Guest pb.brown Posted February 15, 2006 Share Posted February 15, 2006 Hi, every time we have a power cut my alarm goes off!!! We get an error message of Fb which I presume indicates that the battery needs replacing. Any chance of some pointers, ie can I as a user remove the cover without the need for engineer codes and if so where do I get a new battery from.

whistle Posted February 15, 2006 Share Posted February 15, 2006 Trust me for what its worth get an engineer out and he will service and replace the battery. Well worth it. Link to comment Share on other sites More sharing options...
arfur mo Posted March 8, 2006 Share Posted March 8, 2006 hi pete, its very rare on Gardtec systems for the charging circuit will be damaged, even a totally flat battery - never happened in my experience in some 20 years in both using Gardtec Panels or attending 'fitted by others' with totally shorted plates. even if the supply regulator was damaged and the board has to be replaced, the system would still need a new battery, so it is not a wasted expense for the owner.

Guest Alarm Guard Posted March 8, 2006 Share Posted March 8, 2006 With respect though he is wrong, shorted plates will blow a fuse so would not normally damage the charging circuit.Its basic electronics and basic common sense, a dead battery draws more current in most cases more than the charging circuit is designed to deliver. Over time (and lets face it we are talking about batteries that should of been replace years before) this inevitably will damage the charging circuit. If you dont believe me go out side start your car and rev it at 8000 revs for a year or so and see what happens, you will find that if the engine does survive it wont last as long as you would of expected it to if you hadnt done. I also have been in this industry for over twenty years, and I have seen quite a few panels that are unable to charge batteries due to overloading. And just out of interest (humour me) what difference do you think it makes if you check the voltage at a detector head or at the panel? Pete ....and of course Pete, someone who has not had the battery in his alarm panel replaced since the 20th century is not likely to own a meter that has been calibrated... B) .. so testing for voltage is probably going to be futile anyway... Paul Link to comment Share on other sites More sharing options...
