Description
The Honeywell FS7-2173-2RP is a high-performance, unitized multi-spectrum infrared (IR) and visible electro-optical fire detector. Specifically designed for semiconductor clean room applications, such as wet benches, it provides a sophisticated two-stage response to detect both hydrocarbon and non-hydrocarbon fires with high immunity to false alarms.
Product Introduction
The Honeywell FS7-2173-2RP is a standalone fire detector that incorporates advanced digital signal processing (DSP) algorithms. Its “unitized” design means it includes discrete relay outputs, allowing it to operate as an independent device or interface directly with any approved fire alarm control panel. The FS7-2173-2RP Flame Detector features a rugged, leak-proof polypropylene housing that is resistant to the acids and chemicals typically found in semiconductor fabrication environments.

Usage & Installation
- Mounting: Use the integrated chassis mount slide bracket to position the detector. Ensure the 120° field of view covers the high-risk “fire threat” areas, such as wet bench working surfaces or chemical plenums.
- Wiring: The unit comes with a standard 20-foot pigtail cable. Connect the black (24V Return) and red (+24V DC) wires to a regulated power source. Connect the relay wires (Brown/Blue for Alarm, Yellow/Orange for Alert) to your fire alarm panel.
- Communication: For digital diagnostics, use the RS-485 interface to retrieve FirePic™ data (time-stamped digital fire signatures) and event logs.
- Maintenance: The device features a built-in automatic self-test. Periodically wipe the window lens with a clean, soft cloth and mild detergent to ensure optical clarity.
Key Application Fields
- Semiconductor Manufacturing: Wet bench working surfaces and subsurfaces (plenums).
- Clean Rooms: Open area monitoring where combustible materials are processed.
- Chemical Processing: IPA (Isopropyl Alcohol) stations and chemical etch areas.
- Industrial Automation: High-speed detection for pumps and equipment located behind clean room walls.
