Smoke, gas and water leak detectors
A smoke alarm must first meet the current European standard; beyond that, models differ by battery, sealed so you never think about it again or replaceable. Connected versions alert you remotely and can sound together throughout the house, a real advantage over several floors. A gas detector is chosen for the gas actually used at home, and a water leak detector sits on the floor near appliances at risk.
