We know we will never convert all installers as you will stick to what you know, at the end of the day we set the complete system up in advance, test all features then box it up and deliver it to the buyer on a next working day delivery, meaning the buyer just has to secure the sensors in the required locations and power it on. Most installations will take a client around 1-2 hours from scratch, and therefore means as an installer you cannot charge a great deal for the installation. Therefore a system that is quick to install is not good news for some. Anyhow I have a bottle of beer with my name on it. I will post the list tomorrow of EN approvals. Anyone interested give us a call or drop us an email and we will be more than happy to help, however I have already stated they are not made in China, but many top quality products come from china.....nearly all TV, DVD, IPhone, IPad, cars, quite possibly the sofa you are sat on, the Device you are reading this post from, the lights in your room, the list could go on. And yes lots of total rubbish as well, but the Gamma7 does not. Come on guys I've made this clear...each product is boxed and bar coded with a stamp where they are made, each panel has a serial number linked to the box it is in. They are a quality device, that works well, and so far no complaints.
