This product is our choice for a connectable smoke detector.
The Alecto SA-43 is a set of 3 wireless, connectable smoke detectors. You'll immediately have enough smoke detectors in your home for every floor. Link the detectors together. They have a range of 20 meters between them. Each detector works on 2AA batteries (with a lifespan of 5 years), so you'll be able to place them anywhere in the house. When the battery is (almost) empty, you'll hear a loud beep. In case of a smoke detection, an audio signal of 85 decibels will sound. Are you having a dinner party at home and is it not convenient for the smoke detector to be on at that specific moment? Simply switch it off temporarily with the time-out button. Via the test button, you can test the smoke detector to make sure that it works.
