I bought this alarm 8 months ago fo£180. It's been brilliant. Not one false alarm. Easy to set up and use and would highly recommend as a deterrent. (Not as a insurance reducing alarm). Usually £200 but I noticed that this is £149 on Tesco with free click and collect.

Also this price on Amazon as well with free delivery.

Please don't turn this into a debate about getting a wired vs wireless alarm.

I highly recommend this as an owner.

Still going well with 2 house moves, like op said easy to install with step by step guide with dvd. Good alarm package.

Does this have anti-jamming capabiliy? These wireless alarms are easily jammed or bypassed with a broadcasted code grab if not, rendering them useless.

It has something you need to enable. Also states this from the website.

868MHz is one of the most secure frequencies for alarms systems – it gives 1 million unique codes compared to 250 from a 433Mhz, reducing the chance of interference, signal jamming and hacking from other devices.

And from the instruction manual


JAMMING DETECTION
In order to detect any attempts to illegally jam the radio channel used by your alarm system, a special jamming detection function is incorporated into the Control Panel. If this feature is enabled, an alarm will be triggered if the radio channel is jammed continuously for more than 30 seconds or if the system is jammed for more than 3 periods of
10 seconds in a 5 minute period. At full alarm it will beep for 3 seconds and will alarm after 10 seconds, at Part Arm it will beep for 3 seconds.
