3 - PRELIMINARY CHECKS
4.1 - Settings
WARNING - before installing the product, perform the following
checks and inspections:
- Check that the intended mounting surface is solid and does not
allow vibrations
- Use electrical connections suitable for the currents required
- Check that the power supply conforms to the values in the techni
-
cal specifications
- Ensure that all the material used for installation complies with the
relevant regulatory standards
It is possible to associate up to a maximum of 4 transmitters (4 dif-
ferent edges) to each relay. For this reason, to each receiver can be
associated a maximum of 8 transmitters.
Warning: for a correct functioning of the system, every
transmitter part must have the frequency dip put on the same
way of the correspondent receiver part.
In order to avoid any interferences on installations which need a
higher number than 4 security channels it is advisable to distin-
guish the frequencies utilized among the various receivers and their
transmitters associated transmitters.
4 - INSTALLING THE PRODUCT
Phase Description
1
Connect the sensitive edge to the terminal boards of the transmitter inserting the 8,2KΩ ¼ of Watt in series only in case clean
contact N.C. mechanical edge are utilized (see page 1). Orientate and put the device as explained in figure.
If the 8,2KΩ ¼ of Watt is not connected (with mechanical edge) the system does not work and enters in alarm.
2
Set the dip switch relative to the utilized frequency (dip 3 and dip 4) which will have to correspond to the one of the receiver.
3
Give power to the system connecting the two batteries AA – 1,5 V to the battery holder. Pay attention to the polarity.
4
Fix the device as much higher than possible in such a way as there are no obstacles on the direction of the receiver and in
such a way as the maximum distance between the two devices is less than 15 meters. (max 20 meters).
