Camden Door Controls CM-850 – Frequently Asked Questions

1) Can the Camden CM-850 switch a maglock directly, or does it need a relay?
The CM-850 rocker switch is rated 10 amps and wired as SPDT with common, normally closed and normally open contacts, so it can break the power run to a maglock directly without an interposing relay for typical mag current draw. Wire the mag through the N.C. leg so the rocker drops power when thrown, or use the N.O. leg to energize a strike. The switch is rated for 100,000 cycles.
2) Is the Camden CM-850 momentary or maintained?
Both. The CM-850 is a momentary or maintained SPDT rocker, so the same part covers a quick release pulse for a strike and a hold-open condition where reception wants the door unlocked until they throw it back. That is the switch selection that decides whether a maglock stays down, so it matters more than any dimension on the part.
3) Will the Camden CM-850 fit in a single gang box under a reception counter?
Yes. The CM-850 ships on a single gang mounting plate and the switch body measures 2-3/8 x 2-3/8 x 5/8 inches. It is a surface mount part from Camden's CM-800 Series intended for under counter or under desk mounting, so the shallow 5/8 inch depth is what lets it sit under a countertop lip without fouling a knee space.
4) Can the Camden CM-850 be mounted outdoors or in a wet area?
No. The CM-850 is one of the under counter and desk mount models in the CM-800 Series and does not include an enclosure. For an exterior or wash down location, go to the CM-810 or CM-820, which include a NEMA rated enclosure.
5) Does the Camden CM-850 need network or wireless setup?
None. It is a hardwired contact switch with no wireless communication and no programming, so it drops into an existing access control run or straight into the lock power circuit. Terminate common, N.C. and N.O. and it works.
6) Should I use a remote release rocker switch like the CM-850 or a push button for a reception desk?
A rocker like the CM-850 is the pick when someone needs to hold the door unlocked, because it does maintained as well as momentary. A push button only pulses. If your receptionist props the entry open during business hours and locks it after, the maintained position on the rocker is the reason to buy this instead. For pulse-only egress or release you do not need the maintained function.
7) Can one Camden CM-850 release a door and trigger an alarm or indicator at the same time?
Yes, that is what the SPDT arrangement gives you. Throwing the rocker opens one leg and closes the other, so the N.C. side can drop a maglock while the N.O. side simultaneously signals an indicator or annunciator. One switch, two circuits, one action.
8) Is the Camden CM-850 suitable for a commercial building or is it a residential switch?
Commercial rated, and the 100,000 cycle switch life is what backs that up. In a reception area seeing a few hundred releases a day, that is years of service. It is used for releasing maglocks or door strikes, and can also drive an alert or alarm indicator instead of a lock.
