CX-PC-3 Lock Out Relay
CAMDEN DOOR CONTROLS offers a Lock-Out Relay (L.O.R.) for any automatic door operator: EM-2 for spring close DC motors; PC-3 for power assist, handicap operators, or regular operators; and EH-4b for electro-hydraulic/pneumatic operators with AC motors/solenoids.
Camden EM2/PC-3/EH46 Lock-Out Relays are designed to be used with safety sensors such as Optex Model OA-601C.
Since the safety sensor would normally detect the door when it is closing, a relay lockout device is used to bypass the sensor in the closing cycle only.
The safety sensor is switched back into the circuit once the door comes to the fully closed position.
An added feature of our L.O.R.ís is the ability to connect optional door beams. Should someone walk back into the path of the closing door, they would break the beam, which in turn would put the safety sensor back into circuit, turning on the operator safety.
This type of installation provides for maximum safety and is strongly recommended for swing doors.
