Installation Manual
Introduction
The uRx can be used as a data receiver and as a
Roboguard Decoder. It will learn ANY roboguard
signal ie tamper, intruder, remote and Autotest)
unlike the HQ and Keypad modules which only
learn tamper signals. Upon reception of the
learned signal the uRx will trigger a connected
device. Note that the uRx does NOT supervise the
radio link.
+12V, 0V, RxData RXO) and Trigger N/C) Pin-
outs are clearly indicated on the unit. The 2-way
dip switch is used to configure the polarity SW1)
and the Switch timing SW2). Another version the
uRxL should be used for latching requirements.
The I/O1 and I/O2 terminals are not used in this
device.
The raw data from the radio is also available at the
connector on RXO for connection to keypads or
other decoder devices.
The unit has 3 LEDs, one displaying RF data, one
showing the output NC) status and one used for
showing the status of the unit which will vary its
flash rate for different option settings.
Installation
Position the uRx in a position suitable for the
reception of radio signals from the intended
source. Check for radio interference by observing
the flashing of the RF LED. If the RF led is flashing
brightly and continuously then you may have a
problem with radio reception. Confirm this by
transmitting from a roboguard product to see how
the RF-led flashes for data reception.
Obviously the device to be triggered will need to
be located closely.
Wiring
Wire the uRx to +12V and 0V, ensuring the 0V is
common with the 0V of the device to be switched.
Wire the data line or the trigger NC)
outputs as needed.
The NC output is an open-collector low-
side driver capable of sinking 500mA continuously.
It can therefore be used to drive sirens, relays etc.
Should it be used as a data output then a typ 1k)
pull-up resistor will need to be used at the
connected device.
Coding
As you require the unit to decode a radio message
then you must teach the uRx the code of the
roboguard event by placing the unit into learn
mode and then transmitting the relevant signal.
The device is placed into learn mode by using a
conductor like a screwdriver) to short out the
program pads on the PCB. The program pads are
located next to the letter B on the PCB in the area
of the 2-way DIL switch.
The status led will now remain on until the device
learns a valid roboguard code. Transmit the
desired code tamper, remote or intruder). The
status led will reset back to flashing
If the unit is powered up with the programming
input shorted then the unit will erase all learned
codes.
Configuration
Place the DIL switches in the required positions as
per the information in the connected device’s
installer manual and the table below.

Testing
The installation must be tested for RF range and
for correct triggering of the connected device upon
transmission of the previously learned signal.

understanding of electrical systems and the
interconnection thereof. If you are not in this position
then we advise you contact an installer as you may
damage the product and void the Warranty.
