Note: The default zone detection settings for each operating mode can be found
in Appendix A "Configuration presets" on page 79. To change the zone detection
setting, see "Advanced configuration" on page 39.

Connecting inputs

Input functionality
Each control panel has two inputs, marked INPUT1 and INPUT2. These circuits
are connected as normally open and activated when closed.
Both inputs are configurable (see "Input configuration" on page 47). The default
functionality of each input is defined by the panel operating mode and EN 54-13
configuration. See Table 7 below.

Connecting unsupervised inputs
Connect unsupervised input switches to INPUT1 and INPUT2, as shown in
Figure 4 or Figure 5 on page 11. Nominal resistance values (including any cable
resistance) are shown below.
