Be fixed where they can be reached to maintain therefore not over the stairs.
Attic heat detector placement.
It gets very hot up there in the summer southern california so i thought it would be prudent to install a few high temperature heat sensors i bought 3 194 degree heat detectors.
They feature a detecting component inside the unit that activates an alarm when it reaches a predetermined temperature.
We recommend placing them high off of the ground or on the ceiling.
Install the first attic smoke detector on the wall near the stairs anywhere between the 4 inch and 12 inch marks.
Ceiling height construction and ventilation play significant roles in detector performance and must be considered when determining detector placement.
Ceiling mounted detectors should be located such that their sensitive elements are between 25mm and 150mm below the ceiling in the case of heat detectors or between 25mm and 600mm below the ceiling in the case of smoke detectors.
Regardless of where you place a heat detector these devices should be placed away from any vents or ducts that may interfere with their function.
The alarm will sound if temperatures rise above 135 f.
Spot type heat detectors should be selected so that the rating is at least 20 f 11 c above maximum expected ceiling temperature.
Heat detectors are sufficient for places where speed of detection isn t critical or in small confined spaces.
Another location in a home where you should have a heat detector rather than a smoke alarm is the attic.

However as i prepare to install them i wanted to get others.
