Hi I recently added 3 new sensors and 1 keypad to my existing alarm panel after having an extension. The sensors work fine but the keypad isn't. The buttons are lit up but nothing else seems to work. The existing keypad still works and I've connected it up the same as the original.
Any help much appreciated. Many thanks.

The tamper circuit is in series. See bottom of page 5 for example
with two keypads.

No, I don't know a thing about the topic :-)

And make sure it's the manual for your system...
