INIM SmartLink Advanced Series Installation And Programming Manual page 22

Single zones can discriminate 3 conditions on the
entire terminal:
• standby
• alarm
• tamper (short-circuit)
For each of these the SmartLinkAdv reads different
values of the equivalent resistance on the terminal,
shown below in Ohm:

Double balancing discriminates 4 distinct conditions
on the zone terminal:
• standby
• alarm
• tamper (short-circuit)
• tamper (wire cutting)
For each of these the SmartLinkAdv reads different
values of the equivalent resistance on the terminal,
shown below in Ohm:
