Bosch Security Systems were launching the next generation of its Blue Line Motion Detectors at IFSEC 2011.
Blue Line Gen 2 features the makers say improved catch performance and more false alarm immunity. The range is compliant to EN50131-2-2 Grade 2 and independently tested.
Available in standard and pet-friendly models, the new series is suitable the company says for residential, retail and other commercial security applications. The motion detectors include the passive infrared (PIR), the Quad PIR detectors and the TriTech detectors that combine PIR and microwave technologies. What the firm calls pet-friendly models can be set to โNo Petโ to allow customers to use the same product in multiple applications, reducing inventory for dealers.
Darren Cox, Intrusion Product Manager at Bosch says: โUnlike other PIRs on the market the Pet detection can be switched on or off with the flick of a switch, so not only is the animal blocked out by the lens but also electronically. The terminal blocks are mounted at 45 degree angles and easily removable to facilitate installation still further. Should a system need updating or detectors changing for any reason, the mounting base is standard across all products in the Gen 2 range so just the front part of the two-piece enclosure can be removed and replaced. The unit can be retained in position to allow easy upgrades to more advanced detection technology.
โThe two piece enclosure is self locking further helping the installer and additional benefits include an integrated biaxial bubble level and removable terminal strip in the base which reduce mounting time to seconds,โ says Darren.
The commercial grade terminal strip is designed to prevent incorrect wiring and eliminate future service calls. A flexible mounting height allows the detectors to be positioned from 2.3m to 2.7m without adjustment, assuring no coverage gaps up to 12m away from the detector.
The detectors deliver an expanded 12x12m wall-to-wall, gap free coverage area. With First Step Processing, the detectors analyse motion to differentiate human targets from other sources of movement and automatically adjust sensitivity based on signal amplitude, polarity, slope and timing. The detectorsโ two sensors agree there is an alarm before the relay activates โ delivering a response to intruders without false alarms. The sealed optical chamber prevents drafts and insects from affecting the detector, and pet immunity distinguishes between signals caused by humans and animals. Dynamic temperature compensation also adjusts sensitivity to accurately identify intruders regardless of room conditions.
