Camden CM-30 Series Square Green LED Illuminated Push/Exit Switch

Yes. The CM-30 uses a single gang face plate, so it mounts to a standard single gang box or mud ring. Overall the unit measures 4-1/2 x 2-3/4 x 2-1/2 inches, so allow for the depth behind the plate when you are working in a shallow box or a hollow metal frame.

Both are the same square green illuminated request to exit button. The difference is what happens after you press it: the standard version is momentary only, so the lock releases while the button is held and re-secures immediately. The timer version holds the release for a timed interval, which is what you want on a door that has to stay unlocked long enough to walk through with a cart or a wheelchair. Camden also builds a double break version, the CM-30EE, where electronic time delay with double break circuitry is called for.

The CM-30 Series REX switches are stated as UL compliant, ADA compliant, and conforming to NFPA code requirements. That is the combination an institutional or MRO buyer needs on a controlled egress opening where the button is the means of exit.

The CM-30 is a single gang device measuring 4-1/2 inches by 2-3/4 inches, which is wider than most aluminum storefront stiles. For narrow frame mounting, the SDC 410 Series is an illuminated push button exit switch specifically built with a narrow frame mount. Keep the CM-30 for wall-mounted single gang box locations where the full 2-3/4 inch width is available.

The nearest peer is the SDC 420 Series, an illuminated push button exit switch with 2 inch buttons. Like the CM-30, it is an illuminated request-to-exit push button rather than a plain unlit contact. The CM-30 itself is a single gang illuminated switch with SPDT Form 'C' contacts rated 10 A at 30 VDC on 12/24 VDC, with a green button. If the opening needs a narrower mounting footprint instead, the SDC 410 Series is an illuminated push button exit switch built for narrow frame mounting.

They mount alike but they are not the same device. The Dortronics 5211-MP23 is a 1-9/16 inch diameter red mushroom push button on a single gang plate, marked "Push to Exit"/"Emergency Release" - an unilluminated mechanical actuator with panic-style signaling. The Camden CM-30 is a green LED illuminated square push/exit switch, also single gang, with SPDT Form 'C' contacts rated 10 A at 30 VDC and a 14 mA LED draw that needs 12/24 VDC at the device. If you swap in the Dortronics you drop the illumination and the red mushroom changes what the button communicates to occupants.

Stay with Camden. The CM-30 is ordered either without a timer or with a 30 second timer, and where electronic time delay is required Camden offers the CM-30EE with double break circuitry. None of the mushroom-button alternatives - the Dortronics 5210 Series, SDC 430 Series, or SDC 440 Series - are described with an onboard timing function, so those would need a separate timer module in the circuit.

Both are aimed at code-driven openings. The SDC 420 Series is an illuminated push button exit switch described with 2 inch buttons and code compliance. The Camden CM-30 is a UL compliant LED illuminated request-to-exit switch that conforms to NFPA code requirements and is ADA compliant, and it is used to control electric locks, electromagnetic locks, electric strikes, and low energy door operators, as well as for shunting, alarm bypass, and timed functions.

Green square buttons are the normal-use request to exit device: people press them every day to leave, so the button is flush, illuminated and sized for repeated use. A red mushroom button is for emergency release, where the large head has to be hit fast and read as an emergency control, and it is usually labelled as such. If the opening needs both, you install both. For the emergency release role ZenSupply carries the Dortronics 5210 Series 1-9/16 inch red mushroom button on a single gang plate marked Push to Exit / Emergency Release, and the SDC 440 Series with a 2-5/8 inch mushroom head.

For industrial traffic, the SDC 430 Series is a heavy duty industrial mushroom button switch with a 1-1/2 inch round button, and the SDC 440 Series steps up to a 2-5/8 inch diameter heavy duty mushroom. The Camden CM-30 is a commercial-rated illuminated push/exit switch with a green LED and SPDT Form 'C' contacts rated 10 A at 30 VDC; it suits lobby, corridor, and office-side request-to-exit locations where a lit, ADA compliant button is wanted.

By stated button size, the SDC 440 Series is the largest at a 2-5/8 inch diameter mushroom, followed by the SDC 420 Series at 2 inch buttons, the Dortronics 5210 Series mushroom at 1-9/16 inch diameter, and the SDC 430 Series at 1-1/2 inch round. The Camden CM-30 takes a different approach to visibility: a square green LED illuminated face on a single gang plate, so it reads in low light rather than by sheer size.

Yes. Besides releasing electric locks, maglocks, electric strikes and low energy door operators, the CM-30 is used for shunting, bypassing alarms, request to exit signalling and timed functions. The SPDT Form C contact is what makes that range possible, since you can wire the normally closed side into an alarm loop and the normally open side to the lock.

Standard finish is US32D / C32D, satin stainless. That is the finish most commercial lever trim, push plates and exit device hardware is specified in, so it lines up with the rest of a typical satin stainless opening.

Hardwired. There is no wireless communication on the CM-30, so it needs a wire run back to the lock power supply or access control panel. Plan the conduit or wall fish before you set the box.
