Active IR motion sensor FLEX are used to protect gangways and/or indoor and outdoor windows in protected posi-
tions with several heights and widths. They are made of 2 parts, transmitter and receiver, that have to be installed one
opposite to the other. The main feature of this model is the ability to vary the position of the optics within the RX and
TX aluminum bar. This solution also allows to modify the height of the same aluminum profile, adapted to every type
of installation.
- Transmitter and receiver controlled by 2 microprocessors.
- Transmission of 5 bit codes every 20-50 ms to avoid masking with fake transmitters.
- Optical transmission modulation at 36 KHz and opaque polycarbonate filter to avoid disturbance by natural or artifi-
cial light.
- Optical synchronization between transmitter and receiver without additional connections.
- Control of oblique rays to avoid false alarms due to insects or small objects placed between tx and rx.
- Creep zone selectable and adjustable.
- Anti-opening and magnetic anti-removal selectable.
- Alarm output by means of a solid state relay.
- LED indication of the reception quality.
- Buzzer selectable.
- All settings are selectable using dip-switches.
The 2 elements, transmitter and receiver must be installed vertically one opposite to the other with the terminals orien-
ted to the same direction.
Remove the cap, let the PCB slide fix the support cap to the wall. To access the DIP-SWITCHES and the Clamps it’s
just necessary to remove to upper caps.
Do not cover or paint the plastic housing of the items. Avoid the direct contact with rain or water jets.
Avoid, if possible, that the sunbeams reach directly the receiver, this could hinder the synchronization.
If the normal security precautions should not be enough, it is possible to use the anti-removal device: for the instal-
lation it is necessary to fix the magnet in the wall at the height of the magnetic contact (31,5 cm from the plug at the
terminals side of the item). The contact connected to the circuit transmits the tamper signal if it is separate from the
magnet in the wall. The system also has anti-opening tampers for the plugs..***. For the usage mount the apposite
springs on the TAMPER microswitch (fig. 1 fig.2).
The system generates an alarm in case of power failure or any wire tearing.
