Introduction

A Keyring radio signaling system similar to car central locking or garage door automation can be used to remotely activate or unset an electric security fence from up to 200m away from the energizer monitor unit (EMX).

This is a convenience for the users of the electric Security fence and can also be a significant cost saving option for systems installers.

Electric security fences are often installed some time after a factory has been built, and usually there will be a concrete or tar sealed yard and some distance between the EMX location and the Entry / Exit gate of the property. The remote control avoids the need for expensive concrete cutting and conduit to wire to a key switch at the gate itself.

Each remote control unit is uniquely coded so neighbouring systems cannot interfere with the fence control, and up to 20 different Keyring controllers can be used on an individual system.

On remote controlled security fences a fence light is usually installed at the gate to indicate to the user that the fence is active or unset. When armed the fence lights flash with each pulse from the EMX, and apart from such status indicating are also useful as an additional deterrent to would-be intruders.

While it is possible to operate the remote control receiver with any of the EMX models it is best used with those without the cabinet key switch - i.e. the Speedrite SX010-01.

The remote control unit is in two parts:

• RX-1 / ASH Single Channel Remote Control Receiver

• CXTRO2 Two button Keyring Remote Control Transmitter – 303 MHz

RX-1 / ASH Single Channel Remote Control Receiver fitted to an EMX

Programming and Operating Instructions

The RX1 receiver is designed to operate with ASK or OOK radio transmitters working in the 303 MHz frequency band. The RX1 is a single channel receiver and can store up to 20 radio key codes all of which operate relay output RL1.

Learn Mode

To programme a Keyring transmitter into one of the 20 memory slots you must first get into “Learn Mode”. To do this you need to press the “Learn” button located on the lower right of the PCB.

Start by pushing the button momentarily – press and release in less than a second. This will bring you to Slot #1.

After two seconds LEDs 1 will flash once to indicate code Slot #1.Two seconds later “Learn Mode” is indicated by LEDs 2 and 3 flashing together, and will continue to do so for up to 30 seconds.

In this time pick up Transmitter 1 and push the larger of the two transmit buttons to establish the identity as Code Slot 1 transmitter. The two LEDs stop flashing to indicate a successful transaction.

Experience has shown that it is better to jump from code 1 to code 3 so for the next transmitter recommence the routine by pushing the “Learn” button three times to bring up code Slot #3. When the two LEDs start flashing push the button on the second transmitter to establish the code.

Repeat the procedure pushing the “Learn” button the same number of times as the code to be programmed.

To exit Learn Mode push the “Learn” button for longer than 2 seconds.

EMX Programming

If the EMX is to be used just with the remote switching device (as opposed to also having a keypad or key switch attached to the unit) then the gate key switch mode “On / Off” option has to be enabled.

Enter the following on the keypad:

MPIN - Program - 6- 6

 It is a good idea to have an additional arming device on the system such as a keypad or key switch. Not only is it a back-up in case the remote transmitters are lost or damaged but it also gives the customer a reassuring visual indication of what is happening with the fence system.

If such devices are added in order for them to work as well as the remote system the gate key switch mode “Arm / Disarm” option has to be enabled.

Enter the following on the keypad:

MPIN - Program - 6- 5

 Operation

 In normal mode LED1 turns on every time a signal is received. If the signal matches one of the stored code slots then the relay will also turn on. With the jumper removed it will remain in that state until another valid signal is received i.e. the system will remain armed or unset as the case may be.

Field experience shows these units capable of operation up to 200m away from the receiver; however local site conditions and the location of the EMX can influence performance. The range can be much reduced if the unit is screened by metal or the reinforced concrete of a building. Alternatively it is possible to attach a coaxial cable to the “ANT” terminal to both clear any such screening and increase the effective range of the system.
