Question

A fire alarm usually detects smoke in case of fire. Electrician was told to fix the fire alarm on
the ceiling. Give reason why it is important to fix it on the ceiling only?

​

Answer 1

This is because air does not circulate effectively in corners, and objects like light fittings can obstruct smoke and heat from entering the sensor chamber. As hot smoke initially rises and then spreads out, smoke alarms should be located on the ceiling.

Answer 2

the air on top of the fire becomes hot and rises up so it is important to fix fire alarm on the ceiling
