Connecting External Signal Devices (Bells & Horns)
The connections for an external signal device (bells, horns, buzzers, chimes, etc) are made via a
2-wire Green terminal block on the back of the clock above the power jack. Connections are
made by pressing the orange wire release tabs below each wire hole, fully inserting the wire and
releasing the clip. Gently pull on the wires to make sure they are firmly secured in the terminal
block.
In order to use a bell or horn a relay is required. Please call Acroprint or your Dealer to order the
relay (PN 01-0230-000).
When a signal is activated by the clock the internal contacts of the relay close and complete the
circuit. These internal contacts are "dry" and supply no voltage. Voltage applied to these
contacts must not exceed 30 volts. The relay then activates the 120v external signal device such
as:
65-0103-000 "Grille Horn"
65-0104-000 "4-1/4" Bell"
65-0105-000 "8" Bell"
