Camden Door Controls CM-1200 and CM-2200 Series flush mount key switches meet the demands of key switch controls, designed for use with standard 1", 1-1/8", or 1-1/4" mortise cylinders. CM-1200 is single gang (2-3/4" wide) and CM-2200 is narrow style (1-3/4" wide); both accept one or two switches and control overhead doors, electric locks, electro-magnetic locks, electric strikes, and motors.

BasisStructured, independently qualified product connection evidence
PreparationFit the aluminum bracket against the stud behind the faceplate. Insert the separately purchased mortise cylinder from the front and align its side grooves with the bracket retainers. If irregular grooves prevent fitting, file the retainers slightly; never remove them completely. Tighten the brass cylinder lock ring to secure the bracket. Fit the supplied switch in the selected bracket hole with its spacer ring and threaded washer. Align the cam centrally over the switch and check key operation before fastening the unit to the selected switch box, wall or receptacle box with the supplied screws. Select the mounting arrangement and compatible cylinder for the installation.
ElectricalBase configuration: Key Switch, (2) SPDT Momentary. For each used changeover pole, common plus NO or common plus NC requires two external conductors; common plus both NO and NC requires three. Apply that choice separately to each of the two supplied switches. Do not join independent commons by assumption. These are low-voltage circuit conductor counts, not physical cable-run counts. The supplied 18 AWG soldered leads do not specify field cable gauge. Common is grey; momentary NO is blue and NC orange. The maintained-contact chart lists both throw leads orange, so identify the actual terminal function before connecting. Cable type, gauge, shielding and physical run quantities depend on the selected controller/device and site routing. Optional LED circuits remain separate and require their selected DC option instructions. The standard-contact parts table and family specification give different contact ratings; verify the fitted switch rating. Contact ratings are not supply requirements.
