3.3.1 Alarm contacts: Alarm, Tamper
The Alarm output is made by static Relays contacts with 100 mA 12 V max capability and total
internal resistance of 35 Ohm. The Tamper output is made of Microswitch contact and a Bulb
contact with 100 mA max capability. The outputs are activated by the following reasons:
Alarm output:
1
– Intrusion Alarm on Receiver
2
– Channel Alarm on Receiver
Tamper output:
1
– Opening of microwave head, Tx or Rx
2
– Changing head position (Bulb contact), Tx or Rx
For high ri
sk protection it’s necessary a Periodic Test for the equipements. By means for
these control panel will be able to detect tamper action.
For the Test
function activation it
wich have Ermo-Test
strument;
it’s possible to test the microwave barrier, temporary switching-
