Camden CM-30EE LED Illuminated Exit Switch

Overview

The Camden CM-30EE is a 2-inch LED illuminated exit switch (Request to Exit / REX control) rated 30VDC, designed for electromagnetic lock release in access control door egress scenarios. The green backlit button with black 'Push to Exit' text provides high-visibility feedback in low-light corridors, stairwells, and emergency exit points. The fixed 30-second timer cuts power to the magnetic lock when activated, then automatically re-engages the strike after the dwell period expires — a common requirement in fire-rated door assemblies and secure facility egress paths. The CM-30EE uses a double-break circuit design: pressing the button interrupts power to the maglock immediately, even if the timer circuit fails, meeting NFPA code requirements for fail-safe egress.

Compatibility

The CM-30EE integrates with any electromagnetic lock control system expecting a 30VDC momentary SPDT (Single Pole, Double Throw) switch contact rated 10 amps. Common deployments pair it with networked access control panels (HID, Salto, DoorKing, Viking, etc.) via their relay outputs, or with dedicated strike power supplies in hybrid wired/networked installations. The unit operates on 12/28V with the supplied LED bulb (green), so verify your strike power supply outputs 30VDC before connecting. In-wall installation requires a standard single-gang back box, which is included.

Installation Notes

Mount the stainless steel faceplate flush to the wall or doorframe using the included tamperproof screws. Run the switch legs (C, NO, NC contacts) to your strike control relay or access control panel output. The fixed 30-second timer is non-adjustable on the CM-30EE (the CM-30AT variant offers an adjustable timer if you need different dwell periods). Ensure the strike power supply is sized for the lock's draw — the switch itself is rated 10A @ 30VDC, but the limiting factor is the maglock's inrush current. Test the double-break circuit by powering the lock, pressing the button, and confirming power to the lock drops immediately even if the timer circuit is disconnected.
