RoboGuard uRx User manual

uRx Manual 1
UNIVERSAL RECEIVER (uRx)
General Operation
• The uRx is used as the receiver for the
Keypad and uTx (Repeater Station).
• The Universal Receiver (uRx) is also used to
remotely trigger the operation of electronic
devices using Roboguard signals.
• The uRx can be “taught to respond to any
particular roboguard radio signal – Tamper,
Intruder, Auto-test and Remote Tx.
(Intruder and Remote are the most
common).
• Once the uRx has learned a roboguard code, every time it receives
that radio signal, it will respond by triggering a connected device.
• This connected device may be an alarm system, a camera system,
a siren, an SMS module, a timer relay - in fact any device capable
of being triggered by an electronic signal.
• For example, the uRx can be programmed to respond to a radio
signal from a Roboguard handheld remote. This handheld remote
can then be used as a panic button and the uRx can be used to
trigger an SMS module to send an sms call for help in response to
the panic signal.
• Other popular uses include operating garage doors, switching on
external lights and triggering a strike-lock.
• The installer must connect the uRx to a 12V-power source and to
the device that you wish to trigger.
• The installer must also configure the options on the uRx to correctly
trigger the connected device and must program the transmitter into
the uRx through a learning process.
Installation
• When used as a data receiver for the uTx (repeater) or Keypad,
connect 12 volts and 0 volt to the terminals.
• Connect the data output (RXO) terminal to the Data/RXD input
terminals on the Keypad/uTx. (see Repeater Station in this manual)

uRx Manual 2
• The uRx will learn ANY roboguard signal - Tamper,
Intruder, Auto-test and Remote Tx, unlike the HQ and Keypad
modules, which only learn tamper signals.
• Note that the uRx does NOT supervise the radio link.
• +12V, 0V, Rx Data (RXO) and Trigger (N/C) terminals are clearly
indicated on the unit.
• The I/O1 an I/O2 terminals are not use in this evice.
• The 2-way DIPswitch is used to configure the polarity (SW1) and
the Switch timing (SW2).
• The uRx will deliver a 2-second pulse or a 5-minute pulse,
depending on timing configuration. (A latched version, the uRxL is
also available, for latching requirements)
• The unit has 3 LEDs, one displaying Status of the unit (it will vary
its flash rate for different option settings), one displaying RF data
and one displaying output.
Position the uRx in a position suitable for the reception of radio signals
from the intended source.
Obviously the device to be triggered will need to be located nearby.
(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).
Wiring
See wiring Diagram Below.
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, use a (type 1k) pull-up resistor at
the connected device.

uRx Manual 3
Co ing
The device will learn any Roboguard code transmitted while in learn
mode.
Activate learn mode by using a conductor (like a screwdriver) to short
out the program pads on the PCB.
The program pads are located between the letter B and the 2-way
DIPswitch on the PCB. (See below)
The status LED will now remain on (solid) until the device learns a valid
roboguard code.
Transmit the desired code (Intruder, tamper or remote).
Remove the conductor.
To confirm the coding, activate the programmed device and check the
output LED
Note: To send an intruder code, trigger the top and bottom PIR on the
Roboguard while the uRx is in learn mode.
When the code is learned, the status LED will reset back to flashing.
Note: If the unit is powered up with the programming input shorted,
the unit will erase any learned code.
Configuration
Place the DIP switches in the required positions as per the information
in the connected device’s installer manual and the table below.
Function Switch 1 - Polarity Switch 2 - Trigger Time
ON N/O 5 minute pulse
OFF N/C 2 second pulse
