Sensor Switch CM PDT 10 Dual-Tech Ceiling Occupancy Sensor

The Sensor Switch CM PDT 10 is a ceiling-mounted, dual-technology occupancy sensor that combines PIR and microphonics to reliably detect presence in open office areas and control lighting automatically.

Designed for open-plan and cubicle-style workspaces, the CM PDT 10 Extended Range uses overlapping sensing methods to catch both visible motion and subtle audio vibrations from typical office activity. Its 360° coverage and ceiling-mount format make it an unobtrusive solution for reducing wasted lighting energy while maintaining occupant comfort. No field calibration is needed, and programming is handled through simple push-button controls.

How does the CM PDT 10 detect people in open office layouts?

The sensor pairs passive infrared (PIR) line-of-sight detection with microphonics that pick up small sounds and vibrations, improving recognition of occupants who are seated and moving minimally. This dual approach reduces false offs compared with sensors that rely on a single technology.

• PIR provides 360° circular motion coverage from the ceiling vantage point
• Microphonics sense low-level activity within cubicles or workstations
• Overlapping zones ensure consistent detection across open areas

What installation and setup steps are required?

Mount the sensor to a standard ceiling electrical box and connect to the lighting circuit; the unit is intended for straightforward installation without specialized calibration tools. Settings like time delay and operational modes are adjusted with push-button controls on the device.

• Ceiling-mount design fits typical junction boxes
• Push-button programming avoids complex software or apps
• Available test mode helps verify coverage during installation

Which features help administrators fine-tune performance?

The CM PDT 10 includes adjustable time delays, a convenient test mode, and factory-balanced sensitivity so installers don’t need to perform in-field sensitivity tuning. These options let facility managers tailor how quickly lights switch off after vacancy and confirm coverage before closing the ceiling.

• Adjustable time delays for vacancy response control
• Test mode for easy verification of detection zones
• No field sensitivity or calibration required for reliable operation

How does this sensor contribute to energy management goals?

By switching lighting based on true occupancy—captured through motion and microphonic inputs—the CM PDT 10 reduces hours of unnecessary lighting use in open-plan offices. Its ceiling placement and extended-range coverage make it effective across larger communal spaces, helping lower electricity consumption without disrupting occupants.

• Automatically turns lights off in unoccupied zones to save energy
• Reduces manual overrides and missed shutoffs in open areas
• Supports corporate energy-reduction policies with reliable occupancy sensing

Who is this for: Facility managers, electrical contractors, and office planners who need an economical, easy-to-install occupancy sensor for open office or cubicle environments. The Sensor Switch CM PDT 10 is suited to spaces where seated occupants may move little but still require accurate presence detection—offering a practical balance of reliability, simple programming, and energy savings without on-site sensitivity adjustments.
