What is the required clearance for smoke sensors from the sidewall?

The required clearance for smoke sensors from the sidewall is at least 4 inches. This distance ensures that smoke can reach the sensors effectively without obstruction. Placing the smoke sensor too close to a wall may impact its ability to detect smoke accurately, as walls can deflect smoke away from the sensor. Adhering to this guideline is crucial for optimal performance and responsiveness of the smoke detection system. The specified clearance helps ensure that the sensor operates within the manufacturer's specifications and regulatory standards, which are designed to maximize occupant safety in the event of a fire.
