ARP4001B - Lavatory Smoke Detectors

Document Number: ARP4001B
Revision Number: B
Lavatory Smoke Detectors
The purpose of this SAE Aerospace Recommended Practice (ARP) is to describe key features that should be incorporated in the lavatory smoke detector system. Consideration has been given to existing requirements of the FAA and to recommendations of aircraft operators and manufacturers. This document is deliberately not specific in all areas in order to maximize the freedom to use state-of-the-art design and manufacturing technologies. Safe, reliable, and effective lavatory smoke detectors remain the primary goal of the document. The intent of installing smoke detectors in aircraft lavatories is to enhance, through auditory and visual signals, the ability of flight attendants to detect fires in the cabin, and not to serve as primary detectors such as those used in isolated cargo compartments.
