Relay Connections
When you are connecting to a door access device make sure you have
the following skills:
•
Understand basic wiring principles and techniques
•
Can interpret wiring diagrams
•
Have circuit wiring experience
Note:
The wiring must be installed in accordance with national and local
electrical codes.
Connecting the CT clock to a Door Strike
•
Unplug the relay screw terminal connector on the back of the
clock.
•
Connect the wires from the door access device to the screw
terminals. Plug the terminal connector into the socket on the CT
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.
