OPTEX QX Infinity Series

Product Profile

Early detection with high mount sensors

OPTEX’s core philosophy is to detect intrusion before individuals break into the property or building. Early warning and detection is the best way to prevent crime and QX Infinity series complements OPTEX’s extensive choice of short-range outdoor PIRs by bringing a family of compact outdoor detectors – PIR and dual-technology - providing 12m detection area, up to 120° in width. A particular benefit of this series is that the sensors are specifically designed to be installed at heights of up to 2.7m, discreetly fitting into any residential or commercial buildings while keeping safe out of the reach from vandals.

Detection analysis to filter out false alarms

The new Quad technology features a pyro element that has been redefined by OPTEX and supports a greater performance with a double layered detection in a compact design. The QXI series features improved Super Multi-Dimensional Analysis (SMDA) logic and Double Conductive Shielding for even more reliable sensing capabilities and greater tolerance against light and RFI. It allows for greater immunity against pets and can also be installed as a low mount PIR detector to create a ‘pet alley’ and further reduce the likelihood of nuisance alarms.

Compact design and easy installation

Installing the sensor has been made simple with an easy to open/close front cover. Other features include an Automatic Walk Test Mode, which automatically starts when the cover is closed and returns to normal mode after three minutes. For extra convenience, power to the wireless models can be shared through a common battery (CR123A) to the transmitter in the base of the device which can easily be swapped out/replaced when the need arises.

The QXI series includes four models:

Wired models

QXI-ST 120°, 12m, wired, standard
QXI-DT 120°, 12m, wired, dual-technology, with an anti-blocking feature to detect intruders attempting to deliberately mask the detector

Battery-operated (wireless) models

QXI-R 120°, 12m, wireless, standard
QXI-RDT 120°, 12m, wireless, dual-technology

The QXI series is the ideal solution to protect the approach to warehouse and commercial buildings, driveways, houses and gardens. The sensors will trigger both intruder alarms and CCTV.
