FAQ

PIR Detectors

How long will the batteries last in my ESD detector?
With normal use and a good quality battery, you can expect to see at least 18 months of battery life. More frequent transmissions will affect battery life.
    What batteries should I use in my ESD detector?
    ESD detectors use a 9-volt lithium battery
      Which ESD detector should I use if I have pets?
      The ESD.3 features a 12m horizontal curtain lens which is ideal for use with pets. When it is mounted at 2.5 metres it will not see below approximately 1 metre.
        How do I reduce false detections?
        Make sure that the detector is positioned so that there are no bushes or tree branches that can move in the wind and 
          How high should I mount my ESD detector?
          The ideal mounting height is 2.5 metres.
            What position should I fit the ESD detector in?
            Position the detector so that people will walk across the direction that it is pointing. 
              How can I protect my perimeter fencing?
              The ESD.2 features a narrow range 40m beam that is ideal for perimeter detection. Mount the detector around 0.5m from the fence at a height of 2.5m and have it look along the fence line. 
                Can I mask the lens?
                Yes, you can mask areas of the lens with the lens occluder labels which are included in the box. These are useful for masking off areas that may view moving objects like tree branches or busy areas like roads.
                   

                  Transmitters

                  What batteries should I use in the EST.1?
                  2x AAA batteries
                    How long will the batteries last in the EST.1?
                    With normal use, the batteries should last approximately ___ months/years
                      How much current does the EST.1 take?
                      2 to 12 microamps
                        When the switch is closed, is the EST.1 transmitting all the time?
                        No, the EST.1 transmits for 1 second when the switch is closed or opened.
                          How can I use the EST.1 to control a remote light?
                          Fit the EST.1 inside a wall switch as demonstrated in the instructions. Do not connect the EST.1 wires to live, switched live, neutral or any other voltages or the unit will be damaged beyond repair. Connect an ESR.1 to the remote light.
                            What batteries should I use in the ESF.1 and ESF.4?
                            The keyfob uses a 23AE 12-volt battery
                            How do I open the key fob to change the battery?
                            Remove the screw on the back and push the lower half of the casing down to slide it off.
                              How do I improve the transmission range?
                              Hold the key fob with the buttons facing upwards and towards you and lift it higher.
                                 

                                Receivers

                                What is the battery used for in the ESR.1?
                                The 9v battery included with the ESR.1 is used for range testing only and must not be left inside the unit.
                                  Is there an external aerial available for the ESR.4?
                                  Yes, the AE434 aerial can be used with the ESR.4 but not with an ESR.1
                                    What is the difference between the ESR.1 and ESR.4?
                                    The ESR.1 has one volt-free relay for switching and the ESR.4 has four mains-voltage switching relays which will give 230v ac as an output.
                                      Is there a 12v version of the ESR.1?
                                      Yes, the ESR.2
                                        Can I dim lights with an ESR.1 or ESR.4?
                                        No, you cannot dim lights with either receiver as they can only operate on/off switching.
                                          I had a power cut and my ESR.1 stopped working.
                                          Flush the memory by pressing and holding the learn button. The learn LED will come on and then turn off after about 10 seconds. After this, try to learn the code from your transmitter again.
                                            The ESR.1 will not learn the code sent by the ESD, EST.1, ESF.1 or ESF.4 when I am using the 9v battery in step 2 of the installation instructions.
                                            Flush the memory of the ESR1 as follows – press and hold the learn button. The learn LED will light and about 10 seconds later it will go out. Try to learn the code again. The 9 volt battery must be able to provide enough current to operate the circuit. If the battery is partially drained get a new one and try to learn the code again.
                                              When the ESR.1 is connected to the mains supply, the on/off LED on the receiver turns on but the connected lights do not.
                                              Make sure that the 9v battery used for range testing and the red and black wires are removed from the green terminal block inside the ESR.1 before the mains power supply is connected.
