Honeywell Morley S200A Photo-Thermal Detector with Isolator (MI-PTSE-S2I-IV)

The MI-PTSE-S2I-IV is an intelligent multi-sensor addressable fire detector in an ivory finish designed for commercial, industrial, and institutional safety installations. The plug-in detector head combines an optical light-scattering chamber with a 58°C fixed and rate-of-rise thermal sensor, analyzed via internal software algorithms to evaluate thermal and smoke signatures simultaneously. An integral short-circuit isolator automatically isolates loop short circuits, preserving communication across the remainder of the signaling line circuit. Featuring mechanical rotary decade switches for address configuration (01 to 159), tri-color 360-degree status LEDs, and compatibility with Advanced Protocol (AP) and CLIP protocols, it complies fully with EN 54-5, EN 54-7, and EN 54-17 certifications.
