The System Bus i-on RangePage 30Numbering Zones on KeypadsThe key-kpz01 keypad provides terminals for up to two zones using FSL or 2-wire CCwiring. or one zone using 4-wire CC wiring. To use the zones on the keypad you must firstenable them from the Detectors/Devices – Wired Keypads Edit menu (see page 59). Usethe same menu to select the zone wiring type of the keypad zones, independently of thezone wiring type used by the control unit or the wired expanders. The zone wiring type willaffect the zone numbering.When you enable the zones connected to a KEY-KPZ01 the control unit assigns them tozone numbers at the top of the control unit’s zone number range.FSL or 2-Wire CC For i-onEX RangeUsing the i-on160EX as an example, the highest possible zone number would be 159.When the control unit gives an address to the first KEY-KPZ01 to be added then itallocates the zone number 159 to terminals Z2 on the keypad, and zone number 158 toterminals Z1. When you add the next KEY-KPZ01 then the control unit allocates the zonenumbers 156 to terminals Z1 and 157 to terminals Z2 on the new keypad. Note that thezone numbers do not have any relation to the keypad bus numbers.FSL or 2-Wire CC For i-on16 and i-on40The keypad zone numbering on the i-on16 and i-on40 is slightly different from the i-onEXrange. On these control units the zone numbers are linked directly to the keypad numbers.Keypad 1 always takes the two highest zones numbers, keypad 2 the next two highest andso on. Using the i-on40 as an example, keypad 1 zones take zone numbers 40 and 39,while keypad 3 zones will take zone numbers 36 and 35.The table below shows typical keypad zone numbers for each type of i-on control unitwhen using FSL or 2-wire CC zone wiring on the keypad.Keypad – FSL or 2-wire CC zonesControl Unit key-kpz01 aZ2, Z1key-kpz01 bZ2, Z1key-kpz01 cZ2, Z1and so on....i-on160EX 159, 158 157, 156 155, 154i-on50EX 49, 48 47, 46 45, 44i-on30EX 29, 28 27, 26 25, 24i-on40 40, 39 38, 37 36, 35i-on16 16, 15 14, 13 n/aZone Numbers for 4-Wire CCWhen you wish a keypad to use 4-wire CC zone wiring then the control unit still assignszone numbers at the top of the zone numbering range, but this time it uses only alternatezone numbers.
