QX Infinity Series

Masking strips are supplied with the QXI in the box. You can mask individual sections of the detection area by placing the corresponding strip to the lens. The latches that hold the lens in place can be found at the top, bottom, left and right of the lens. The lens can be removed easily by unlocking each latch with your thumb or screwdriver and gently push the lens out. Please ensure that you place the masking strips on the inside of the lens, not on the outside.

The battery-operated models of the QXI (QXI-R, QXI-RDT) have back-boxes that are large enough to accommodate most transmitters. The maximum size of the transmitters should be: 90mm (length) x 50mm (width) x 30mm (depth). The backbox of the QXI have sticking mounting pads inside to secure the transmitter in place.

Anti-blocking is a feature for the QXI-DT in multi-level mode only. Anti-blocking is used when the detector suspects that it is being blocked by a person or object and will trigger the trouble output. The logic steps are as follows:

1. PIR detects first
2. Microwave then receives strong signal within 10-30 seconds of the first PIR detection
3. No PIR detection within 10-30 seconds
4. Trouble signal is generated

The QXI is in multi-level mode by default which accommodates mounting heights between 2.2m – 2.7m. Low mount is for the pet alley function which can be achieved by removing the main unit from the backbox and gently flipping the mirror into the horizontal position. Be aware to not touch the mirror face, only the sides. The mounting height for the pet alley pattern is 0.8m – 1.2m. If the QXI is mounted higher than this and is in the pet alley pattern, that human detection may be compromised. Please note, anti-blocking feature is not available when the QXI is in pet alley mode.
