Ceasefire considers the following three aspects to answer this question :

• Spacing

• Coverage

• Installation

It is also essential to understand the distance at which detectors are placed. Once this distance at which detector are placed. Once this distance is determined, we calculate the distance between detector and boundry walls. These distance are usually affected by factor such as partitions, beams,etc.

​

​

Installation Norms

Ceiling beams , partitions, hanging chandeliers, ceiling fans,etc..often reduce the Smoke Detector's effectiveness. Hence , Smoke Detectors must always be kept away from such obstructions.

​
