BATTERY STANDBY

Intheeventofamainsfailure,two12V5Ahrechargeablebatterieswillmaintainatypical
systemforapprox.8hours.Aprotectioncircuitwilldisconnectthebatterysupplyinthe
eventofprolongedmainsfailuretopreventdamagetothebatteries.Themainssupply
mustbeappliedfirsttoenergisetheprotectioncircuit,i.e.thesystemwillnotfunction
bysimplyconnectingthebatteriesalone.

