DS939 360 Degree PIR Ceiling Mount Detector
The DS939 is a panoramic PIR ceiling-mount detector with up to 16.4 m 360 degree coverage under the CCC coverage condition. It uses First Step Processing and adjustable PIR sections to support coverage integrity across different mounting heights.
The detector suits ceiling-mounted indoor intrusion detection where broad panoramic coverage is needed from a single unit. Hinged mounting, high-efficiency walk-test indication, alarm memory and remote LED walk-test control support practical installation and maintenance.
