terminal
markings: “F”-Front Push Button, “R”-Rear Push Button, and “T”-Transformer.
• For new installations install #20 AWG bell wire in pairs from push button(s) and transformer to
chime. Do not pinch wire or damage its insulation. Heath
®
/Zenith accessory wire (No. 196C or
No. 199C) is available for chime installations.
• Clean wood, plastic, and metal parts with mild soap and warm water. Never use cleaners or
polishes. Never use any fluids on the mechanical chime mechanism.
5. Mount push button(s) to door frame(s). Run two No. 20 AWG bell wires from push button(s) to
the chime location. Strip away 1/2" of insulation from end of wires. Connect each wire to push
button(s) (see Figure 1).
