9448 Alarm System Keypad Problem

[adclark1987]

Hi

I have a 9448 alarm system with a main unit upstairs in the cupboard and a separate keypad next to the door. I have just returned home from a weekend home and found the keypad by the door to not be working. I have not had a power cut as far as I am aware. The key pad is fully lit up and beeps when keys are pressed - the light for mains power supply is also lit but I cannot function the alarm (i.e. set it, turn it off, use the panic feature) at all with the key pad. Has anyone got any suggestions how I might fix this?

Thanks

A mouse has eaten the cable? If you have a multimeter or continuity tester, disconnect the keypad cable at both ends, strip and twist ALL the conductors (including any spares) together at one end and then check continuity at the other end. Check red to black, blue, yellow, green, white, brown, orange then black to blue, yellow, green, white, brown, orange, then blue to yellow, green etc., etc.. If you've got no continuity, you've got a broken cable. If some of the wires are okay, use them and chop off the broken ones.
