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.
Table 3: Line resistance
Zone type
Line resistance
Standard and active end-of-line EN 54-13 and intrinsically-safe
Mixed 40 Ω max. Not supported [1]
Automatic 55 Ω max. 50 Ω max.
Manual 55 Ω max. 50 Ω max.
[ 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 71 . To change the zone detection
setting, see “ Advanced configuration” on page 36 .
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.
Table 4: Zone terminations
Installation type
Zone termination
Standard and intrinsically-
safe zones
4.7 kΩ end -of-line resistor
EN 54- 13 zones EOL-Z end-of-line device (polarity sensitive)
Active EOL Active end-of-line device
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.
Connecting detectors
Connect detectors as shown in Figure 4 , Figure 5 , Figure 6, and Figure 7 starting
on page 11.
