Camden Door Controls CM-550SK – Frequently Asked Questions

1) Can the Camden CM-550SK keypad be mounted outdoors on a gate or exterior door?
Yes. The CM-550SK is rated for indoor or outdoor use, with an IP68 weather rating, a cast metal housing and a metal backlit keypad. Operating range is -40F to +140F (-40C to +60C), so it holds up in northern winters and hot exterior walls. It surface mounts, so no back box cutout is needed in the door frame or wall.
2) Does the Camden CM-550SK keypad support a request-to-exit device and door position monitoring?
Yes. There is a Request to Exit input for a push button, motion sensor or exit device switch on the secure side, plus alarm conditions for door forced open and door ajar, and a tamper alarm output you can run back to a panel. Door open time and alarm time are both adjustable: time delay is 0 to 99 seconds and alarm time 0 to 3 minutes.
3) How many door codes can the Camden CM-550SK hold, and how long are they?
Up to 20,000 users, with 4 digit codes. That capacity suits a multi-family building or a facility where every tenant or staff member gets their own code rather than everyone sharing one. It is a standalone keypad, so codes are programmed at the device itself, not from a head-end system.
4) How much wall space does the Camden CM-550SK take up, and will it fit on a narrow door mullion?
The keypad measures 5 x 3-1/4 x 1-1/8 inches. At 3-1/4 inches across its narrow dimension it will not sit on a typical narrow aluminum storefront stile, so on a glass front entry plan on mounting it to the adjacent wall, a jamb or a mullion wide enough to take it. Since it surface mounts, you only need a wire pass-through and fasteners, not a recessed box.
5) Can the CM-550SK keypad be used to run something other than a door, like an overhead door or equipment?
Yes. Besides electrically locked doors, it is used to activate or deactivate machinery, equipment, overhead doors, automatic door operators and other electrical devices. The dry Form 'C' contacts give you both normally open and normally closed, so it drops into an operator's activation input or an equipment start circuit the same way it drops into a lock circuit, within the 1 A at 30 VDC contact rating.
6) Do I need a separate controller or access panel with the Camden CM-550SK?
No. It is a standalone device, so the code database and relay are in the keypad itself and no panel or software is required. That also means all the switching happens at the reader side of the door. If your facility standard calls for the relay to sit on the secure side of the opening, a keypad that is wired back to a separate controller is the better architecture.
7) Where can I get the wiring diagram and programming instructions for the Camden CM-550SK keypad?
Camden publishes both a full installation and programming manual and a spec sheet for the CM-550SK, and ZenSupply hosts them with the product. The manual covers wiring the relay outputs, the REX input and tamper, and the programming sequences for adding and deleting user codes and setting the door open and alarm times.
