Purchased two door/window contacts for my existing wireless Smart Home Alarm IA-330. This alarm system was installed just over a year ago and works well. I wanted to add these two contacts to another door and another window, to extend the alarm system. I am very happy with the whole alarm system. It was so easy to install and set up. It is very easy to use too. The alarm hub is very small, but it makes a very loud noise when set off. The system was easy to set up on my iPhone too. I love being able to monitor the alarm system when I am away from home. Excellent alarm system and would happily recommend it.

The security system does exactly what I require. Excellent products. It took less than ten minutes to figure out how to set it up with code and fixtures, easy as abc. Thank you so much for your guidance to as which product was suitable fro my needs.

I would recommend your products to anyone. Thank you.

Bought this to replace a faulty one supplied with the original kit. Fitting was easy and product good quality. Working ok.

Excellent addition to my superb Yale security system. This one is being used 200 feet away from my house to secure a shed. It works like a dream. Yale and safe.co.uk a wonderful way to get peace of mind. To secure out buildings I would have liked a three zone system. But by putting the keypad in an unalarmed passageway and putting the outbuildings into the entrance zone we can part arm the alarm and have the outbuildings alarmed at all times. We have had the system in place for a couple of months now and the reassurance from being contacted by sms and email is so powerful. We purchased all of our alarm plus add ons from safe. Every question we have asked has been answered. We even ordered the wrong item and got a no quibble refund. I would not buy any other alarm than a Yale Sync and I would not buy it from anywhere else. We will be adding video to the system in the near future.
