Volumetrics are in a way the eyes and ears of your alarm system. There are several different detection techniques: Passive infrared detector (PIR): this type of detector senses all warm body movements. The detector transmit infrared rays and triggers the alarm when one or more of these beams are broken. • Hyperfrequency: this detection technique is the most efficient. An hyperfrequency sensor can pick up, using radar waves, any moving body whether cold or hot. • Double technology detectors, thus called because they combine radar hyperfrequencies and PIRs.
High tech. detector, the BIVO8 is designed to protect dwellings and small shops. The combination of hyperfrequencies and PIR eliminates all risk of false alarms. Adjustable hyperfrequency range and infrared pulse count makes the BIVO8 very reliable. 2 LEDs give status and simplify adjustments. A temperature compensation system (by thermistance) makes it additionally reliable. Surveillance can be carried out up at a distance of 8m. Hyperfrequency: 10,595GHz. Anti tamper and alarm outputs on NC contacts. HONEYWELL DT-7225 Dual-PIR-MW-Intelligence-Detector
