Set Wireless Linkable Smoke Detector 3x SA-33 Alecto
This is a set that consists of 3 smoke alarms. These smoke detectors can be connected to each other wirelessly. That means that if one goes off, then the other 2 smoke alarms will ring. So you can ensure that the alarm is heard throughout the house.
Do you have 3 smoke detectors not enough to complete your house with these smoke detectors. Then this set is always expandable with separate smoke detectors that you can add to your installation. It is of course also possible to use all smoke detectors separately.
