Power Calculator
A table that provides a guide to the overall power consumption of the Comfort system - it could take the no of keypads the items used in each zone etc etc and provide an indication of the overall power used and thus the estimated battery life following a power out.
Perhaps comfort could also measure the power being drawn?
DONT forget if you are using Comfort as a smoke alarm then the back up time needs to be extended over the back up time for a security alarm.

This Table can be found in Installation Manual Page 17 \"Backup Battery Calculations\"

Ugh
My original post forgot to mention the basis of the suggestion.... Should this power calculator not be added into Comfigurator, indeed extended if posible to monitor the power output of the unit (or indeed units KT03 or Keypads or slaves etc)!

That may be a good idea for future

OK - add to the wish list
I think it would also be a way of highlighting the fact that if there is a fire (smoke heat or CO) sensor attached that the battery back up capability should be extended.

Note that Slaves have their own power supply and battery unlike other systems where all the current comes froom the main panel
This allows you to spread the load among different slaves so you do not need to use large batteries which take much longer to charge
This make the Power caluclator fumction in Comfigurator not so simple as you need to know where the power comes from

So even more reason to provide some sort of power calculator then - even if it is only a guide line?

Hi,
Which installation manual is the battery backup calculator in?
I looked in the both \"quick install\" and \"supplementary installation manual\" and could not find any table?
Thanks,

That was from an old installation manual. I will see if it can be found

This was in the old Comfort 1 Installation manual
Back-Up Battery Calculation.
Standards require that alarm systems must be designed and installed
with adequate battery back-up capacity to run the system for a minimum number of hours upon a loss of mains power. To do this, first establish the system ââ¬ËQuiescentââ¬â¢ Current (QC). This value in Amps should be multiplied by the minimum time duration that is required under the relevant standards. The Amp/hour battery size should be of a higher capacity than the result of the calculation. It is always advisable
to install the highest capacity battery which can physically fit into the
enclosure (7A/hr).
E.g.: QC = 0.650 A (650 mA)
8 hours required stand by
QC x 8 = Battery Size A/hr (Min)
0.650 x 8 = 5.2 Amp-hour, Next available Battery size is 6
Amp-Hour
