3.3 Connection to the Control Panel
3.3.1 Alarm contacts: Alarm, Tamper, Fault
On transmitter and receiver PCB are present 3 relays. These Relays are static with dry contacts
normally closed.
By means of these contacts it’s possible to communicate to the control panel
the following conditions:
ALARM, TAMPER, FAULT
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 made by
Static Relays with maximum current of 100 mA.
Remark:
in closed condition the resistance of these contact is about 40 ohm.
The connections to control panel must be made by means of shielded cables.
The relays are activated for the following reasons:
- ALARM RELAYS
1- Stopped target alarm on receiver
( Remark1 )
2- Intrusion alarm on receiver
3- Receiver masking condition alarm
4- Alarm of external detector connected at Auxiliary Balanced Line
5- Successful result of test procedure operation on receiver
6- Insufficient received signal (V RAG >6,99V)
7- Channel alarm.
- TAMPER RELAYS
1- Cover removing (radome) (TX and RX)
2- Tilt Bulb position (TX and RX)
3- Tampering of external detector connected at Auxiliary Balanced Line
4- Cut of Auxiliary Balanced Line
5- Short circuit of Auxiliary Balanced Line.
- 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- Fault of external detector connected at Auxiliary Balanced Line
6- RF (radio frequency) or BF (low frequency) Oscillator fault on Transmitter
7- Mains missing or power supply fault (more then 3 hours)
Remark 1:
if the intrusion signal, after overcoming the pre-alarm threshold, stays for 40 sec
between pre-alarm
and alarm threshold, the barrier gives a “Stopped target alarm”
event, and the alarm output is activate (the contact become opened).
