CORAL-S
3.3.2 Synchronism connection
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.
3.3.3 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.
3.3.4 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.
3.4 Serial Line RS-485
3.4.1 RS - 485 / 232 Network Connection Interface
A standard RS 485 serial interface is provided on both transmitter and receiver heads of the
CORAL-S barrier. The communication parameters are the following:
Mode:
Asynchronous - Half-Duplex
Baud rate:
9600 b/s
Character length:
8bit
Parity control:
No Parity
Stop bit:
1
