adrian41uk Posted April 14, 2013 Share Posted April 14, 2013 We all know that the gel batteries in an alarm panel should be replaced at regular intervals but what about the battery packs in SABs?I know that these are usually a different battery technology (usually NiCAD or NiMH) as opposed to the lead acid types used for panel backup and are usually soldered in but they must have a servicable life?Does anybody routinely replace the module/entire bell box after a certain number of years or are they just left to die?

Lwillis Posted April 14, 2013 Share Posted April 14, 2013 Same here. No routine replacement but tested on a site Maintence visit. How long would you guys say a bell should last/be replaced , I'd say around 10 years Link to comment https://www.thesecurityinstaller.co.uk/community/topic/34360-bell-boxes-sab-batteries/#findComment-313814 Share on other sites More sharing options...
matthew.brough Posted April 14, 2013 Share Posted April 14, 2013 In the real world I'd expect 99% of them to be left to die. www.securitywarehouse.co.uk/catalog/ Link to comment https://www.thesecurityinstaller.co.uk/community/topic/34360-bell-boxes-sab-batteries/#findComment-313815 Share on other sites More sharing options...
adrian41uk Posted April 14, 2013 Author Share Posted April 14, 2013 Thanks for the replies, Guys. Tested as in remove the hold-off voltage & let it sound for the full 15min? Or just quickly remove hold-off & let it sound for a few seconds? Or just Bell test from the panel (which doesn't actually use the SAB battery....)

matthew.brough Posted April 14, 2013 Share Posted April 14, 2013 The only way to test properly is drop the power and see if it rings for the full time. www.securitywarehouse.co.uk/catalog/ Link to comment https://www.thesecurityinstaller.co.uk/community/topic/34360-bell-boxes-sab-batteries/#findComment-313820 Share on other sites More sharing options...
