Single balancing
Single zones can discriminate 3 conditions on the
entire terminal:
•
standby
•
alarm
•
tamper (short-circuit)
For each of these, the SmartLink reads different
resistance values on the terminal, expressed below
in Ohm.
4-8-3
Double balancing
Double balancing discriminates 4 distinct conditions
on the zone terminal:
•
standby
•
alarm
•
tamper (short-circuit)
•
tamper (wire cutting)
For each of these, the SmartLink reads different
resistance values on the terminal, expressed below in
Ohm.
