FS24X

Product Description

The Model FS24X™ Detectors sense the WideBand IR™ radiant energy of blackbody particulate and molecular emissions generated by BOTH hydrocarbon and non hydrocarbon flames and fires. The WideBand IR spectral radiant energy wavelengths sensed by the Quad (4) sensors span from approximately 0.4 to 5.0 microns for the FS24X. The Model FS24X Multi-Spectrum Fire and Flame Detectors are designed and Factory Mutual approved for use in Class I, Div. 1 and 2, Class II and Class III; Class I, Zone 1 AEx d and Ex d IIC Hazardous Locations and ATEX Certified Ex db IIC (T4-T6) and Ex tb IIIC (T4-T6) Flameproof (Figure 1-1 & Figure 1-2).

The FS24X Detectors are available in copper-free Aluminum or 316 Stainless Steel enclosure. The FS24X Detector electro-optical electronics module (puck) is enclosed in a field-replaceable black, hard anodized aluminum puck that provides superior ruggedness, handling, ease of installation, and protection against EMI/RFI.

FS24X Detector Field Connectors

The field connections feature two (2) connector choices for the installer:

1. A removable ten (10) pin screw terminal connector (J2) for hard-wired relay applications.

2. A removable six (6) pin screw terminal connector (J1) for analog output or RS-485 Digital Communication applications.

The removable connectors provide quicker installation and allows the Detector enclosure to be installed prior to the Detector Module (puck).

User Field Selectable Configuration Switches

1. The eight (8) pin DIP switch (SW2) is used to select the Detector's Sensitivity and Relay Options.

2. The ten (10) pin DIP switch (SW1) is used for:

• Selecting a unique digital address (128 choices).

• Factory Use

3. The ten (10) position Rotary switch allows selection of the analog and digital communication protocol.
