Sensor Switch CMR 10 Contractor Select

The Sensor Switch CMR 10 is a line-voltage ceiling-mounted occupancy sensor designed for commercial spaces. It offers full 360° PIR (Passive Infrared) detection and is optimized to monitor larger motion patterns within a 24-foot radial range when installed at a typical ceiling height of 9 feet. Compatible with ceiling tiles, metallic grids, and common electrical boxes, it includes mounting hardware for quick installation. This model is suited for monitoring private offices or small rooms with reliable, hands-off control over lighting. Notable for large-motion detection, it provides robust coverage while maintaining straightforward wiring and setup.
Leviton PIR Ceiling Mount Occupancy Sensor

This Leviton sensor provides a cost-effective option for commercial and institutional installations where recessed ceiling units are impractical. It uses Passive Infrared (PIR) technology with a segmented Fresnel lens to monitor occupancy. The unit combines the sensor and switching relay in one package, which can reduce labor and material needs during installation. Its design prioritizes straightforward deployment, making it suitable for spaces where quick retrofits are desirable while preserving reliable occupancy-based lighting control.
Maxxima Ceiling Mount 360° PIR Occupancy Sensor

The Maxxima ceiling mount sensor delivers 360° PIR coverage for both commercial and residential use. It is hard-wired and compatible with LED lighting, among others, with a maximum mounting height up to 15 feet. It supports a broad load range and emphasizes compatibility with various lighting technologies, offering a practical balance of broad coverage and straightforward installation. The design aims at energy savings through reliable presence detection and automatic lighting control in larger rooms or open-plan spaces.
Intermatic IOS-CMP-LV Commercial Grade Low-Voltage Sensor

The Intermatic IOS-CMP-LV is designed for low-voltage systems, offering PIR-based occupancy sensing in a compact, white unit. It includes an ambient light sensor and a time-delay off function, allowing for flexible lighting control in commercial environments. The sensor is suitable where a low-voltage control signal is preferred or required, helping to simplify wiring while maintaining reliable occupancy detection and user-adjustable off timings.
Leviton O3C10-MDW ODC Series Vacancy Sensor

The Leviton O3C10-MDW is a multi-technology ceiling-mount vacancy sensor designed for spaces up to 1,000 square feet. It supports 120-277 volt operation and provides automatic adjustment features to align with occupancy patterns. The device emphasizes energy savings through an exclusive walk-through feature, ensuring lights do not remain on unnecessarily after short occupancy. This sensor suits open office areas or large rooms where precise timing and adaptive responses improve efficiency.
Buying Guide
- Coverage area and mounting height: Ceiling-mounted sensors vary in detection radius. Check if the unit supports your room size and typical ceiling height to avoid gaps or false triggers.
- Voltage compatibility: Choose a sensor that matches your electrical system (120-277V vs low-voltage options). Ensure compatibility with existing wiring and ballast types for lighting.
- Detection technology: PIR sensors are common and reliable for occupancy, but consider ambient light sensing if you want lights to adjust based on daylight.
- Time delay and sensitivity: Look for adjustable delay settings so lights stay on long enough for typical activity but don’t remain on after occupancy ends. Some models offer auto-adapting or walk-through features for extra savings.
- Ease of installation: If you’re retrofitting, models with simple mounting options and integrated relays reduce installation complexity and labor costs.
- Ambient conditions: For damp, dusty, or high-traffic areas, select sensors rated for commercial-grade durability and appropriate ingress protection.
- Multi-technology options: In larger spaces, a sensor that supports multiple lighting technologies (LED, CFL, incandescent) may simplify compatibility with existing fixtures.
- Wiring requirements: Some sensors require a neutral wire for operation; confirm your wiring setup before purchasing.
- Maintenance and firmware: Check for potential firmware updates or user-replaceable components, especially for long-term reliability in commercial settings.
- Warranty and support: Favor brands with solid warranties and readily available technical support for troubleshooting and replacements.
When selecting a ceiling mount vacancy sensor, balance coverage, compatibility, and ease of installation with your budget and energy goals. For office spaces, prioritize adaptive timing and walk-through features; for retail or educational environments, ensure reliable ambient sensing and fast installation to minimize downtime.
