Has anyone has any experience with the Melcom ST5500 (4 sector alarm kit). Just wondering if this panel will keep the SLA backup battery charged? Putting a voltmeter across the battery connectors gives no voltage (battery not connected).

I know this is an old post but it received no replies and I have the same question. It seems a bit stuppid to have to remove the battery periodically and find a way to recharge it.

Your panel should charge the standby battery.

Check there is 13.65v DC approx.at the end of the battery leads ( battery disconnected ) if not check the battery fuse.

Your battery should be replaced every 5 years approx.

If you have any doubts about electricity , leave alone and get a pro in.

Regards.

this Melcom 5500 is listed as a DIY kit, so where '4 sector' gets into it's description is anybody's guess and a bit strange, so i assume 4 zones used were meant.

i'm not sure but doubt if it has a 'safety' battery supply, like some Elmdene PSU's which will not connect the battery untill mains is applied.
