Installing a Bell/Buzzer
Installing a Bell/Buzzer
The following instructions will guide you through connecting your bell
or buzzer to the relay connection on your Infinisource time clock.
WARNING: The relay connection on the time clock handles
electricity from a standard 120 VAC circuit. Because of the
danger of electrical shock, Infinisource
strongly recom-
mends that you have a qualified electrician perform the fol-
lowing procedures.
ETC Clocks
An ETC model clock will have either a 2-screw or a 4-screw card
reader. The instructions to installing the bell or buzzer vary slightly
depending on which configuration you clock has.
Determining Your Hardware Configuration
Remove the clock from the wall (if it has already been mounted), turn it
over and examine the back. You will see six large screws around the
edge of the clock case. These screws hold the back panel of the clock
case to the front piece.
In addition to the six large screws you will see four smaller holes on the
left side of the clock’s back panel. This is where the card reader is held
in place. Depending on which hardware model you have, these smaller
holes may contain four screws, or they may contain only two, with the
other two holes left empty.
Count the screws used to hold your card reader in place and follow the
instructions for the appropriate hardware type. Procedures for both
types are included below.
