If the mounting location of smokes and heats gets higher, the listed spacing must be adjusted. True or False?

In fire alarm system design, the placement of smoke detectors and heat detectors is critical for ensuring effective operation and early detection of fires. The mounting height of these devices does influence their spacing requirements.

For smoke detectors, as the mounting location becomes higher, the effective area they are able to cover may change due to factors like airflow and the stratification of smoke. Generally, the spacing is calculated based on standardized guidelines that take into account the mounting height. Therefore, if smoke detectors are mounted significantly higher than the standard reference height, adjustments to the spacing between detectors are typically necessary to maintain coverage effectiveness.

Heat detectors also have specific guidelines regarding spacing based on mounting height. Much like smoke detectors, if they are installed at elevated positions, adjustments to spacing would be required to maximize their efficacy.

Given this context, the correct assertion is that the statement regarding the necessity of adjusting listed spacing if the mounting location becomes higher is indeed true. Proper installation and adherence to manufacturer instructions and codes ensure optimal performance of fire detection systems.
