Easy to Setup and Ready to Go
The Lynteck LS400 Wired Intruder Alarm Kit comes supplied with everything you need to set it up in the box. The kit comes with four sensors which can be used on doors or windows, two PIR sensors as well as all the screws, fixings which are required (backup batteries for the control panel are not included Order Code L43AL). The patented two wire system means there is no polarity on the wires making for even easier installation.

What is home mode?
The Lynteck LS400 Wired Intruder Alarm Kit can be fully armed or part armed in home mode which allows you to program some sensor to switch off so you can more freely about the home whilst still being secure outside. Sensors can be manually set as to whether they are on or off in home mode allowing you all the flexibility you need.

Can I add to the alarm?
The Lynteck LS400 Wired Intruder Alarm Kit can be connected to a range of additional sensors and accessories giving you the flexibility to protect every part of your property. The Lynteck LS400 Wired Intruder Alarm Kit can be expanded to utilise up to four PIR sensors and multiple door and window sensors. The system is completely wired with tamper detection alarm meaning that if an intruder attempts to cut the wire or open a sensor the alarm is triggered so you can rest easy knowing that your property is secure.

Rated 3 out of 5 by from This is a good product for the price. I don't think the installation was straightforward for someone who does not do regular DIY but after some careful reading, I was able to put it all together. I found that the sensitivity it is usually set to is not really good enough at all. I have one of my PIR's directly facing a door and two of us were able to literally walk past it into my living room without it setting off. I understand there is a way to change the sensitivity but I did not find this obvious from the instructions initially but will have to review this. Hopefully should do the job well once changed.

Rated 4 out of 5 by from Second order for this system arrived promptly. First one was straightforward to install from the clear and detailed manual and has worked well. Only puzzle was how to replace reserve batteries without triggering the "tamper-alarm" ! Only two minor niggles: (a) Rechargables seem to show "battery low" from day one, so must test sometime soon. (b) max of 4 PIRs - 2 on each of 2 zones - but actually enough for me !

Rated 3 out of 5 by from Alarm I haven't fitted alarm as yet. However when opening the box I noticed a plug in power adaptor. I was expecting to hard wire into the mains. This power supply was not mentioned in the description or shown onntje image

Rated 4 out of 5 by from Dead easy install Installed the alarm last week. Really simple. Easy instructions. So far the only niggle is it doesn't always recognise the disengage code so sometimes have to enter it twice to deactivate the alarm. So far have always managed to disengage it before the alarm goes off. Wiring is easy as you can't get the wires the wrong way round.

Rated 4 out of 5 by from Good value and very clear fitting instructions I was impressed with how much was in the kit for the cost. It seems very good value for money. I am using it to protect a shed so I didn't need all of the components. The fitting instructions were very well written. The main limitation for me is that the external siren has no battery backup. So all an intruder would have to do would be to pull the wires out and that would silence it. First couple of weeks use has been OK except that when disarming the system on entering the building by tapping in the 4 digit code it doesn't give a bleep after you push each number on the keypad. So sometimes it has taken me three attempts to put the number in before the system would disarm. So far I've always been able to turn it off before the alarm goes off but I'm not convinced that will be the case if and when the keypad becomes worn.

I bought this unit but find that there is no flashing alarm light, only a siren. The bell-box looks like it lights up but it does not. Is there an add-on available to get a flashing light?

Hello and thank you, but the LS400 is not on the list of compatible control units.   LS400 is a two-wire system. In the Qs for the Vortex box there is an answer that says it is not compatible with the LS400:- -------------------------------------------- "DanB  · a year ago   Can this be connected to the wired LS400 security alarm system? 1 answer Les  · a year ago   NO .. you need a 2 wire bell box ... ---------------------------------------------------

When i put on Switch at Position 2 the alarm go off y went to pir connection to it

Asked by: Ishy000
Position 2 should only be used when you are using 2 PIR sensors on the same zone and should only be connected while the mains adapter and backup battery supply are disconnected. Attempting to connect sensors while either power supply is fully connected will trigger the tamper alarm.

Can I put another sounder on this system?

Asked by: Andy
This unit only has one terminal set for an external siren, as such we cannot guarantee compatibility for additional sounder units.

Just bought this alarm package for the garage. I don't need to use the pir detectors. Therefore, do I just connect their terminals in the control unit with a short piece of wire ? Can I use the other door contacts on the pir detector conectors instead ?
