Thevolume of alarm tones is fixed.SofterEngineering KeypadAn Engineering Keypad is a modified i-kp01 thatcan be plugged into a dedicated connector on thecontrol unit PCB (see 12 in Figure 3) or any of theexpanders (see 13 in Figure 15 or 10 in Figure17). An Engineering Keypad does not need to beaddressed, and will always be recognised by thecontrol unit as an Engineering Keypad.You can use an Engineering Keypad to programthe system without being tied to any of theinstalled keypads. If you wish to move anEngineering keypad from one connection point toanother then you can do so without removingpower from the system.Step 4. Fit and ConnectExpandersBoth wired and radio expanders are supplied inthe same plastic case. Use M4 25mmcountersunk screws in all three fixing holes whenmounting the back of the case on the wall. Ensurethe screw has a thread suitable for the wallmaterial. See Figures 15 or 17 for the position offixing holes and cable entries.Note that radio expanders are not approved forSecurity Grade 3 systems.Connecting an Expander to the BusBoth wired and radio expanders provide aconnector for the bus at the bottom of their pcbs(item 13 in Figure 15 and 11 in Figure 17) .Figure 30 Wiring ExpandersAddressing ExpandersThe control unit assigns addresses to all devicesconnected to the bus cable. You can start thisprocess off from the Installer Menu, during theinitial power up. See “Initial Power Up” on page 25for instructions. Alternatively, you can add andaddress new expanders at a later date.Expander LoudspeakersDuring normal operation loudspeakers onexpanders repeat setting and entry tones for thepartition that the expander is allocated to. Duringan alarm the loudspeakers repeat alarm tones.Each loudspeaker draws up to 280mA inoperation. if there is more than one expanderloudspeaker then the bus may not be able tosupply sufficient current during an alarm.Note that initially the volume of the expanderloudspeakers is set to zero. You must set thevolume of entry exit tones from the expanderloudspeakers from within the Installer Menu,please see the i-on Range Engineering Guide.Step 5. Connect Control Unitto MainsWARNING: ENSURE THAT THE MAINSSUPPLY IS DISCONNECTED AND ISOLATEDBEFORE MAKING ANY MAINS CONNECTIONS.All mains electrical connections must be carriedout by a qualified electrician and must comply withthe current local regulations (e.g. IEE).Mains CablingNote: To avoid mains interference, the mainscable must enter the control unit through its owncable entry hole (10 in Fig 2) and must not bemixed with other cables.Mains ConnectionFigure 31 shows the mains connection. Connectto a suitable supply using a double poledisconnect (isolation) device in accordance withEN60950-1.Caution: Do not apply power at this point.Anchor the mains cable with a strain-relief tie.There is a eye located near the mains cable entryhole for this purpose.0V 0V+12V 12V AUXA B 0V +12V A BZ3 Z4Control Unit ExpanderTo next device
