alarm system backup battery Questions

First of all the fire alarm should be connected to the main power supply of the alarm, and usually have a small 9 volt battery that you can buy anywhere as it's back up battery in case of power failure. This 9 volt battery should be changed every 12 months regardless as a safety precaution. It may even get it's backup battery power from the alarm systems backup battery, depending on the system itself. Have this checked out by a professional Alarm technician, it could save your life one day, keep it in tip top condition!!!!

Secondly the Alarm back up battery should be changed every three years to keep your alarm in tip top shape for voltage condition and in case of power failure. Any good electronics shop will have one the same as yours in voltage, amps and size. To take it out simply make sure alarm system is off, turn off main power supply to alarm system, open alarm box, and disconnect battery. If alarm goes off while disconnecting battery, don't worry, just continue. It will stop as soon as the battery is disconnected as long as the main supply is off. Installation is a reversal of these instructions, just remember that when you plug in the new battery the alarm might go off, simply continue installing the battery, close the box and it should stop going off. If it doesn't, simply enter the alarm code and that should turn it off. After all is well, remember to turn on the main power supply to the alarm. The battery should be fully charged within 12- 24 hours. If you see a strange symbol on your alarm panel, it is probably telling you that the battery is low on charge. this will go away after battery is fully charged.

Now last but not least, your false alarms are almost certainly from cheap and nasty, or faulty Detectors. Call out an alarm technician and get some decent Detectors installed that are not prone to false alarm. I have found Dual Technology to be the best, (they operate using microwave and passive infrared technology together inside each detector, and both must detect something at exactly the same time before setting off an alarm) these type of detectors are pretty much false alarm free. Make sure he gives you a well known brand like Honeywell or anything equivalent, and that he positions them for maximum detection, and thoroughly tests them before you pay him. The ever 20 hours I'm sure is nothing but coincidence. Your alarm could go off at any time in my opinion.

All the best
