Security & Fire Protection Systems/NX-148 LC Keypad


We have purchased a building with an alarm system NX-148 (GE).   Power lines have been clipped.  We would like to rehook it up and have it set off a audible alarm and reset keycodes but the manual I found doesn't give any information on how to do that.  The company that used to be here is now out of business.  They were a security provider and administered their own system.  Attempts to reach them have not been fruitful.  Is there a more complete manual that could help us?  The user manual simply refers you to the installer for help.

Hello Susie, and thanks for your question.

The keypad you referenced is part of a Caddx system, and can be used with more than one model of control panel. So the key here is to find the main control panel (separate from the keypad), open it, and take note of the model number.

Once you have the model number, you can search online for the installation manual, which will contain the information you need.

In short, the manual for the control panel contains all the installation and operation instructions, including those for the keypad.

Does that help?

Best Regards,
