TOPGREENER TDOS5-JD Dual Load Motion Sensor Switch
The TOPGREENER TDOS5-JD provides two independent loads from a single unit with a single-pole configuration. It uses a Passive Infrared (PIR) sensor with a 180° field of view and a maximum detection distance of 40 feet in front and 20 feet to the sides. The unit supports occupancy and vacancy modes and requires a ground wire but no neutral. A notable feature is the walk-through function: lights turn off after 2 1/2 minutes if no motion is detected, with a 30-second window before re-triggering. This makes it suitable for bathrooms, kitchens, or garages where space-sharing or quick occupant changes occur. The dual-load capability helps manage both lighting and fans where present, enabling straightforward automation and energy savings.
Installation considerations include ensuring a grounded circuit and compatible load types (up to 150W LED/CFL per channel). The device’s advanced PIR helps minimize false triggers from non-qualifying movement, improving reliability in busy rooms. Its compact design makes it compatible with standard single-gang boxes, though some wiring may require professional installation in complex circuits.
Leviton Dual-Relay, Decora PIR Wall Switch Occupancy Sensor
The Leviton Dual-Relay model uses a Decora wall switch form factor to control two separate lighting loads from a single unit. It features self-adjusting occupancy sensor technology with automatic walk-through sensing and provides options suitable for versatile installations, including conference rooms or classrooms. The device emphasizes adaptive performance to reduce unnecessary lighting usage while maintaining prompt illumination when motion is detected. The dual-relay design is ideal for multi-area spaces with separate lighting zones, and Leviton’s firmware-enabled approach helps managers tailor lighting behavior across diverse environments.
Pass & Seymour Multi-Way Dual Technology Occupancy Sensor
Pass & Seymour’s multi-way dual technology occupancy sensor offers a single-relay design with zero-crossing for long relay life. The vandal-resistant lens delivers precise coverage while defending against tampering in high-traffic areas. A selectable walk-through mode turns lights off three minutes after the initial occupancy if no further motion is detected, ideal for hallways and storage rooms. While primarily a single-relay unit, its robust construction and dependable sensing are beneficial for spaces where unobtrusive, reliable operation is essential.
Leviton Dual-Relay Decora PIR Wall Switch Occupancy Sensor
This Leviton model provides dual-load control from a single Decora-style unit with self-adjusting occupancy detection and walk-through sensing. It supports modes tailored for office or classroom environments, helping preserve energy by ensuring lights are off when rooms are unoccupied. The sensor aims to balance rapid response to movement with resistance to false triggers, making it suitable for meeting rooms, lecture halls, and shared workspaces where consistent occupancy-based lighting is important.
Watt Stopper UW-200-I Ultrasonic Dual-Relay Sensor
The Watt Stopper UW-200-I is an ultrasonic wall switch occupancy sensor with dual relays suitable for 120/277V circuits. Ultrasonic sensing provides an alternative to infrared detection, particularly in spaces where motion is limited or obscured by furniture. This model suits conference rooms, private offices, and other areas where subtle occupancy cues may be more reliable than line-of-sight PIR systems. Dual relays allow independent control of two loads, reinforcing energy savings through tailored lighting and fan control.
Buying Guide: Key Purchase Considerations
When choosing a dual relay occupancy sensor, consider the following factors to ensure optimal performance and compatibility with your space:
- Load capacity and compatibility: Verify max wattage per channel (LED/CFL or incandescent) and the number of loads supported. Some units specify 150W per channel, while others may vary. Ensure the device supports your lighting and fan loads without overloading.
- Sensor type and coverage: PIR sensors are common, offering broad coverage but can be sensitive to hot/cold surfaces. Ultrasonic sensors detect motion via sound waves and work well in cluttered rooms. Dual technology sensors combine PIR and ultrasonic/microphonics for robust detection, reducing false triggers.
- Wiring and neutral requirements: Some models require a neutral wire, while others do not. If your box lacks a neutral, choose a no-neutral design compatible with your circuit. Ground wiring is typically required.
- Mode options and settings: Walk-through mode, occupancy vs. vacancy modes, and conference/classroom presets tailor performance to your space. Look for adjustable time-out periods and sensitivity settings.
- Coverage area and mounting: Consider ceiling or wall mount options, and whether the unit fits standard boxes or gang plates. For hallways and large rooms, higher coverage models with vandal-resistant lenses may be preferable.
- Reliability and lifespan: Features like zero-crossing relay technology or self-adjusting sensors contribute to long-term reliability, reduced mechanical wear, and fewer nuisance trips.
- Ease of installation: Some devices are designed for straightforward single-pole installation, while others support complex multi-load wiring. If uncertain, consult a licensed electrician.
- Application fit: Bathrooms, kitchens, garages, offices, and conference rooms each demand different sensor behaviors. Match the product’s modes and range to the room’s traffic patterns.
In summary, dual relay occupancy sensors offer flexible, energy-saving automation by controlling two loads from one switch. When selecting a model, balance detection reliability, load compatibility, and installation practicality to fit your specific space and usage patterns. The options above cover a spectrum of sensing technologies and configurations to meet typical residential and light commercial needs.
