When this wiring mode is used, ensure only one detector is set to report fault conditions, and
limit the number of detectors or contacts of any type to a maximum of 2.
Note: The recommended maximum cable run from a zone to a detector is 500 metres in all
other configurations.
In end-of-line mode use the wiring shown in Figure 5.

Wire keyswitches
Latching or spring loaded keyswitches can be used to set and unset the panel. To program
keyswitches, refer to Program Zones [52].
If the keyswitch latches, the transition from 1 kΩ to 2 kΩ initiates the setting procedure of
an unset system, the transition from 2 kΩ to 1 kΩ instantly unsets a set system. If the system
is already set, then the transition from 1 kΩ to 2 kΩ has no effect. If the system is unset, the
transition from 2 kΩ to 1 kΩ has no effect. This is programmed as a
Keyswitch in the
Program Zones [52] option.
