3.3 Connection to the Control Panel
3.3.1 Alarm contacts: Alarm, Tamper, Fault
On transmitter PCB are present 2 relays and on 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 (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 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- Pre-alarm on receiver ( Remark1 )
2- Intrusion alarm on receiver
3- Receiver masking condition alarm
4- Successful result of test procedure operation on receiver
5- Insufficient received signal (V RAG >6,99V)
6- Channel alarm.
- TAMPER RELAYS
1- Cover removing (radome) (TX and RX)
2- Tilt Bulb 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
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 “pre-alarm” event, and
the alarm output is activate (the contact become opened).
