TROUBLESHOOTING
Chime does not sound:
•
Check Chime:
Disconnect wire from terminal marked “TRANS”. Have someone operate push button at front door while you mo-
mentarily touch the “TRANS” wire to terminal marked “FRONT”. You will see a small spark if push button, wiring, and transformer
are operating properly. Repeat the steps for “REAR” terminal and rear push button. If wiring between transformer and push button(s)
check out properly, replace chime.
•
Check Transformer:
Test transformer voltage output with a volt meter. If a volt meter is not available, momentarily touch the two
low-voltage terminals with a screwdriver. You will see a small spark if transformer is operating properly. If no spark is evident, replace
transformer.
•
Check Push Button(s):
Remove suspected push button from door frame, disconnect wire from terminals and touch bare wires
together. If chime operates, push button is defective. Replace push button.
Chime sounds but does not complete Westminster or Whittington (if applicable) tune:
•
Check Diode on Front Push Button:
Verify diode is attached securely to push button (see page 5). Chime may not function
properly if a diode is installed on more than one push button.
Note:
Some push buttons have pre-installed diodes. An additional diode
should not be added if the push button has a pre-installed diode. If eight-note tune still does not sound completely, replace diode (Type
1N4001-50V-1A, available at local electrical component supplier).
