VT530 / IR access sensor

This page is being updated from 07th December 2020 till 10th of December 2020. Until then, all information on this page is incorrect or insufficient.

Function and purpose

For installation inside of IT racks and cabinets. Sensor controls status of door or window: open, closed.

Safety Instructions

Regularly check that the IR sensor is not covered with dust.
Do not expose the IR sensor to direct sunlight.
Make sure that you do not scratch the IR sensor during installation and operation.

Package includes

The optical access sensor consists of:

Converter inside of a compact plastic housing
IR sensor
Bracket for mounting of both the converter and the IR sensor
Bolts, screws and nuts
RJ11 two meter cable
Sticker

Connecting optical access sensor

Connect IR sensor using RJ9 (4p4c) jack to 4 pin jack of "VT531 / Optical access sensor".
Connect one end of RJ11 / RJ12 cable to the monitoring unit into any analog ports (A1...A8) and to RJ12 port of "VT531 / Optical access sensor".
Put a sticker on the door opposite of IR sensor. Min. distance is 10 mm, max. distance is 35 mm.
Access sensor will appear automatically in a System tree.

Adjusting sensor sensetivity and LED indication

Adjusting sensetivity

Use flat-head screwdriver to adjust the sensor sensetivity.

Turning the screwdriver clock-wise will increase view distance up to 3 - 4 cm.

Turning the screwdriver counterclock-wise will decrease the view distance down to 1 cm.

It is possible to decrease view distance of the sensor below 10mm, but only if the sticker is bend in a spherical shape. This is because IR sensor uses two beams which require some distance to work properly.

LED indication

The sensor has red LED sticking out on top of the sensor. By default the sensor is configured to:

If the door is closed, red light is Off.
If the door is open, red light is On.
