GENERAL INFORMATION 
 
The NX-8E NetworX from Caddx represents a new approach to the design of security 
systems. The NX-8E is probably the most flexible, durable, and user-friendly control panel 
ever seen in our industry. Its features include sophisticated software enabling as many as 
240 users to interface up to 192 zones, 8 partitions, with access, audio verification, and 
input/output modules, all reported with SIA and Contact ID formats which are extremely 
fast and...

FEATURE DEFINITIONS 
 
Abort  
If this option is enabled, the NX-8E will wait the programmed number of seconds (0-255) 
in location 40 prior to sending an alarm. During this delay time, the “Cancel” LED will 
flash.  To abort the report, type in a code and press the [Cancel] key. The LED will go out. 
If the report is not aborted within the allotted time, the LED will go out when the report is 
sent. The dialler delay is programmed at location 40, segment 8. Each zone can be...

Auxiliary power overcurrent 
The NX-8E will light up the “Service” LED on the keypad whenever too much current is 
being drawn from any device powered by the system. This condition can be reported to 
the central station (see location 37 segment 3). 
Box tamper 
The NX-8E has an input for a normally closed tamper switch (see wiring diagram). The 
box tamper can be programmed to report, and/or sound the siren and/or the keypad. 
These terminals can be enabled or disabled by...

Cross zoning 
This feature requires two or more trips within a specified time on one or more zones that 
are programmed as “cross zones” before it will report an alarm. During the time between 
trips, the NX-8E can be programmed to sound the keypad and/or the siren. The NX-8E 
can also be programmed to report an alarm after two or more trips on the same zone. 
The first trip on a cross-zone is also logged (see locations 37 segment 1, 39, 40 and 
110-169).

Expander trouble 
The NX-8E will report expander trouble to the central station if this option is enabled. This 
condition will light up the “Service” LED on the keypad, even if it is not reported.  
NOTE: The keypads are considered to be expanders. The number of expansion devices 
that are reported can be found in appendix 3 (see location 37 segment 3). 
Early to Open/ Late to Close 
If an opening occurs before the opening and closing times, the NX-8E will send an “Early...

Immediate restore by zone 
The NX-8E can be programmed to send alarm and restore reports as soon as they occur, 
or to wait until the siren time has expired or the system has been disarmed. (see location 
37 segment 2). 
Internal event log 
Up to 512 events can be stored in memory together with the date and time of the event. 
These events can be viewed later on via the LCD keypad, or by downloading. All 
reportable events are reported to the log. 
Keypad activated panics...

Manual test 
The NX-8E can be programmed to perform a bell and/or communicator test; to do this, 
enter [*]-[4]-[4] while the system is in the disarmed state. Each time that [*]-[4]-[4] is 
entered, a dynamic battery test will also be performed (see location 37 segment 2). 
Night Mode 
Applies to NX-1208E / NX-1248E keypads. In this mode, the control panel will bypass all 
zones that have the Entry Guard feature enabled. (See location 23 and 111-169)
