Don't forget you need headroom to recharge the battery after a mains fail and consider standby time. 

What do you mean exactly? The battery is the correct size for the panel (7ah), my system is not that loaded its 240ma in standby and 840ma in alarm.

Cheers 

Oh ok 240 is fine I wouldn't personally go above 75 percent on alarm so I'd either put a psu in or scb more sounders

Thanks, worst case i will scb both external sounders, do you think it would work in reality? The elm300 i intend add will draw 80ma max but i imagine once its onboard batteries are fully charged it will be even less than that. Did you ever use these panels? If so can you remember what the hold off circuit is rated at?

SCB both , no one listens to them outside much 

 

Your better off making sure internal Sounders are adequate and signalling 

You do have a point tbh, i rarely see anyone take any notice of a bell box sounding, the internal sounder i have at the moment is the elmdene speaker which is Loud but not quite loud enough to drive you out house hence why i bought the elm300 give the sound a boost indoors.

Just one more thing regarding the panel power supply, does each 12v output such as the bell circuit have its own individual polyswitch?, if so what are they rated at? Or are all the 12v outputs commoned together and protected by one big polyfuse rated at 1250ma at 20 degrees and at worst case 800ma at 40 degrees?

No I've never used scanny

Yes   im well familiar with the 9600   strange panel as the 9800 came out later with 2 7 segment led displays like the 9100 ,which is scantronics first panel 

Launched because the market demanded a lower cost

There's a surprise
