Connecting Zones And Zone Devices - Ziton ZP1-F2 Installation Manual

Connecting zones and zone devices

Connecting zones
Connect zone wires as shown in Figure 4, Figure 5, Figure 6, and Figure 7
above. Line resistance is shown in Table 3 below.

Zone type
Mixed
Automatic
Manual
[1] Mixed zones are not permitted in installations requiring EN 54-13 or intrinsically-safe
configuration.
To measure the line resistance:
1. Create a short circuit at the end of the zone line.
2. Measure the resistance between the positive and negative lines with a
multimeter.
Note: The default zone detection settings for each operating mode can be found
in Appendix A "Configuration presets" on page 89. To change the zone detection
setting, see "Advanced configuration" on page 43.
Terminating zones
Zone termination is required at all times, whether the zone is used or not. The
type of termination depends on the installation, as shown in Table 4 below.

EN 54-13 zones
BS 5839-1 zones
[1] For BS 5839-1 installations an active end-of-line device must be installed (instead of an end-
of-line resistor).
Note: Unused zones must be terminated with an active end-of-line device or
configured as passive end-of-line and terminated with a 4.7 kΩ, 5%, 1/4 W end-
of-line resistor.
