Title
Cargo Compartment Fire Detection Instruments (Turbine Powered Subsonic Aircraft)
Scope
This Aerospace Standard covers three basic types of cargo compartment fire detector instruments. <p> Basic Types - Definition of: <p> Type I: Carbon Monoxide, an instrument which will actuate an alarm signal when the concentration of carbon monoxide in air exceeds a specified value. <p> Type II: Smoke Detector, Electronic, an instrument operating on the principle of smoke particles modifying the relationship between a light beam and electronic light sensor which will actuate an alarm signal when the concentration of smoke in air exceeds a specified value. <p> Type III: Smoke Detector, Visual, an instrument which, by visual means, will show in a positive manner the presence of smoke when the concentration of smoke in air exceeds a specified value.
Rationale
This document has been determined to contain basic and stable technology which is not dynamic in nature.
