Zone status and resistance values
Installer mode -> Test -> Zone resistance
Here you can see the number, name, allocated partitions, zone type and the actual re-
sistance value of the zone.
The resistance value changes when you open and close the alarm contact/tamper contact
of the zone.
Resistance ranges specified for idle, alarm and tamper states (in Ohms).

Resistances immediately by the screw terminals.
The following parameters impact the actual resistance value of the detector circuit:
•
Line resistance of the cable
•
Resistance tolerances
•
Contact resistance at connections and switches
Recommended cable resistance: must be less than 100 ohms.
Note
The only difference between the wired zones on the alarm panel is:
500 ohms for 4-wire CC and 800 ohms for 2-wire CC in place of 1000 ohms.
You can find details on this in the installer manual chapter Technical data
– wired
zones in the appendix.
Installer mode > Test > Walk test
Here you can test the zone alarm and tampering.
