• The mounting height must not exceed 2.40 m (3 m in
preparation).
Table 1: Dimensions depending on door height
• The door-to-IRMA 6 distance must not exceed 20 cm if the
installation height is less than 2 m.
Door height Covered door width Distance max
• The inclination angle of IRMA 6 must not exceed 5°. 1.90 m 1.50 m 20 cm
For the relation between maximal distance
(door – sensor), counting width and the door height see Table 1,
p. 4.
These values are standard values. In many cases wider ranges can
be covered. Please consult [e-mail].

Needed Tools
Drilling machine
with twist drill (10 mm)
Jig saw Hex Key
size 4 mm
Most relevant steps at a glance Essential directives for installation
1. Prepare needed tools and drilling templates, IRMA 6 sensors as well as
cables for doors to be equipped.
2. Install IRMA 6 into vehicle doors panels and connect IRMA 6 via Ethernet
to data transmission, to power supply and (optionally) to door contacts.
3. Configure IRMA 6 via web interface, while using RJ 45 service cable and
ETH interface.
4. Perform a commissioning test on your pc or on-board computer.
•In all considerations with regard to installation positions and orientation, it is
assumed that the observer is inside the vehicle.
•The sensor-to-door distance must not exceed 20 cm if the installation height is less
than 2 m, see Table 1, p. 4.
•Install IRMA 6 on a horizontal surface. The maximum permissible deviation from the
horizontal plane is ±5°.
•IRMA 6 must be installed by staff that follows the pertinent regulations and the
installation manual.

Tighten screws with hex key
Max. 3 Nm Max. 3 Nm
Tighten both screws max. 3 Nm with a hex key (4 mm) on the interface unit.For easy and correct connection to the cables: Align the M12 connector so that the stop lug is
centered toward the top of the labels!
Connect IRMA 6
Connect IRMA 6 via (angled) M12 connectors to the Ethernet
network, to voltage supply and optionally to the door contacts.
Angled M12 connectors, slewable (180°), optionally available.

In a 2-doors scenario, the door contact signal is connected only to the master sensor.
The master sensor is identified in the following way:
Standing inside the vehicle, view from inside to the outside – the left sensor is the master sensor, the right sensor is the slave sensor.
