Addressing and Zone Numbering
Page 28
Detectors attached to an expander
Detectors attached to an expander take the address An<dd<ii (e.g. W1<04<00), where:
One or more letters showing the device type: W=Wired Expander, R=Radio
Expander.
Bus device number (see page 25).
Input number. This can be any number from:
00 to 09 for wired expanders or the EXP-R10.
00 to 29 for the EXP-R30.
Zone numbering for detectors connected to an expander
Each expander takes a sequential block of zone numbers up to the capacity of the device,
running on from any zones in the control unit or previous expander. The zone numbers are
dd0 to dd9 (for FSL or 2-wire CC wiring) or dd1 to dd5 (for 4-wire CC wiring), where “dd” is
the two-digit device number. Table 6 provides an example (refer also to Figure 8).
Note: Zone numbering for detectors connected to keypads is different; see the next
section.
Table 6: Example of expander zone numbering (i-on 40H)
1st Expander (e.g. EXP-W10)
Device number 04
Address W1-04
2nd Expander (EXP-W10)
Device number 05
Address W1-05
3rd Expander (EXP-R10)
Device number 06
Address R1-06
Zone numbering for zones on keypads
Several keypads provide terminals for up to two zones using FSL or 2-wire CC wiring, or
one zone using 4-wire CC wiring. To use the zones on the keypad, you must first enable
them from the Detectors/Devices – Wired (or Radio) Keypads Edit menu. For wired
keypads, you can use the same menu to select the zone wiring type of the keypad zones,
independently of the zone wiring type used by the control unit or the wired expanders. The
zone wiring type will affect the zone numbering.
When you enable the zones, the control unit assigns them to zone numbers starting from
the top of the control unit’s zone number range, as follows:
FSL or 2-Wire CC – Using the i-on30R as an example, the highest possible zone
number is 059. When the control unit gives an address to the first keypad to be
added, it allocates the zone number 059 to terminals Z2 on the keypad, and zone
