Please Note: The DSC WLS914-433 wireless motion detector has been discontinued and replaced by the WS4904P model number.

DSC WLS914-433 Product Description:


The DSC WLS914-433 is a specialized wireless passive infrared (PIR) motion detector using (2) dual-element PIRs. The WLS914-433 utilizes 2 PIRs that are horizontally and vertically separated and the (2) lens system produces an overall pattern that is similar to a checkerboard. Both PIR detectors must be tripped at the same time in order to cause an alarm, which provides pet immunity for animals up to 85 lbs.

Multi-Level Signal Processing (MLSP), temperature compensation and the large multi-beam lens design means the human target will not slip by unnoticed even on a hot summer day. The WLS914-433 wireless motion detector has a built-in 6-second delay before it will transmit a violation. This is designed to allow a door window contact time to send a signal to start entry delay to prevent false alarms. This delay cannot be changed.

Product Features:

  • Provides pet-immunity up to 85 lbs

DSC WLS914-433 Product Mounting:


Each motion detector should be located so that it provides optimal coverage of the area to be protected. When selecting locations for motion detectors, observe the following:
  • The mounting height should be 7.5 ft./ 2.3 m.
  • Do not aim the detector at a stairway which a pet has access to. Do not place objects that pets can climb on higher than 3 ft (0.9m) closer than 6 ft (1.8m) to the detector (e.g. a cat on a couch).
  • Do not aim the detector at reflective surfaces such as mirrors or windows. This may distort the coverage pattern or reflect sunlight directly onto the detector. Avoid locations where the detector may be exposed to direct or reflected sunlight.
  • Avoid locations that are subject to direct air flow, such as near an air duct outlet.
  • Do not locate the detector near sources of steam or oil vapor, such as a stove or fryer.
  • Do not obscure the detector's coverage pattern with large objects within the detection area. If you can't see the detector, it can't see you.
  • For indoor use only
  • Dead zone 6" (15 cm)
