Description

Key Technical Specifications

FS7-2173-2RP FSC

Product Introduction

The FSC FS7-2173-2RP is an advanced multi-spectrum flame detector designed for high-reliability fire safety in industrial environments. It utilizes digital electro-optical technology to analyze multiple spectrums of radiation (Infrared and Visible light), allowing it to distinguish between actual flames and false alarm sources like heat lamps, welding, or sunlight. This makes it ideal for complex environments such as semiconductor cleanrooms, wet benches, and chemical processing areas.This detector features a “two-stage” response capability, differentiating between a warning condition (small fire, ~3kW) and a full alarm condition (large fire, ~13kW). It connects via an RS-485 digital interface, allowing multiple units to be daisy-chained to a central controller (such as the FS7-130-SX). The unit is built with a rugged, sealed polypropylene housing that resists acids and harsh chemicals, ensuring durability in corrosive atmospheres.

Installation & Configuration Guide

Preparation (10 min)

1. Safety: Ensure the control panel power is OFF.
2. Verify the detector model matches the controller compatibility list (FS7 Series).
3. Plan the mounting location to ensure a clear 120° field of view of the hazard.

Removal (5–10 min)

1. If replacing an old unit, disconnect the 20-foot tail cable from the junction box or controller.
2. Unscrew the mounting bracket.

Installation (10 min)

1. Secure the sliding mount bracket to the wall or equipment surface.
2. Connect the detector’s 20-foot cable to the RS-485 FireBus interface (check polarity).
3. Slide the detector onto the mount and adjust the angle to cover the protected zone.
4. Tighten the bracket to lock the position.

Power-On & Test (10 min)

1. Restore power to the FS7 controller.
2. The detector will perform an automatic self-test (approx. 10-second cycle).
3. Use the controller interface or PC software to verify the “FirePics™” history and ensure the unit is communicating on the bus.
4. Perform a functional test using a calibrated light source if available.

Troubleshooting Quick Reference

Dimensions, Mounting & Wiring Notes

• Dimensions: Compact, streamlined housing (verify exact HxWxD from physical label, typically approx. 150mm x 100mm x 80mm).
• Mounting: Sliding mount bracket allows for easy angle adjustment.
• Wiring: 20-foot (approx. 6m) pre-terminated tail cable with locking connector.
• Connection: RS-485 2-wire interface (plus power/ground).
• Note: The housing is IP67 rated, making it suitable for washdown areas or outdoor use (with proper cable gland sealing).

FAQ

What is the difference between the FS7-2173 and the 2RP model?
The “2RP” designation typically refers to the specific revision or packaging (e.g., 2-wire/RS-485 configuration with polypropylene housing). Ensure it matches your controller’s compatibility list.Can this detector work with sunlight or heat lamps nearby?
Yes, the FS7-2173-2RP uses multi-spectrum analysis to reject false alarms from background radiation, heat lamps, and welding, provided they are not directly in the immediate focal path.What controller do I need for this detector?
It is designed to work with FSC controllers like the FS7-130-SX or the FSWB control board, which provide power and process the RS-485 signals.How far can I run the cable?
Since it uses RS-485 digital communication, you can typically run long cable distances (up to 1200 meters) depending on the gauge and environmental noise, though the unit comes with a standard 20-foot tail.Does it store alarm history?
Yes, the detector has non-volatile memory that stores up to 6 “FirePics™” (flame data snapshots) and 200 events with timestamps, retrievable via the controller.
