Praesidio BUS

Outdoor volumetric detector with Triple Technology (2PIR + MW) on RS485 BUS to be used with suitable Combivox control panels. Ideal for the volumetric protection of outdoor or indoor areas as terraces, balconies, courtyards, garages, industrial buildings, etc. Its detection range guarantees a coverage of up to 15 meters for 107° (horizontal angle). Installing height: 1,20 m. Equipped with cowl bracket for front mounting with 45° angle. Anti-masking on the IR section to signal any masking attempts. Functioning check and parameter programming (MW and PIR adjustment, operating mode) through Control panel Programming software and integrated BLUETOOTH to allow a direct connection between the detector and a Smartphone with COMBI DECT APP (iOS and ANDROID). This APP permits to monitor the detection status in real time, adjust IR and MW sensitivity and program the operating parameters (AND/OR mode, LED and Buzzer control). Integrated buzzer for chime function to signal that someone is approaching to the detection area. Endowed with a particular processing algorithm that automatically optimizes the detection according to the temperature and APA function (Anti-Plant Alarm) to reduce false alarms due to moving plants. Micro-USB connector on board for firmware updates directly on the installing place. PET IMMUNITY mode.
