Smoke and heat detectors should not be installed in areas known as "dead air space." What is the minimum distance they should be from any corner?

Smoke and heat detectors are crucial for effective fire safety, functioning best when they can detect rising smoke and heat quickly. In areas known as "dead air space," which often occur in corners where airflow is restricted, the performance of these detectors can be compromised. To ensure optimal functionality, detectors should not be installed too close to corners, as this can hinder airflow and reduce their ability to detect smoke or heat promptly.

The minimum distance of 4 inches from any corner is established to avoid these "dead air space" zones. This distance helps maintain an adequate airflow around the detector, enhancing its response time to an actual fire situation. Proper installation spacing is critical to ensure that smoke and heat can reach the sensors effectively, minimizing the risk of delayed alarms that could potentially lead to hazardous situations.
