Richard Posted May 26, 2013 Share Posted May 26, 2013 Hi, I have a problem with an Accenta LCD RKP. Whilst on holiday the power tripped and eventually the alarm battery drained. On resetting the power I have the alarm system back up and running however the LCD display on both remote keypads is showing black squares. The keypad itself and alarm system appear to work fine but obviously with no functioning display. This setup is simply a mini G4 with 2 LCD Keypads. Hopefully there is a simple fix but I’ve not come across this before. Any advise would be greatly appreciated. Richard Quote Link to comment Share on other sites More sharing options...
james.wilson Posted May 26, 2013 Share Posted May 26, 2013 Did you power it back up with the flat battery connected. A completely drained battery will be damaged. If its now took charge have you powered it down and back up cleanly Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

arfur mo Posted May 26, 2013 Share Posted May 26, 2013 as above these panels do like mains on before battery, this means you have little option than to have the panel lid open. please beware of the internal mains fuss block and your straying little pinky. for best safety, disconnect battery remove then restore power from the mains spur fuse unit (or plug) feeding AC power to the controls (that should be near it and marked).

Richard Posted May 27, 2013 Author Share Posted May 27, 2013 Thanks guys. Yeah the the power was simply reset, assuming everything would come back up and battery would recharge. When I get back there I'll fully disconnect and power up on mains only first. Thanks again. Quote Link to comment Share on other sites More sharing options...
Alarm Protection Posted May 27, 2013 Share Posted May 27, 2013 I would buy a new battery first! Quote ! Link to comment Share on other sites More sharing options...
Chris_A Posted August 9, 2022 Share Posted August 9, 2022 Sorry to revive a very old thread, but if the battery is flat is there no way of reviving it? Only option is to buy a new one? Quote Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted August 9, 2022 Share Posted August 9, 2022 SLA batteries are rechargeable but they have a lifecycle, deep discharges can damage them internally. The control panel if working correctly will keep the battery charged at an ideal rate. Generally a well maintained system will have it's charging rate and voltage checked annually and batteries replaced at 4-5 year intervals.

Only option is to buy a new one? Its sealed unlike a car battery so there is no fix for it. Replace it is one option, but if you dont like your neighbours you could not bother with a battery at all, then in every powercut the external sounder will sound and upset them. Or if you like to gamble you could just leave the battery in the panel may catch fire, it may not. To be fair never heard of one catching fire in a house (an engineers van caught fire recently due to old batteries) but there is always a first time. If you dont like the sound of those options you should either, replace the battery, get the alarm serviced, or decommission the system completely Quote Link to comment Share on other sites More sharing options...
