Camden Door Controls CM-3000/3100 Series Exit Switches are heavy duty push-buttons designed for industrial and commercial applications where illumination is required. Buttons are 1 5/8" (40mm) in diameter, available in red or green, with a 1/4" thick brushed aluminum faceplate in 1 3/4" or 2 3/4" widths. The switches are UL/CSA approved, rated 10 amps @ 30V DC, for either momentary or maintained operation.

Product specifications
Low-voltage wiring Required
BasisStructured, independently qualified product connection evidence
PreparationProvide the narrow door-jamb mounting arrangement for this model. Align and secure the brushed aluminum faceplate with the supplied mounting hardware, leaving room behind it for the contact block, LED and wiring. Verify clearance against the delivered assembly: the dimension table and side drawing give different depth figures. Select the actual surface or flush mounting arrangement before installation.
ElectricalCM-3140 uses a N/C SPST contact block with maintained push/pull action. For a selected direct 12/24 VDC control circuit, connect the two-conductor switching loop to common and normally closed. The LED supply is separate: connect two supply conductors at X1/X2 directly for 12 VDC; for 24 VDC put the supplied resistor in series with either X1 or X2. These interface counts do not state how many cable jackets/runs to pull. Field wire type and gauge are not specified by this manual; factory lead sizes are not field cable requirements.
