3.3 Connections to the Control Panel
3.3.1 Alarm contacts: Alarm, Tamper, Fault
On the transmitter PCB there are 2 relays and on the receiver PCB there are 3 relays. These
relays are normally closed, static dry contacts. Using these contacts it is possible to interface
the following status to the control panel:
•
ALARM (RX)
•
TAMPER (RX and TX)
•
FAULT (RX and TX)
There are also 3 inputs to activate the following functions:
•
Test (TX and RX)
•
Stand-by (TX and RX)
•
Synchronism (only TX)
The output contacts for alarm, tamper and fault, both on transmitter and receiver, are static relays
with maximum current of 100 mA.
Remark:
in closed condition the resistance of these contacts is about 40 ohm.
The connections to control panel must be made using shielded cables.
The relays are activated for the following reasons:
- ALARM RELAYS
1- Intrusion alarm on receiver
2- Receiver masking condition alarm
3- Successful result of test procedure operation on receiver
4- Insufficient received signal (V RAG >6,99V)
5- Channel alarm
( Remark1 )
- TAMPER RELAYS
1- Removal of Cover (radome) (TX and RX)
2- Tilt Switch position (TX and RX)
- FAULT RELAYS
1- Battery voltage low (< +11V )
2- Battery voltage high (> +14.8V )
3- Temperature low (< -35°C internal)
4- Temperature high (> +75°C internal)
5- RF (radio frequency) or BF (low frequency) Oscillator fault on Transmitter
Remark1:
if transmitter is set-up on channel F, the alarm won’t be given.
