Ivory wall-mounted occupancy sensor with PIR and microwave detection

Acuity Sensor Switch

Acuity Sensor Switch LWS PDT IV Occupancy Sensor 1200 sq ft Ivory

SKU CH-Q9W9-D8CZA

Occupancy sensor with PIR and microphonic detection covering 1200 sq ft, hard-wired for 120V or 277V AC with adjustable 30-second to 20-minute delay

  • Dual PIR and microphonic detection covers 1200 sq ft
  • Hard-wired 120V or 277V AC suits commercial installs
  • Adjustable 30 sec to 20 min timeout saves energy
  • Ivory finish blends with standard wall plates
  • Wall-switch box mount simplifies retrofit installation

Motion-sensing wall switch

The Acuity Sensor Switch LWS PDT IV mounts in a standard wall-switch box and combines passive infrared with microphonic detection to cover 1200 sq ft at the suggested height. It operates on 120V AC or 277V AC and is finished in ivory. New condition.

Dual-technology detection

Microphonic sensing adds sound-based occupancy awareness to the infrared field, so the unit can trigger lighting or alarm circuits even when direct line of sight is partially blocked. The hard-wired communication method means no wireless pairing or batteries are required for operation.

Fixed time-delay range

The adjustable time delay runs from 30 seconds to 20 minutes and cannot be set outside that window. Installers needing shorter or longer hold times must choose a different device. Coverage assumes the suggested mounting height; lower or higher placement will change the effective area.

Questions about this item

How often will the passive infrared and microphonic sensing elements need cleaning or replacement?

The sensor uses passive infrared and microphonic technology with no user-serviceable parts; typical maintenance is limited to keeping the lens free of dust or paint.

What coverage limit is reached first when the sensor runs continuously in a large space?

The unit covers up to 1,200 sq ft at the suggested mounting height; beyond that area a second sensor is required.

How much heat or power draw should I expect when the device operates all day on a 120V AC circuit?

It runs on 120V AC or 277V AC hard-wired power with no fan; heat output is negligible and power draw is limited to the internal sensing circuitry.
