interfere with reception/transmission efficiency.
4_ Close the card housing with the appropriate cover (4 in fig. 1).
OPERATION
- It is possible to connect up to 4 TWC slave devices to the master TWM (every device is associ
-
ated to one of the 4 positions, indicated by 4 green leds on the master device) .
- Through dip-switches you can select up to 8 different radio channels and install more TWM
devices in the same area.
- Each TWC sensor has two inputs associated with the two relay outputs in the TWM, ie the
TWC input M1 communicates with the TWM output 1 (terminals 5 and 6) and the TWC input
M2 communicates with TWM output 2 (terminals 7 and 8). Output 1 of the TWM can have a
normally closed or normally closed contact 8K2 resistive selectable via P4, while output 2 can
have a normally closed contact.
- The connection between a TWC device and the master TWM is indicated by a permanent
green led on the master TWM.
- In case of a communication failure between the master TCM and the slave TWC devices and/
or when batteries are low, the relevant green led will flash quickly. Exit contacts will be open.

NOTE: to use the TWC sensor with resistive sensitive edges, firstly put the J4 jumper of
the TWC for M1 contact input, or the J2 jumper of the TWC for the M2 contact input
(see figs. 4 - 5). If you need to change the type, you must reprogram after changing the
position of the jumpers.
