dazoman1 Posted April 27, 2014 Share Posted April 27, 2014 just power up by battery then apply AC will be fine Link to comment Share on other sites More sharing options...
zerozero Posted April 27, 2014 Author Share Posted April 27, 2014 Unless you bought it from cheapjacks.com all SLA batteries retailed should have a 100% charge. Aha that is important. Thanks I will check with multimeter but this is good to know. I dont know the panel but battery first in the old days of fuses was to ensure it popped a fuse not a component Thanks James, but sorry if I'm being thick - I still don't understand this. This panel has fuses for both the PSU and the battery, so why would the risk to components be different depending on power source? Was this not the case "in the old days" or is there something else going on that I am not understanding? Thanks to everyone for the suggestions and advice.

james.wilson Posted April 27, 2014 Share Posted April 27, 2014 a lot of panels dont have the power to blow a fuse without a battery. ie a 1.6a fuse can take nearly 3a to blow securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Rulland Posted April 27, 2014 Share Posted April 27, 2014 As above, if there's a problem /fault it's going to show up pretty darned quick . Any 'shorts' etc will become apparent wether just on battery or mains, It's a 'short '...... Link to comment Share on other sites More sharing options...
james.wilson Posted April 27, 2014 Share Posted April 27, 2014 High rest shorts can overload the input stage. If inexperienced power up on battery imo then add mains securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

zerozero Posted April 28, 2014 Author Share Posted April 28, 2014 So I turned it on. Lots of messages including Battery Fail (which I wasn't expecting as the batt is connected) and AC Mains off.. Connected the mains and it blew the fuse before the PSU.. what could cause this? I replaced the white fuse with a clear one that was in the accessories pack that came with it but this blew also and I'm not sure what to do next as I don't think I have a spare 3.15 A slow blow fuse lying around/ If I disconnect the battery now will the main alarm go off? If so how do I turn the system off to troubleshoot without causing the main bell to go off (test strobe 3 times?) and what should I look for when troubleshooting? Thanks for any help!

matthew.brough Posted April 28, 2014 Share Posted April 28, 2014 Use a nail instead of a fuse. That'll do it . . . www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
9651 Posted April 28, 2014 Share Posted April 28, 2014 lol Yesterday I was going to say, check for any wiring shorts first........................ I never power any panels up with any aux power connected. Only powered items are network devices, keypads/rios etc. Then add powers from there. Probably a legacy from scantronic days Link to comment Share on other sites More sharing options...
Cubit Posted April 28, 2014 Share Posted April 28, 2014 Use a nail instead of a fuse. That'll do it . . . Possibly the cause in the first place. Link to comment Share on other sites More sharing options...
