MIL-PRF-32227, PERFORMANCE SPECIFICATION: FLAME DETECTOR ZONE MODULE (FDZM), SWITCH CLOSURE ZONE MODULE (SCZM), AND ISOLATOR, ADVANCED FIRE AND SMOKE SENSOR SYSTEM (AFSSS) (25 OCT 2006)

MIL-PRF-32227, PERFORMANCE SPECIFICATION: FLAME DETECTOR ZONE MODULE (FDZM), SWITCH CLOSURE ZONE MODULE (SCZM), AND ISOLATOR, ADVANCED FIRE AND SMOKE SENSOR SYSTEM (AFSSS) (25 OCT 2006)., This specification covers the performance requirements for Flame Detector Zone Modules (FDZM) (see 6.8.6), Switch Closure Zone Modules (SCZM) (see 6.8.16), and isolators (see 6.8.9) and their respective enclosures, which are components of an overall Advanced Fire and Smoke Sensor System (AFSSS) for use on naval ships. These devices may be of commercial-off-the-shelf (COTS) design, but must be rugged (see 6.8.13) enough to meet all of the requirements of this performance specification and the rigors of Navy shipboard service. Performance requirements for the other associated AFSSS components (e.g., ionization (see 6.8.8) and photoelectric (see 6.8.10) smoke sensors (see 6.8.15), heat sensors (see 6.8.7)
