Alarm 9800

[bellcrank]

We inherited an alarm system (9800 is only identifier) when we moved here 12 years ago, and till recently it's functioned perfectly although we have never had it serviced. Now, we are getting bF fault code and internal buzzer every now and then on the contol panel located in our hallway which can be cleared by inputting the user code twice, so it seems that a new back up battery is required I guess. I suspect that the battery is located in a plastic box in our roof space next to a fused spur.

Can anyone give me a precises step-by-step guide to doing this? Can I remove the battery to find out what I need to buy, or should I buy one in advance, if so which one should I get? Any advice much appreciated

If it is a 9800 then you will require a 12 volt 7.0 ah battery.
Get a new battery
Remove control panel lid
Silence with user code
Disconnect old battery
Re connect new battery red lead to positive and black lead to negative
Replace control panel lid
Reset system with user code
Caution 240v mains inside control panel.
Just replacing battery should be ok

Thanks for your prompt response, is there anything I can to to silence the buzzer until tomorrow?

No
You need a battery
You could disconnect internal sounder ?
Keypad will still sound
Is screwfix close to you ! Before they shut

Yes, made it to Screwfix, got a battery and just fitted it. It seems to have done the trick, no sounding just lT code flashing. Reset it and it's back to normal. Old battery has September '99 written in the side!! Thanks a million Handymanjo

Lt is lid tamper on the control panel
So when you reset that will go if you fitted lid correctly
Have you put a date on the new battery you fitted?

 

[bellcrank]

No, but I wrote it on the log sheet in the control sheet. Didn't give us any trouble last night

Batteries these days do not last as long as then 10-15years ago
Replace every 5 years
Glad you go a good nights sleep
9800 was a very good control panel in its day
Only problem could happen is with keypad
Suggest change code if you have change code for many years as buttons can play up
Well done !
