3.2.2 Synchronism connection
It is not necessary to synchronize TX and RX.
Synchronization between two TXs is required only in case of peculiar installations, such as: 3 or
more barriers installed between fences or walls, protection of multi-level facades or transmitters
disturbing each other.
We recommend to contact CIAS Service for assistance.
For the Synchronism operation between two Transmitters, it is necessary to interconnect the
terminals 8
“SYNC”
and 7
“GND”
of terminal block MS2 of both Transmitters.
It is also necessary to select one Transmitter as “
Master
” and the other as “
Slave
”, by means of
jumper Jp1.
Jp1 =
“IN”
position, the terminal 8 of MS2 is the
input
for an external synchronism
signal, so the Transmitter is “
Slave
”.
Jp1 =
“OUT”
position, the terminal 8 of MS2 is the
output
for the synchronism signal
internally produced, so the Transmitter is “
Master
”
Remark:
the cable connecting the two transmitters, must be shielded with the shield connected
to the hearth tap, and must be as short as possible (not more than 10 meters).
If cables longer than 10 meters are required, it is necessary to use the synchronism
repetition circuit mod. SYNC 01.
3.2.3 Stand-by connection
For the Stand-by function activation, it is necessary connect to ground the terminal 5
“STBY” of
MS2 terminal block of the transmitter circuit.
Remark:
the Stand-by command, inhibits the MW emission of the Tx head, then an alarm is
activated on the receiver head.
3.2.4 Test connection
The Test function will be activated connecting to ground the terminal
6 “TEST”
of the terminal
block MS2 on Transmitter circuit. If the test procedure is successful done, the alarm relays on
Receiver circuit will be activated later 10 second.
Remark:
for high risk protections
it‟s necessary to perform a Periodic Test of the detectors. In
this way the control panel will be able to detect elusion actions against detectors.
