Installation and programming manual
Double zones without EOL resistor can discriminate 5
conditions on the entire terminal:
• standby on both zones
• alarm on zone 1 and standby on zone 2
• alarm on zone 2 and standby on zone 1
• alarm on both zones
• tamper (wire cutting)
For each of these the SmartLinkAdv reads different
values of the equivalent resistance on the terminal,
shown below in Ohm:

Double zones with EOL resistors can discriminate 6
conditions on the terminal:
• standby on both zones
• alarm on zone 1 and standby on zone 2
• alarm on zone 2 and standby on zone 1
• alarm on both zones
• tamper (wire cutting)
• tamper (short-circuit)
For each of these the SmartLinkAdv reads different
values of the equivalent resistance on the terminal,
shown below in Ohm:
