Anti-burglary protection in EX zones

Anti-burglary protection in potentially EX zones requires the use of certified intrinsically safe PiR motion sensors. A comprehensive ATEX-compliant solution that has gone through stringent ATEX certification process 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.

MM 1007 Ex (XDH10TT-AM/Ex) MMG Intrinsically Safe PIR+MW Detector

The XD10TTAM/Ex Detector (MM 1007 Ex) is a combined detector consisting of three detection technologies. It uses two PIR sensors and one microwave detector. The range of the microwave detector is adjustable from 0 m to 15 m, while the PIR range is fixed at 10 m. The detection range can be adjusted by changing the microwave detection range.
In factory mode, the detector is configured for installation at a height of 2,4 m. It provides volumetric area coverage. The factory settings include the elimination of false alarms caused by animals up to 10 kg.
The XD10TTAM lenses are manufactured to high standards and are coated with a durable ultraviolet filter, ensuring protection against UV radiation.
The detector is adapted for use in areas with the risk of explosion of gases and vapors. Power supply must be provided from an intrinsically safe source, and the output contacts for alarm and tamper must be separated by a barrier – an intrinsically safe relay.
For a larger number of detectors, it is possible to use a single more powerful power supply with a maximum safe output voltage of Ui = 16,8 V.

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.
