Buying Guide: What to Consider When Choosing an Explosion-Proof Occupancy Sensor
- Voltage and load compatibility: Confirm the sensor supports your lighting loads (LED, CFL, incandescent, ballast types) and the supply voltage (120V, 277V, or low-voltage 12/24V).
- Detection range and mounting: Consider ceiling height, room size, and whether you need 360° coverage or focused detection. Ceiling-mounted units work well in open areas; wall switches suit smaller spaces.
- Neutral wire requirements: Some models require a neutral; others do not. Match with your electrical box configuration and local electrical code.
- Adjustable settings: Time delays, ambient light sensing, and sensitivity affect energy savings and occupant comfort. A flexible model reduces false triggers in busy spaces.
- Installation environment: Look for UL listings or equivalent for indoor use, and ensure the device is suitable for the intended hazardous or sensitive environment if explosion-proof features are required.
- Compatibility with existing fixtures: Check if the sensor integrates with your current lighting controls, dimmers, or ballast types without needing additional modules.
- Maintenance and accessibility: Choose units with straightforward service access and clear mounting options to minimize downtime.
