MAKS PIR Combi (VB) – is a combined wireless motion detector and acoustic glass break sensor. The device is equipped with a PIR-sensor, the Vertical Barrier lens with a narrow horizontal viewing angle and microphone. Device designed to control the perimeter inside the room, to protect glass structures, windows, doors, garage doors, etc.

When the thermal balance of the environment changes or there is the sound of breaking glass, the device sends an alarm notification to the MAKS PRO control panel. For indoor use only.

Vertical Barrier Lens:

The Vertical Barrier lens has a narrow horizontal viewing angle. Detectors equipped such lens are used to control the perimeter inside the room, to protect glass structures, windows, doors, garage doors, etc. 

Protection against false positives:

Acoustic data processing based on modified speech recognition algorithm. Sensor analyses the sequence of the thud and the ringing sound of falling glass. 

Types of glass:

Ordinary, patterned, tempered, laminated, reinforced, protected by polymer film of classes A1, A2, A3, double-glazed windows 4x16x4.

Radio Communication:

The detector transmitter operates in several channels of 868.0 to 868.6 MHz band for reliability. Secure two-way radio communication. Distance – up to 4800m in line of sight. Three grades of power, maximum – up to 20 mW.


The detector is connected to the MAKS PRO control panel and is configured using the MAKS SETUP mobile application.
