james.wilson Posted October 30, 2008 Share Posted October 30, 2008 total day mode current in A * 24 hours so if day mode is .5A then >5 x 25 = 12A/h Id also add 10% to allow for age of the battery @ 5 yrs securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Adi Posted October 30, 2008 Share Posted October 30, 2008 did you say day mode because you cant spell the Q word? day mode amps x 24 add full alarm load x 1.25 = battery size I really can't be ar**** with it anymore.

Chorlton Posted October 31, 2008 Share Posted October 31, 2008 thought it was 72hr min for AFD's? Link to comment https://www.thesecurityinstaller.co.uk/community/topic/25340-standby-calculation/#findComment-215204 Share on other sites More sharing options...
Adi Posted October 31, 2008 Share Posted October 31, 2008 OP asked for 24hr standby. Part 1 standard standby is 24hr, that time increases with regard to building being empty, say the weekend. Part 6 is 72hrs, thats why i the point that smokes on intruder should have 72hr standby but no one wants to discuss this point. I really can't be ar**** with it anymore.

L1-L4 usually 24hours will suffice, P1-P2 will require 72 hours. Both + 0.5 hours alarm time.
