 We have smoke alarms throughout our household because we live in a bushfire danger area. Plus we have an open fire. Smoke alarms we believe could help to save our lives. We have them in all the bedrooms and in our lounge room. But this particular one is slightly different. It has extra features to which I'll take you to and show you now. It is for hearing people with hearing difficulties. And it has a strobe light effect which is this contraption here. And it has a vibrating pad which goes off. So I'll push the test button for you and you can see and hear how it goes.
