CX-12 PLUS
Door Interface Relay
INSTALLATION INSTRUCTIONS
1. GENERAL DESCRIPTION
Camden CX-12 PLUS Door Interface Relay provides all the functionality of the CX-12 and the CX-22 combined into 1 package.
In addition, a new Ratchet Relay mode is provided, making the CX-12 PLUS one of Camden's most versatile door control
relays available.
Used as a make/break relay (or Switching Network), it eliminates the binding of locked automatic doors, by delaying the door
operator until the strike or maglock de-activates first.
