I have an intruder/fire alarm system that I can not indentify. The keypad has the name CALIFORNIA SECURITY PRODUCTS LTD. on the top left hand corner above the lcd display. Most of the circuit boards for the smoke detector units and controllers have the words SENSOR TECHNOLOGIES UK LTD. printed on them as does the main panel which also has a radio receiver circuit attached to it. The circuit diagram has no indentifying labels. Does anyone have a clue as to who manufactured this system? Thanks in advance.

Just a guess, but sounds like a "Electronics Line" panel, the kel880

Not a good pic, but dose it look like this:

Many thanks guys! (I did post a thank you earlier but it doesn't appear here!!)

The picture of the controller is bang on! I shall investigate the links and let you know how I get on. I must change my search engine! I spent hours on the net trying to trace the system.

I am now off to try and get some manuals and have a play!
