
Connect the wires from the signaling device to the screw
terminals. Plug the terminal connector into the socket on the
clock. Only one (1) wire should be inserted into the terminal
block positions NO and COM, all wire splices should be done
externally. See the following diagrams for details.
Important! Relay contacts provide no power for signaling devices. The
relay is a dry contact closure rated 2 amps at 24VDC or 120 VAC.
Connecting a device or series of devices that draw more than the rated
amperage from the terminal will result in serious damage! It is
recommended to use the optional RB8 Relay Booster Box to control
devices that require more than 2 amps.
