Camden Door Controls CM-331N – Frequently Asked Questions

1) What voltage does the Camden SureWave CM-331 touchless switch run on?
The CM-331 runs on 12VAC/DC, 24VDC or 24VAC, drawing 40 mA. It's a line powered switch, so it ties into your access control power supply rather than running on a battery. That voltage range covers most standard door control power supplies already on a commercial opening.
2) Will the CM-331 switch handle the current for my door operator or maglock circuit?
The relay is rated 3 Amps at 30 V, and it's a single SPDT contact. That's a dry contact suited to signaling an operator, controller or lock relay, not to carrying a heavy load directly. If your device draws more than 3A, switch it through a separate relay or the power supply's own output.
3) Can the CM-331 be wired fail-safe or does it have to be fail-secure?
Either. The contact configuration is field selectable, and the SPDT relay gives you both normally open and normally closed contacts at the switch. You set it at install to suit whether the lock releases or engages on activation.
4) What size electrical box do I need for a Camden CM-331 touchless switch?
It depends which faceplate you order. The CM-331 comes in single gang, narrow, and double gang faceplates, so pick the one that matches the box already in the wall or jamb. Narrow is the one to use where there isn't room for a standard single gang plate, such as a mullion or a tight jamb return.
5) Is the Camden CM-331 rated for outdoor use at an exterior entrance?
No. The CM-331 is an indoor, commercial-rated switch. For an exterior wave plate at a building entrance you need a weather-rated touchless switch instead. Mounting the CM-331 inside a heated vestibule is fine.
6) Does the CM-331 have a hold open timer, or do I need a separate timer module?
Timing is built in. The CM-331 carries its own hold open timer along with selectable motion sensing and relay operating modes, so you don't need an add-on timer to hold an operator or lock released for a set period. Relay operating modes are Event and Toggle, so it can either pulse for a timed cycle or latch on and off with successive waves, which is how you'd set up a room that needs to stay unlocked.
7) Can I tie a request-to-exit signal and a door position switch into the CM-331?
Yes, the switch takes both REX and door contact inputs. That lets it hold off or coordinate with an existing exit device REX and monitor door position, which matters on an opening where you don't want the wave sensor re-triggering an operator while the door is already open.
8) Can the wave range on the Camden CM-331 be adjusted so people don't set it off walking past?
Yes. The CM-331 uses an active infrared sensor with an adjustable operating range, so you can dial it in tight on a corridor or a narrow vestibule where foot traffic passes close to the plate. Motion sensing mode is also selectable.
9) What is the tri-color light ring on the CM-331 for, and can I add it later?
The light ring shows red, green or blue status at the plate, controlled either by the switch itself or remotely from your access control. It's a plug-in accessory for single gang, double gang and 6 inch round stainless faceplates, and the CM-331 is ordered either with or without it. If visual status at the door matters, specify the light ring version up front.
10) Can the CM-331 trigger a door operator wirelessly instead of running wire across the opening?
The CM-331 supports wireless communication and has the option for a wireless transmitter, so the activation signal can be sent to a receiver at the operator rather than pulled in conduit. The switch itself still needs line power at the plate, so you'll run power to the box either way.
11) How much wall space does a CM-331 touchless switch take up?
The switch measures 5.5 inches wide, 5.25 inches long and 2 inches high, and weighs 0.4 lb. Worth checking the 2 inch depth figure against the box and any conduit behind it before you commit to a tight jamb location.
