JC 433MHz Security Wireless DIY Standalone Alarm Siren Kit Multi-Function Alarm Host with PIR Detector, Door Window Sensor, Remote Controller, Water Leakage Sensor and Warning Sticker

I purchased alongside the "JC Wireless GSM & WIFI Security Alarm System, Home and Business RFID Burglar Security, Support Auto Dial, Multi-language GUI and English APP Control , with Pet-friendly PIR Detector, Door Window Sensor,Remote Controller, RFID Tag, and Warning Sticker". It is a great piece of kit but I ordered it thinking it would work with the above alarm system as it did not come with a siren, and I assumed the siren could be mounted outside. It is for indoor use, don't get the reason for it being inside but never mind. So not negative about the product, just my miss-understanding.It can be used as a standalone system, might be good for a flat, shed, garage or something like it.It looks modern, I used the door sensors and sensor with the above alarm system and it all worked well, was simple to pair.Great customer service.

Initially a little difficult to set up following just the instructions, the You-Tube video is a great help, you have to link each trigger with the hub by turning on a trigger and the hub, press the little "set" button on the round hub until it makes a bleep then operate the trigger, say the motion detector, you move you hand across is whilst the hub flashes really quickly a couple of times, gives 3 bleeps, then they are linking, you have to do that with every item including the fob. I like the way you can have a window open, set the alarm, and the alarm will still cover the rest of the triggers even though that particular window doesnt have the contacts touching.

simple install worse you learn how to marry components to the control box. Alarm is quite loud and may scare an intruder but unlikely to bring anyone down the street to investigate (perhaps someone next door might hear)came with a movement detector to cover one room and two contact switches that can cove two doors or windows.worth the money giving some piece of mind. blue light flashes on main unit which is also the alarm. seems to do what it says so i bought a second one

Works great synchronised with full kit and external siren and surprisingly easy to set up, had 3 different types of this sort of kit but definitely the best so far and looks like a very expensive system when installed. Great product thanks

Wireless connection but is not clear at first you have to keep this in power supply at all time.
