Need some help.

I am decorating and needed to extend the cable to a detector. Foolishly I did not think of taking the fuse out the spur and cut and joined the cables. No power on the keypad!

Replaced the fuse and power is back to keypad and detectors but the keypad just shows ***************** and does not respond to anything (other then beeping to acknowledge a key being pressed)

Any ideas?

The data line is missing.

Go back and connect colour for colour.

The keypad was probably on the same cable as the PIR.

agreed, you are missing data. You have either fried the data line (unlikly but depends on what you shorted to what and for how long), or you havnt joined the cables correctly

Thanks guys - sounds promising I will recheck the connections I made - However the PIR I extended is seemingly workingin the sense it detects me etc...

I will check connections once more.

Well I have remade all connections and reconnected fuses - same problem. The keypad powers up and makes a continous bleep till a key is pressed and shows **************** the little led at the bottom left of the unit flashes on and off green very second.

Does this indicate fried data cable? If so are we talking the feed of data back from the PIR or the keypad to panel, if keypad to panel can I not run a fresh link between the two?

Could the keypad itself be damaged?

it wont be the cable thats fried

Yes sounds like the panel has been fried. Assuming the cable is wired ok

have you messed with the keypad address at all?

To good a panel to fry have a look at internal fuses better still (poss cheaper)get an Engineer in to have a look

Back to basics, flylead the keypad at the panel.

Also should be 13.5vdc at keypad +/- and 1 to 1.8 vdc on the data line.
