Alarm Problem (IntelliSense Securit 800L)

[Tipson]

I have an IntelliSense Securit 800L house alarm installed and following a recent power cut, the mains light on the keypad is not alight. When I press the keys, the pad beeps and the backlight comes on, but alarm does not set.
Could this be the fuse and or backup battery. The battery is quite old.
Thanks
PS All PRI’s are working.

If the backlight comes on I can't see it being a fuse. Does the alarm accept your code? If not it may have reverted to the factory code. (iirc it's 1234.) All old batteries should be changed as a matter of course. Does the keypad bleep when you press the buttons?

Thanks for info Joe-90.
The alarm does not accept my code and I have tried entering 1234 without success.
I will replace the battery anyway.
Yes the keypad does beep when \I press the buttons.
Any other suggestions would be appreciated.
