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 5 below.
Table 5: Zone terminations
Installation type Zone termination
Standard and intrinsically-
safe zones 4.7 k Ω end-of-line resistor
EN 54-13 zones EOL-Z end-of-line device (polarity sensitive)
BS 5839-1 zones Active end-of-line device [1]
[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 k Ω , 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 10.
The panel supports conventional detectors. To guarantee optimal operation, use
the detectors specified in the compatibility list. For more information on fire
detectors, see Chapter 5 “Technical specifications” on page 67.
Connecting manual call points
Connect manual call points in parallel, as shown in Figure 4, Figure 5, Figure 6,
and Figure 7 starting on page 10. Each zone circuit can support up to 32 manual
call points.
Manual call points must have a resistance installed in series with the normally
open (NO) contact to avoid short-circuit faults and to allow the control panel to
identify the origin of the alarm (automatic or manual). Note that many of the
MCPs in the compatibility list already include this resistor.
The resistance required will depend on the zone type as shown in Table 6 below.
Table 6: MCP resistances
Zone type Manual call point resistance [1]
Standard / BS 5839-1 EN 54-13 Intrinsically safe
Mixed 100 Ω Not supported Not supported
Manual 100 to 680 Ω 100 to 470 Ω 250 to 560 Ω
[1] Resistance must be rated at 1 W minimum.
