We at Spring Chicken think that the WST-630 is simply fantastic. It's a brilliant fire alarm system that's child's play to install - the baseplate is screwed in with two fixings! The network system is really clever too. If one alarm goes off, they all do, so if you've installed a few alarms, you can hear it from anywhere in the house. The modern design blends in well with the rest of the house, so it looks great. It really is a lifesaver!
