Anti-burglary protection in EX zones

Anti-burglary protection in potentially explosive areas requires the use of certified intrinsically safe PiR motion sensors. A comprehensive ATEX-compliant solution is a set consisting of intrinsically safe PiR detectors or dual PiR + MW dectors powered by an intrinsically safe MM 2012 power supply . The alarm and tamper line is protected by a two-channel relay separator type MM5016.

Intrinsically safe motion detectors are also used in lighting control systems in potentially explosive areas. In addition to the intrinsically safe power supply, the set includes a single-channel MM5011 separator.

Intrinsic safe PIR + MW detector

DESCRIPTION:
Viewguard detectors analyse the type of incoming signal using an integrated microprocessor. The decision to trigger an alarm is based on an analysis of the strength of the detected signal. Viewguard detectors respond to an incoming signal ultimately fast and are resistant to trigger a false alarm due to poor signal quality, at the same time, they keep an eye on whether an intruder is trying to deceive the sensor. The unique multi-stage signal strength measurement makes Viewguard detectors the best motion detection system. Thanks to efficient power management, the current consumption of the Viewguard motion detector is one of the lowest of any motion detector on the market.
That quality allows Viewguard to be installed where a large number of detectors need to be connected on a single power loop. The detectors are designed to use in commercial and industrial environments.
