Ceiling Motion Detector Description:

The ceiling mount Ceiling Motion Detector provides a 70 ft panoramic coverage pattern and can be used on ceilings as high as 25 ft. In addition, with three separate PIR sections that are fully adjustable, the Ceiling Motion Detector provides coverage integrity at all mounting heights, plus the ability to customize the coverage for specific areas. The Ceiling Motion Detector uses several patented processing techniques to provide excellent catch performance with freedom from false alarms.

The pattern covers a 50ft diameter if mounted at 10ft and a 40ft diameter when mounted at 8 ft.

Compatible with hardwired panels.

Functions:

Signal Processing

Uses passive infrared technologies to provide an alarm condition when the field of protection is activated. Additionally, alarm signals must meet the signaling requirements to activate an alarm.

First Step Processing:

First Step Processing (FSP) allows virtually instant response to human targets without sacrificing false alarm immunity to other sources. By adjusting its sensitivity based upon signal amplitude, polarity, slope and timing, FSP eliminates the need for the installer to select the sensitivity level for the application. Each sensor is processed individually and both must agree there is an alarm before the alarm relay is activated.

Test Features:

• High efficiency LED and light-pipe system provide walk test indication that you can easily view from any angle and at any mounting height.
• Alarm memory feature allows detector to latch the alarm LED to aid in response.
• Remote LED walk-test control allows the LED to enable or disable using a switched input without accessing the detector.

Coverage Information:

Coverage is 360° x 21 m (70 ft) diameter when the detector mounts 3.7 to 7.6 m (12 ft to 25 ft). In addition, coverage is 15 m (50 ft) diameter when the detector mounts at 3 m (10 ft).
Coverage is 12 m (40 ft) when the detector mounts at 2.4 m (8 ft).
Pattern consists of 69 zones in 21 barriers. Each barrier consists of 11 m (35 ft) long and 1.5 m (5 ft) wide at 11 m (35 ft). The barriers group into three groups of seven barriers each. Each group has vertical adjustment for customized coverage.
