After power cut all lights on key pad have gone off. Power to base unit ok as the red light is on and light on outside box is on. Checked all fuses they checked out ok. Tried full power down no result. Did not get tamper alarm when power was switched back on with box front removed. Tried new battery still no power getting to key pad(power light not lit).
Installed in 1997 worked fine untill power cut Feb 2009. Hope some one can help.
Thanks Dave.

Hi Dave,

I am having a similar problem after a power cut. I Isolated power on mine and took the cover off and the engineers (don't you just luv them) had left all the install / service guides inside. Tried an NVRAM reset (to no avail) and have just attempted a fresh install as per the manual (also to no avail). Turns out a guy at work is an ex alarm guy and between us we believe that an 8 - 9 hours power cut will have drained an 8 year old battery dead. He told me that they used to replace them every 5 years and that recommended maximum is 7 years. If you are still looking for answers, I can scan and email you the manuals that I have and one I found online. Also, I have just found suppliers of new batteries (appx £10) and control units (£37).

Rgds,
