How to Increase Caddx Panel Voltage

Regular GE (Interlogix Networx) CaddxCaddx Panel voltage NX8E (Euro panel) Security Alarm system voltage is around 12V DC. This voltage feeds AUX+ and SMOKE+ components in addition to backup BATTERIESCaddx Panel voltage. For most regular configurations this voltage is enough. But as the number of connected components increased, stability of the caddx alarm systems begin to decrease and backup batteries can’t be charged fully. Consequently, you can see “Low battery” Alarm message in Caddx keypad (*2). Even if you change the battery with the new one, after a few weeks, you get the same Low Battery error message.

Increase Caddx NX8E Security Panel Voltage

Warning: This procedure is mainly for Caddx NX8E (Euro Panel, eg. E-panel) Security panels. Don’t use that procedure for regular Caddx NX8 Security panels. Otherwise your NX8 panel locale (213#) will be change and you must re-program your NX8 alarm panel! If you have Caddx NX8 panel, work at location 214# , not 213#.

In order to increase overall Networx Caddx NX8E panel voltage, enter the following commands at Caddx keypad

*8-YOUR_PASSCODE

0#

213#    // For NX8 panels, use location 214#

-> in Segment-1, enter 53*

->in Segment-2, enter 205*

->in Segment-3, enter 225*

As a result of this set of commands you should get around 14.5V DC voltage from AUX+ and SMOKE+ ports of GE (Interlogix Networx) Caddx security alarm panel. If you have a multimeterCaddx Panel voltage, you can measure panel voltage from SMOKE+ (or AUX+) ports and COM (-) ports.

Even if you increased panel voltage, you may see “Low Battery” messages, up to 2 days. After 2 days, that message disappear, if no other problem exist.

Warning! You must do that procedure if you have instability issues or having “battery low” errors, despite you have changed your security panel battery recently. Otherwise, don’t change your panel voltage.

  1. Dear Sir.
    I started using CADDX panels as far as I remember in 1991, I distributed their products for a long time till country economy got vary bad, I´m writing from Argentina. I was very satisfied with caddx products but unfortunatelly Joe Hurst and Stevens sold the brand to Sentrol first then GE, UTC …..
    When I worked directly with CADDX we used to get a very good feedback from them and contributed many times finding bugs that they corrected inmediatly, this kind of support dissapeared when they sold the company. Now with near 1000 panels installed we receive the advice that thhe panels will be no longer manufactured. My question is, if there are any european alternative for NX-8E line.
    Thanking you in advance

    1. Actually CADDX series was a legend. Extremely robust and easy to use. But, As You said, end of the road is seen. Currently, maintenance products are available, but almost no new features.
