Micro controller switch
The Terxon 2WAY wireless module is based on a PIC micro controller by Microchip.
HF transceiver and antenna
The Terxon 2WAY wireless module has an 868.6625 MHz narrow-band transceiver and a PCB antenna
with diversity function.
Internal Piezo signaller (8)
A small Piezo signaller is installed. It outputs an acoustic signal indicating whether a component has been
trained successfully and signalises statuses in setup mode.
Power supply
The power supply is connected to the 2 left connections labelled "+12 V / 0 V IN" on the upper terminal
block. Please ensure that the polarity is correct. The Terxon 2WAY wireless module is protected against
incorrect connection and therefore destruction by a pole protection diode. To ensure emergency power
operation, we recommend using the alarm centre for the Terxon 2WAY wireless module power supply.
Please take into account the maximum load of the external power connection of your alarm centre! The
Terxon 2WAY wireless module requires a maximum of 300 mA. If additional components are connected,
the total required power must not exceed the maximum load.
If you are not using the alarm centre's power supply but a separate PSU for the Terxon
2WAY wireless module, please take the following into account:
- Connect the earth connection of the Terxon 2WAY wireless module (0 V IN) to
the earth connection (0 V) of the alarm centre. This ensures that all voltages in
the system refer to a joint earth
potential.
- If the input voltage is missing on
the Terxon 2WAY wireless
module, all outputs are open. This
can cause undefined statuses in
your alarm system. Hence, make
sure that emergency power supply
is available.
