The REM is a safety sensor for automatic swing doors based on active infrared technology. It secures the moving door leaf.
To do so, the modules must be installed on the top rail on both sides of the door leaf.

TEST OUPTUT***
The transmitter (TX) should be placed next to
the door edges that need to be protected.
The angle adjustment clip should be next to
the transmitter.
Turn the module if necessary.
When a module needs to be turned:
1. detach the clips
2. turn them by 180°
3. reattach
NO POWER
NO DETECTION
DETECTION
The module connected to the door controller
becomes the MASTER.
Plug the SLAVE
CABLE between
the modules in
one of the two
placements.
Mount the profiles as close as possible to the closing edge. Leave 2 cm
for the black end caps. Take the position of the white clips into account
before drilling and fastening the screws.
* Output status when sensor is operational
** For compliance with EN 16005 and DIN 18650, connection to door controller test output is required.
*** If door controller is not tested: conncect BLUE to 0 V and RED to +12 V - 30 V DC.
To loosen the modules, please use
a screwdriver.

CALIBRATION
IMPORTANT: Test the good
functioning of the installation
before leaving the premises.
If necessary, position spots
closer to or away from the door
and relaunch a calibration.
After changing a DIP-switch, the orange LED flashes.
A LONG push on the push button of the MASTER
confirms the settings of ALL MODULES.
Afterwards, a number of green flashes (x) indicates
the number of connected modules.
A SHORT push on the button of the MASTER launches a
calibration on ALL MODULES.
Do not stand in the detection field!
When the LED is off on all modules, the detection zone is OK.
The detection zone is too short:
turn the screw clockwise.
The detection zone is too long:
turn the screw anticlockwise.
Step out of the detection field.
If necessary, change angle or switch off background (DIP 3 = OFF).
Launch a new calibration.
The flashing speed of
the LED increases when
approaching the optimal
position.

- The device cannot be used for purposes other than its intended use. All other uses cannot be guaranteed by the manufacturer of the sensor.
- The manufacturer of the door system is responsible for carrying out a risk assessment and installing the sensor and the door system in compliance
with applicable national and international regulations and standards on door safety.
- The manufacturer of the sensor cannot be held responsible for incorrect installations or inappropriate adjustments of the sensor.
- Only trained and qualified personnel may install and setup the sensor.
- The warranty is invalid if unauthorized repairs are made or attempted by unauthorized personnel.
LED-SIGNALS
The ORANGE LED
flashes 1 x
every 3 seconds.
Bad calibration
The ORANGE LED is
on permanently.
The ORANGE LED
flashes quickly.
The RED or GREEN
LED is ON sporadicly
or permanently.
Launch a calibration.
Send the sensor back for a technical check-up.
Corfirm the DIP-switch setting:
long push on the push button.
Cut and restore power supply.
If orange LED flashes again, replace sensor.
The sensor does not
react, but a calibration
can be launched.
Chech wiring.
- Door control with test:
Connect RED and BLUE wires to test output.
- Door control without test:
Connect BLUE to 0 V and RED to +12 V - 30 V DC.
