How to Install and Program the GE Security NetworX NX-216Z8 Zone Expander
The GE Security NetworX NX-216Z8 is a zone expander module that allows you to add up to eight hardwired zones to your NetworX security system. The module can be installed inside the main control panel or in a remote location. The module communicates with the control panel via the data bus and can be programmed using a keypad or a computer software.
In this article, we will show you how to install and program the GE Security NetworX NX-216Z8 zone expander module step by step.
Before installing the module, you need to decide the starting zone number of this expander. The starting zone number must be on a boundary of eight zones, such as 9, 17, 25, etc. The eight zones then move out from this starting position. For example, if you choose 9 as the starting zone number, the zones on this expander will be 9 to 16.
There are stick-on zone labels to indicate the zone numbers that you select. You can apply them to the module cover after installation.
To install the module, follow these steps:
Disconnect power from the control panel and any other devices on the data bus.
Remove the cover of the module by pressing in on the two tabs at the bottom of the cover.
Select a location for mounting the module. It can be inside the control panel cabinet or in a remote location up to 1000 feet away from the control panel. If you mount it remotely, you need to use a separate UL listed enclosure and power supply.
Mount the module using screws or double-sided tape. Make sure there is enough space for wiring and servicing.
Connect the power wires to terminals 1 (+12V) and 2 (GND) on the module. If you use a separate power supply, make sure it has battery backup and is fused at 500 mA.
Connect the data bus wires to terminals 3 (DATA IN) and 4 (DATA OUT) on the module. The data bus wires are yellow (DATA IN) and green (DATA OUT) on the control panel. You can use either terminal 3 or 4 as DATA IN or DATA OUT depending on how you wire the data bus. The data bus must be wired in a daisy-chain configuration, meaning that each device is connected to only two other devices: one before and one after. Do not create loops or branches on the data bus.
Connect the zone wires to terminals 5 to 12 on the module. Each terminal corresponds to one zone number. For example, terminal 5 is zone 9 if you choose 9 as the starting zone number. Use 22 AWG or larger wire for zone wiring. The maximum wire length for each zone is 3000 feet. You can use end-of-line resistors (EOLR) or double end-of-line resistors (DEOLR) depending on your system configuration. Refer to your control panel manual for more details on zone wiring and configuration.
Replace the cover of the module and secure it with screws.
Restore power to the control panel and any other devices on the data bus.
After installing the module, you need to enroll it into the control panel and program its settings. You can do this using a keypad or a computer software. In this article, we will focus on keypad programming.
To program the module using a keypad, follow these steps:
Enter program mode by pressing *8 followed by your installer code (default is 9713). The keypad will display P - - -.
Select the module to program by pressing *56. The keypad will display M - - -.
Enter *99 followed by *1. The keypad will display M - - -.
