Bosch Long Range Tritech, Pet Immunity Detector (DS720i)

• The wall or ceiling mount DS720i TriTech® PIR and Microwave Detector covers up to 91 m (300 ft). Motion Monitor and Anti-masking protection provides coverage integrity. Field replaceable mirrored optics and three different coverage patterns provide installation flexibility.• Indicates stored alarms for use in multiple unit
  applications by latching the alarm LED.
  • Controlled by a switched voltage from the control
  panel.
• Signal Processing
  Uses passive infrared and microwave technologies to provide an alarm condition when both fields of protection are simultaneously activated.
•  Adjustable PIR and microwave sensitivity. PIR Signal Processing Uses Motion Analyser II multiple thresholds and timing windows to analyse timing, amplitude, duration, and polarity of signals to make an alarm decision. Will not alarm on extreme levels of thermal and illumination disturbances caused by heaters and air conditioners, hot and cold drafts, sunlight, lightning, and moving headlights.
• Two sensitivity settings are provided. Microwave Signal Uses pattern recognition circuitry to identify and ignore repetitive false alarm sources.
• Adaptive processing adjusts to background disturbances to reduce false alarms while maintaining catch performance. Test Features High efficiency walk test LED is visible throughout the coverage pattern (reducing installation time).
• LED flashes to indicate a trouble condition. Internal noise voltage test pins use standard analogue meter to provide precise pattern location and background disturbance evaluation. Separate test LEDs for PIR and microwave activation. Alarm LED can be controlled remotely. Supervised Microwave and PIR Patented fully supervised microwave and PIR circuitry provides single technology coverage in the event the microwave subsystem fails. Use the memory circuit to force a self-test at anytime. Anti-masking With Spray Detect Selectable to provide a microwave supervision trouble signal if microwave reflective material (metal, wood, plastics) is placed within 30.5 cm (1 ft) of the detector.
• IR Anti-masking feature detects objects placed to cover the detector or sprayed on the lens area. Anti-mask sensitivity is selectable, and Anti-mask activation can be delayed to reduce false alarms. Motion Monitor Switch-selectable four or thirty day Motion Monitor supervision timers provide the detector with the ability to verify that there is a clear view of the protection area and that it has not been blocked.
