Bell Relay Connections
With the bell relay, you can program when bells or other devices will ring using the Bell
Wizard in your Terminal Manager software. You should have a qualified/certified
electrician connect your signaling devices to ensure proper connections and prevent
damage to your equipment.
To connect your signaling device(s) power source
Unplug the bell relay screw terminal connector and connect your wires from the
signaling device(s) power source to the “Common” and “Normally Open” screw
terminals, plug in the connector. See the diagram, Figure 6 and IMPORTANT! note
below.
IMPORTANT! Relay contacts provide no
power for bells or buzzers. They are rated
“dry” for 2.0 amps @ 24 VDC or 1.0 amp @
120 VAC. Connecting a device or series of
devices that draw more than the appropriate
amperage from the terminal will result in
serious damage! We recommend using the
RB8 Relay Booster Box to control devices
that require more than 2 amps. Contact your
dealer for information about obtaining an
