PIR Detectors (ESD 1, 2 or 3)

Q: How long does the battery last in the ESD?

A: This will depend on the number of transmissions from the ESD - but a good quality alkaline battery may last up to 18 months. The normal current drain is 20 micro amps approximately.

Q: I have an ESD installed for some time and it has stopped working.

A: Check the batteries.

Q: Which ESD should I use to protect my back garden if I have small pets?

A: The ESD3 would be suitable. When mounted at 2.5 metres it will not see below approximately 1 metre. The detection range is 12 metres.

Q: How can I use the ESD2 to protect my garden fence which is 40 metres long?

A: Mount the ESD2 about 0.5 metres from the fence and at a height of 2.5 metres so that it looks along the fence line.

Q: How do I reduce the chance of false alarms from my ESD detector?

A: Try to mount the ESD so that there are no bushes or tree branches which can move in the wind and may be “seen” by the detector. The 40 metre ESD2 is more sensitive to such movements.

Q: What is the correct position for mounting the ESD?

A: Mount the detector so that people walk across the direction in which the detector is pointing. If someone moves towards or away from the detector the detection range is reduced.

Q: My ESD1 is giving false alarms from the tree branches in my neighbour’s garden.

A: The lens occluder label which came with the ESD1 can be used to cover part of the lens so that the detector cannot see the branches.

Transmitter (EST1)

Q: How can I use the EST1 to control a remote light?

A: The EST1 is connected to a wall switch. The wall switch is only used to connect two of the wires, one blue the other white, on the EST1. DO NOT CONNECT THE EST1’s blue wires or white wire TO LIVE, SWITCHED LIVE OR NEUTRAL or any other voltages or it will be damaged beyond repair. The ESR1 is connected to the remote light. Click here for more details.

Q: How is the EST1 powered?

A: 2 x AAA batteries for the latest model.

Q: How much current does the EST1 take?

A: The EST1 takes 2 to 12 micro amps approx. quiescent current.

Q: When the switch is closed is the EST1 transmitting all the time?

A: No, the EST1 transmits for 1 second approx. when the switch is closed or opened.

Key Fobs (ESF1 & 4)

Q: What type of battery is used in the ESF1/ESF4?

A: It is a 23AE 12 volt battery.

Q: How do I open the key fob to change the battery?

A: Remove the screw on the back. The front of the key fob is in two halves. Push the two halves apart and upwards.

Q: How do I improve the transmission range?

A: Hold the key fob with the buttons towards you and high up.

Receivers (ESR1 & 4)

Q: The ESR1 will not learn the code sent by the ESD, EST1 or ESF4 when I am using the 9 volt battery in step 2 of the installation instructions.

A: 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.

Q: I had a power cut and my ESR1 stopped working.

A: 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 from the ESD, EST or ESF again.

Q: I have completed the range test with the 9v battery When the ESR1 is connected to the mains supply the relay on/off LED lights when there is a transmission but the lights do not come on.

A: Make sure the 9v battery and the red and black wires are removed from the green terminal block in the ESR1 before the mains supply is connected.

Q: Is there an external aerial available for the ESR4?

A: The AE434 can be used with the ESR4 but not the ESR1.

Q: What is the difference between the ESR1 and ESR4?

A: The ESR1 has one volt free relay for switching but the ESR4 has four MAINS VOLTAGE switching relays which will give 230 v ac as an output.

Q: Is there a 12v version of the ESR1?

A: Yes, the ESR2.


PIR Detectors

Q: I want to use 4 Genesis wireless PIRs. Which receiver products do I need to connect to a dome camera with 4 pre-sets?

A: The LGMRU4x4 has a masthead receiver and relay card in a single product. The relay card has 4 alarm relay contacts and 4 tamper relay contacts.

Q: How and when do I use subnet codes?

A: You only use subnet codes if there are one or more repeaters on the site. If there are only detectors and a LGMT434 masthead with LGRU16 relay control unit or LGMRU4x4, then leave the subnet on the PIR as 1 and on the LGMT434 sub A=1 sub B=1. Click here for more details.

Receivers (LGMT434, LGMRU4x4, LGIPMT434)

Q: How many detectors can be used with one LGMT434?

A: 64.

Control Units (LGRU16, LGRM8)

Q: What are the pin definitions of the 40 way ribbon cable on the LGRM8?

A: The IDC connector has a small triangle on one side which denotes pin 40. The wires on the ribbon cable are grouped so that there are 5 wires for each PIR and 8 PIRs in total for one 40 way ribbon cable. Pin 1=alarm common, pin 2=alarm normally closed contact, pin 3=alarm normally open contact, pin 4 & 5 tamper pair, normally closed. When the power is OFF pins 1 & 2 will read zero ohms but pins 39 & 40 will be open circuit.

Q: Why does the display on the LGRU16 show continuous alarm for PIR “x”?

A: The display will keep showing the unit number of the last PIR which was in alarm.

Q: What is an E1 error?

A: The right hand LGRM8 is missing.

Q: What is an E2 error?

A: There is no communication between the LGRU16 and the LGMT434.

Q: What is an E3 error?

A: The LGRU16 has been programmed to a different group to the units learnt. For example switch 4 is on switch 3 is off so the group is 17 to 32 but the learnt PIR unit numbers are 1 to 16. It can be cleared by pressing the front panel green button after setting the correct group.


System Requirements

Q: What other equipment do I need?

A: None.  OCULi  is a stand-alone PIR camera that requires no power or alarm panel. Just activate your SIM and register on the OCULi web portal You can also use your mobile phone with the free IOS or Android app.


Q: Can I use my own SIM?

A: OCULi works using passive IR detection so if there is no movement it is inactive.  Once movement is detected it establishes a connection to the network server in order to send the images.  Wireless Logic SIMs have proven to be the most stable in all our testing so we do not recommend other SIMs at this time.

Q: My SIM is not working.

A: Have you completed a Direct Debit form for Wireless Logic?  Your SIM will normally be activated within 24 hours of the form being submitted.  You should also check that you are on the correct tariff for the number of activations you are experiencing.

Q: Can my SIM data be pooled if I have several units?

A: Yes. So if you have 10 units, each with 10MB of data then you have an aggregated data allowance of  100 MB which can be shared between the OCULi units.  Unused data cannot be carried forward to the next month.

Q: Will my SIM work abroad?

A: We use EU roaming SIMs to ensure that the best signal is picked up, regardless of provider throughout the EU.  For anything outside of the EU please speak to the help desk.


Q: How do I know my OCULi unit is working?

A: Once your OCULi SIM has been inserted and activated, the unit will start up in 15 – 30 seconds.  It will make a connection to the server, generate a camera in your portal and upload a series of pictures – this is an initialisation event flagged with a yellow alert. 

Q: How quickly will I receive notification of an intrusion?

A: We use PUSH notification for the delivery of images to your mobile phone so as long as you have a good 3g signal you will receive the images in seconds.

Q: My alarm events keep flashing – how do I stop this?

A: You must sign off the event as actioned. Click on ‘Clear event’ at the top of the footage and mark as read.  There is a space for a message if needed.


Q: How long will the batteries last?

A: About a year with normal use.  You can use our usage calculator to estimate your battery and data usage according to your expected number of alarm events.  This is available on our DOWNLOADS section at  Please note that enabling features such as the Timeline® will affect the life of the batteries.  Unit Management has a number of power saving modes you can use to enhance battery life.

Q: What batteries should I use?

A: OCULi is supplied with 2 x specialist high capacity lithium D cell batteries.  These are the only type of battery that should be used with OCULi.  Replacement batteries can be ordered using the code LOBP1.


Q: How do I receive any software updates?

A: We provide over-the-air updates so when your unit next sends a heartbeat, it will automatically upload any new software.

Integration with other platforms

Q: How do I integrate with another platform such as IMMIX?

A: Go to the Sites tab on the OCULi portal and click on Platform Integration.  There is a drop down list of all available integrations.  Choose the platform and fill in the required information.  For help with this feature click on the Info tab.

Q: How do I integrate with WEBEYE?

A: If you have purchased your unit via VDT or Webeye, full details will be sent with your unit, otherwise you can contact the WEBEYE team on 0115 714 9999.
