DS950 Series High-performance PIR Motion Detector

The DS950 and DS970 Detectors provide excellent catch performance and freedom from false alarms with five layers of detection (including look-down zone), patented passive infrared, and microwave processing.

Features

• Five layers of detection including look-down zone
• Supervised microwave and PIR
• Anti-masking feature
• Selectable PIR sensitivity
• Five mounting options
• Draft and insect immunity
• Motion Monitor supervision
• Alarm memory
• Microwave Inhibit

Functions

• Signal Processing - Uses passive infrared and microwave technologies to provide an alarm condition upon simultaneous activation of both fields of protection. Adjustable PIR and microwave sensitivity.
  • PIR Signal Processing: Motion Analyzer II uses multiple thresholds and timing windows to analyze timing, amplitude, duration, and polarity of signals to make an alarm decision. It will not alarm on extreme levels of thermal and illumination disturbances (heaters and air conditioners, hot and cold drafts, sunlight, lightning, and moving headlights). Motion Analyzer II provides two sensitivity settings.
  • Microwave Signal Processing: Pattern recognition circuitry identifies and ignores repetitive false alarm sources. Adaptive processing adjusts to background disturbances.
• Microwave Anti-Masking - Provides supervision trouble signal if microwave reflective material is placed within 30.5 cm (1 ft) of detector.
• Test Features - Three-color alarm LED with separate colors for alarm, PIR, and microwave activation. Internal noise voltage test pins provide pattern location and background disturbance evaluation using a standard analog meter. Trouble memory feature recalls trouble conditions.
• Supervised Microwave and PIR - Patented fully supervised microwave and PIR circuitry provides single technology coverage in the event the microwave subsystem fails.
• Draft and Insect Immunity - The sealed optic chamber provides immunity to drafts and insects.
• Alarm memory - Provides indication of stored alarms for use in multiple unit applications by latching the alarm LED. Controlled by a switched voltage from the control panel.
• Microwave Inhibit - When using the memory input, the microwave portion of the detector can be turned off during disarm period.
• Motion Monitor - Switch-selectable one or 30 day Motion Monitor supervision timers provide the detector with the ability to verify that there is a clear view of the protection area. The memory circuit can also control this feature.
