My daughter has just bought a flat in Bristol, and has inherited a wireless burglar alarm system with no instructions. The previous owner is not in a position to help, and the selling agent denied there was an alarm fitted.
The system comprises a few wireless PIR detectors, a wireless external sounder, an internal sounder, the main box of tricks, and a keypad. It appears to include an autodialer. The only maker id I have found so far is a logo on the keypad with what might be "I Electronics", but googling the likely possibilities hasn't helped.
Does anyone recognise any of the components, please?
