Thecontrolunitissuppliedwiththe(RED)posivecabletothebaerydisconnectedandisolatedbymeansoftape,toavoidthe
baerydischargingcompletelyandbeingdamagedbeforeinstallaon.
Thecontrolunitisedwithquickcouplingterminals,whichallowquick,opmumconnecon
oftheplant’swires.Theterminalsaresuitableforwireswitha0,5to1,5sq.mmsecon(20to
16AWG).
Seethe“ELECTRICALCONNECTIONS”wiringdiagramsinthismanual.
Thecontrolunitcomeswithsomeresistors/capacitorsedontheconnectors,toallowyoutoswitchitonwithoutanydevice
connected,andwithoutanalarmbeingacvatedonthecontrolunititself.
Whenconnecngtheaccessories(smokesensors,pushbuonpanel,actuators),theseresistors/capacitorsmustbemovedas
showninthe“ELECTRICALCONNECTIONS”diagram:
• the10kOhmresistorsontheSMOKEandEMERGENCYBUTTONterminalsmustbemovedasshownindiagram8onpage52.
