We inherited a Scantronic 9800 with our new house. This afternoon the keypad alarm went off repeatedly with the code bF flashing. We have now turned off the mains electric to the alarm, now the power light and the code Lb are flashing. We understand this means the battery needs replacing - can we do this ourselves? Is the alarm likely to go off again when the battery drains further or not? Basically we don't want the alarm going off every five minutes until we (or an engineer) replace the battery.

Many thanks in advance.

you can do this yourself, but be careful as mains voltages are present.

you may have a problem whereas the charging circuit may have blown due to the age of the battery, in which case an engineer is advised

Thanks CB for the prompt reply.

Now that the battery is low will the keypad alarm start going off again as the battery charge drops further? I can't replace the battery before tomorrow at least and I'm worried the keypad alarm might go off every five minutes throughout the night tonight.

thats possible but very rare (in my experience) with the 9800 as it's a pretty robust unit making it a 'goldern oldy', replace the battery 1st as thats the cheapest and quickest option, but call an engineer as the alternative especially as the system seems not to have been loked at for some time.

the system will keep signalling the battery fault, unfortunately we can not assist in showing you how to overcome this as the information could be directly used by a criminal.

i very much doubt it, unless you have power cut. but if the panel charging circuit is fried, maybe im afraid

If anyone can recommend a good engineer in/around Enfield (North London/Middlesex) I may have a bit of business for them.

Edit I found a local chap from the SSAIB website.

Thanks in any case
