Measure the distance between the mounting holes on the mounting bracket before making the holes to be drilled in the ceiling.
Once you are done with the measurement, drill small holes according to the measurements after using a drill machine and the ladder. If the smoke detector is wireless, you must connect it to a network after carefully reading the given instructions.
Attach the mounting bracket to the ceiling with the help of screws and place the detector into the bracket. Keep turning the smoke detector clockwise until it stops.
After attaching it to the ceiling make sure that you have placed the required amount of batteries in the battery holder. Don’t forget to check if the batteries are working properly after pushing a test button on the smoke detector. Most devices usually have a warning signal that indicates when to change your batteries. However, it is recommended that you should change the batteries twice in a year.
If there is more than one detector in the room, the distance between the sensors should not be more than 9 meters. This rule is valid for a ceiling up to height of 3.5 meters, provided that there are no elements in the ceiling (beams, decorative elements, etc.), which can prevent the overflow of smoke.
