Connecting the PC600 to a Door Strike
Unplug the relay screw terminal connector.
Connect the wires from the door access device to the screw
terminals. Plug the terminal connector into the socket on the PC600.
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. The relay is a dry contact
closure rated 2 amps at 24VDC or 120 VAC. Connecting a door strike
that draws more than the rated amperage from the terminal will result in
serious damage! It is recommended to use the optional RB8 Relay
Booster Box for a door strike that requires more than 2 amps.
