Installing and Maintaining i-on10Page 15Doors attribute set (see page 31). The zone must use 4k7 shunt resistors and a 2k2 EOLresistor.Figure 4. Two detectors per zone (Double Doors)4-wire CCThis uses a separate pair of wires for the alarm and tamper contacts. No end-of-lineresistors are used. Selecting 4-wire CC normally halves the maximum number of wiredzones that can connect to the i-on10. However, an ADP-10CC board can be fitted toconvert the ten FSL zones to ten 4-wire CC zones. Without the board fitted, the control unitsupports five 4-wire CC zones. If you are using an ADP-10CC board, select 2-wire FSL2k2/4k7 as the wiring type.2-wire CCThis uses a single pair of wires for each detector. No end-of-line resistors are used.Checking cable requirementsStandard cable typeNormally, the control unit requires standard 7/0.2 un-screened 4-core alarm cable forwiring to keypads and wired siren/strobe units.Screened cableFor maximum performance in environments where there is electromagnetic noise, usetwisted-pair screened cable with a characteristic impedance of 100-120 Ohms, such asBelden 8132 or cable designed for RS485.If screened cable is required:1. Avoid earth loops by connecting the screen on the cable to mains earth at thecontrol unit but not at the keypad.2. The continuity of the cable screen is most important and screens MUST becontinuous along the full length of the cable.3. Where the cable enters any metal enclosure, ensure the screen is isolated fromthe case.Cable segregationSegregate bus cabling to keypads from any other wiring, such as mains cables, telephonecables, computer network cables and R.F. cables.Keep cables to keypads clear of cables supplying extension loudspeakers or any high-current devices.Mains cable routingUse separate cable-entry holes in the enclosure for mains and signal cables. Please referto the i-on10 Installation Instructions for details of the holes to use for each type of cable.EOLTamperTamperAlarm Alarm
