Caddx NX-4 Control Panel

The NX-4 is the smallest Caddx NetworX panel, later sold under the GE and Interlogix names. It was built for apartments and small homes: four zones on the board and up to eight in total. It uses the same keypads, sensors and programming as the larger NetworX panels, so everything you learn on it carries over.

At a glance

Limits to know

• Only one module. The installation manual allows up to 8 keypads and one other module (not counting hardwire), so a wireless receiver and a communicator cannot both be added as separate modules. An NX-148E-RF keypad, which has its own receiver and enrolls as a keypad, is the usual way around this.
• No zone doubling. The NX-595E manual notes that zone doubling is not available on NX-4 panels.
• Eight zones maximum. If you need more, the NX-6V2 and NX-8V2 take the same keypads and sensors.

Official manuals

Interlogix's document library is no longer online. These links open archived copies of the original manufacturer PDFs on the Internet Archive.

• NX-4 installation manual (Rev N)
• NX-4V2 user manual (Rev C)
• NetworX control panels data sheet (NX-4, NX-6, NX-8, NX-8E)
• NX-4 user quick reference (Spanish)

When the Service light is on, press * 2. The zone light that comes on gives the type of trouble: 1 system, 2 tamper, 3 wireless low battery, 4 wireless supervision, 5 zone trouble, 6 phone line, 7 communication failure, 8 clock lost. See the NetworX service light guide.

Beeping after a power cut

Enter your code to silence it. Then set the clock: press * 9 7, the master code, and the time as four digits in 24-hour format.

Siren does not sound

The siren output drives a speaker by default. For a self-contained siren, the installer must switch the output to voltage in programming.

Old phone-line monitoring

If the landline is gone, the panel reports phone and communication troubles. Because the NX-4 takes only one extra module, a cellular communicator uses up its expansion. Plan wireless through an NX-148E-RF keypad if you need both.

• Keypads: NX-108E, NX-148E, NX-148E-RF.
• Wireless: NX-548E receiver, or an NX-148E-RF keypad.
• Communication: NX-592E GSM, NX-595E IP.

• Default codes: master (user 1) 1234; go to program code 9713.
• Program mode: with the system disarmed, press * 8. The five function lights flash. Enter the go to program code; the Service light flashes when you are in.
• Location 42 holds the go to program code. A six-digit code option exists; if you enable it, make sure the go to program code is six digits first.
