Smoke alarms and smoke detectors must comply with which applicable standard for normal environmental conditions?

Smoke alarms and smoke detectors are crucial components of fire protection systems, and their design and performance standards are established to ensure reliability and safety. The applicable standard for smoke alarms and smoke detectors in normal environmental conditions is ANSI/UL 268. This standard specifically addresses the safety and operational effectiveness of smoke detectors used in various environments, focusing on their response to smoke and potential fire conditions.

UL 268 outlines the requirements for construction, performance, and testing to ensure that smoke detectors respond accurately to the presence of smoke, minimizing false alarms while ensuring reliable performance during a fire. Compliance with this standard confirms that a smoke detection device meets the necessary criteria for effective hazard detection under standard operating conditions.
