Camden SureWave CM-331 and CM-332 Touchless Door Activation Switches provide hands-free, active-infrared activation for compatible commercial automatic doors and access-control systems. Select the exact switch model for the needed relay outputs, faceplate style, accessibility graphics and LED option.

Choose the Controller Type

• CM-331 Series: Single-relay active-infrared touchless activation switch with one Form C/SPDT output. The offered models use stainless-steel faceplates and integrated red/green/blue LED rings.
• CM-332 Series: Dual-relay active-infrared touchless activation switch with two Form C/SPDT outputs and additional compatible door-control sequencing options. Offered with stainless-steel or black polycarbonate faceplates.

Available Faceplates and Models

• CM-331/41S-SGLR: Single-gang stainless steel with WAVE TO OPEN text and RGB LED ring.
• CM-331/41SW-SGLR: Double-gang stainless steel with WAVE TO OPEN text and RGB LED ring.
• CM-331/42R-SGLR: Six-inch round stainless steel, wheelchair symbol and RGB LED ring.
• CM-332/41S-SGLR: Single-gang stainless steel, WAVE TO OPEN and RGB LED ring.
• CM-332/42S-SGLR: Single-gang stainless steel, wheelchair symbol and RGB LED ring.
• CM-332/42SW-SGLR: Double-gang stainless steel, wheelchair symbol and RGB LED ring.
• CM-332/44S: Single-gang stainless steel with hand and wheelchair symbols; no RGB LED-ring suffix.
• CM-332/42: Black single-gang polycarbonate with wheelchair symbol.
• CM-332/42N: Black narrow-jamb polycarbonate with wheelchair symbol.

Features and Installation

• Non-contact infrared activation with a configurable standard sensing range of approximately 1–28 inches.
• Low-voltage 12–24V AC/DC operation for professional wired door controls.
• Plate geometry, graphics, relay count, lighting, price and shipping weight depend on the chosen model.

Choose the exact model from the selector. CM-331 and CM-332 are not electrically interchangeable where a second output relay is required. Check mounting dimensions, power supply, operator interface, sensing configuration and current installation instructions. This listing contains the switch model selected, not an entire automatic door operator.

SureWave CM-331 and CM-332: Key Technical Specifications

Camden SureWave active-infrared switches detect a hand motion near the plate and send a controlled relay signal to compatible automatic doors or access-control equipment. CM-331 uses one Form C relay; CM-332 uses two Form C relays and can support additional sequencing functions. Select the controller family and faceplate layout that the opening actually needs.

Available Models and Faceplate Selection

Benefits for Automatic Door Systems

• Touch-free entry: Users wave a hand near the plate instead of contacting a physical pushbutton.
• Flexible wall mounting: Choose the correct gang size, round plate or narrow jamb to fit the available space.
• Sequencing options: CM-332 dual-relay hardware is suited to specified interlocking or bi-directional door operations.
• Selectable graphics: Hand, wheelchair and WAVE TO OPEN text options support user guidance at busy entrances.
• Visual feedback: -SGLR models add a tri-color LED ring for configured activation or status indication.

How to Select and Install

1. Confirm whether the control design requires one relay (CM-331) or two independent outputs (CM-332).
2. Choose the exact faceplate shape and size for the site's electrical box, mullion or accessible mounting height.
3. Choose an -SGLR model when the illumination option is required; do not assume a ring is installed on non-SGLR variants.
4. Use a compatible 12/24V AC/DC supply and verify output relay load limits and door operator inputs.
5. Set sensing range, time delay and contact functions; conduct walk tests to minimize unintended activation.
6. Follow the door operator and applicable accessibility and life-safety requirements.

Note: This listing supplies a selected wired activation switch; it does not include an automatic door operator, lock, independent receiver or wireless activation system unless stated in the specific configuration.
