Product Summary
The NXG-433 allows the addition of wireless devices to an
xGen system. These include wireless reed switches, wireless
motion sensors, universal inputs, and keyfobs. The xGen
control panel model you are using will determine the number of
wireless zones and keyfobs that can be added.
The receiver is in a self-contained plastic housing and
connects to an xGen control panel via the standard 4 wire
buss.
Additional features include: 2 zone inputs, 1 relay output, front
and rear tamper.
Current Limit Warning
Check the current requirements of your load before
connecting!
There is no overcurrent protection on the relay when providing
buss ground or bus voltage (jumper between - and C, or C
and +). You must ensure your load does not exceed the
recommended limits. Exceeding limits can damage the module
and pose an electrical hazard.
xGen panels do have PTC overcurrent protection on the bus
and may disconnect the buss to provide temporary protection.
If enabled, your panel will report "Overcurrent Fault" or
"Expander Overcurrent".
Installation Guidelines
When installing the receiver:
•
Leave 10cm clear around all sides of the module for better
signal reception
•
Avoid installing on or near metal surfaces such as filing
cabinets and metal roller shutters
•
Avoid installing on or near electrical devices such as
fridges, vacuum cleaners, air conditioners, computers,
washing machines, and motors
•
Avoid areas that are damp and wet such as inside
bathrooms and cool rooms
Installing the Receiver
1. Remove the front plastic housing by loosening the bottom
screw.
2. Carefully remove the circuit board from the rear plastic
housing by squeezing on the side tabs. Take care to put
aside the two rubber tamper switches.
3. Feed the buss cable through one of the cable holes.
4. Screw the rear plastic housing to a fixed surface. Higher
positions generally provide better signal reception.
