What is the recommended height for mounting heat detectors on a wall?

Mounting heat detectors at a height between 4 and 12 inches from the ceiling is recommended due to the way heat rises in a room. Since hot air tends to accumulate near the ceiling, positioning the detector within this range allows it to effectively sense rising temperatures indicative of a fire. This height also takes into account the need for the detector to be within an optimal range to ensure it can respond to heat efficiently without being too close to the ceiling, where it might get inaccurate readings due to stratification of heat layers.

Using this recommended height helps ensure that the heat detector performs its intended function effectively, providing an early warning in the event of a fire. Mounting it at incorrect heights could lead to delayed detection or false readings, which could compromise safety.
