For installation inside of IT racks and cabinets. Sensor controls the status of door or window: open, closed.
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.
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
Connect IR sensor using RJ9 (4p4c) jack to 4 pin jack of "VT531 / Optical access sensor".
Connect one end of the RJ11 / RJ12 cable to the monitoring unit into any analog ports (A1...A8) and to the 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.
The access sensor will appear automatically in a System tree.
Use the flat-head screwdriver to adjust the sensor sensitivity.
Turning the screwdriver clockwise will increase the view distance up to 3 - 4 cm.
Turning the screwdriver counterclockwise will decrease the view distance down to 1 cm.
It is possible to decrease the view distance of the sensor below 10mm, but only if the sticker is bent in a spherical shape. This is because the IR sensor uses two beams which require some distance to work properly. |
The sensor has a red LED sticking out on top of the sensor. By default, the sensor is configured to:
If the door is closed, the red light is Off.
If the door is open, the red light is On.
Mounting bracket is supplied with each "VT531 / Optical access sensor".

Bracket steel thickness is 0.8 mm. Below You can find how users can mount the "VT531 / Optical access sensor" with such a bracket.
Example 1
The bracket is mounted to two captive nuts using two M6 bolts. Pliers used for fitting. VT531 plastic case is mounted onto the bracket using M4 bolts and M4 nuts. IR sensor is mounted using two M2x10 bolts and two M2 nuts. IR sensor is pointing towards the door.
Example 2
The bracket is mounted to the rack using two 4.8*13 screws. Pliers used for fitting. VT531 plastic case is mounted onto the bracket using M4 bolts and M4 nuts. IR sensor is mounted using two M2x10 bolts and two M2 nuts. IR sensor is pointing towards the door.
Example 3
The bracket is glued to the rack using a sticker. Pliers used for fitting. IR sensor is pointing towards the door. The door is opened in a current case.
