What is the acceptable adjustment range for field-adjustable smoke detectors?

The acceptable adjustment range for field-adjustable smoke detectors is less than 0.6 percent per foot. This specific threshold ensures that smoke detectors function effectively without being overly sensitive or underperforming. Precise calibration is crucial for rapid detection in the event of a fire, as it allows the detector to accurately assess smoke density and environmental conditions while minimizing false alarms.

Choosing an adjustment range that is too high could lead to compromised performance, where detectors might not activate under the necessary conditions. Hence, maintaining an adjustment range within this limit allows for optimal detection capability while adhering to safety standards and ensuring reliability in fire alarm systems.
