Are smoke detectors allowed to be installed in an air stream?

Smoke detectors should not be installed in an air stream because doing so can lead to inaccurate readings and delayed responses to smoke. When a detector is placed directly in the path of air movement, it may constantly receive clean air, preventing it from sensing smoke effectively. This can compromise fire detection and safety, as the primary function of smoke detectors is to identify the presence of smoke quickly and reliably.

In addition, air currents can also interfere with the smoke particles, dispersing them away from the detector rather than allowing them to reach it. This could lead to a situation where a fire is not detected in a timely manner, posing a significant risk to life and property. By following the guidelines that advise against installation in an air stream, safety is maximized, ensuring that smoke detectors function as intended.
