It provides versatile control features for commercial and light industrial applications in non-hazardous and non-explosive environments. The FCS is designed to receive inputs from digital and\/or analog transmitters and\/or peripherals (in various combinations) via Modbus\u00ae RTU RS-485 or a 4-20 mA analog input.<\/p>\n<p>The FCS is available in 4, 8, 32, and 128-channel versions, with Modbus\u00ae RTU RS-485 or BACnet\u00ae MS\/TP RS-485 WAN outputs for communication with a building management system (BMS).<\/p>\n<p>All models include four internal dry-contact SPDT relays with field-configurable tripping times and thresholds, a color resistive LCD touchscreen with an LED panel displaying channel alarm status, relay status, and faults, an intuitive password-protected menu system, enhanced control logic, prioritization\/zoning functions, a USB port for firmware updates and data logging, and an integrated door audible alarm. The FCS offers flexible configuration for analog outputs and supports 4-20 mA variable frequency drives and Modbus\u00ae.<\/p>\n<p>Value-added options include analog inputs and\/or outputs, an integrated strobe light, a lockable door, a manual override switch, and an integrated weatherproof door audible alarm.<\/p>\n<h4>Features, Options, and Instructions for Remote Devices<\/h4>\n<p>FCS-M models offer a Modbus\u00ae RTU RS-485 digital output signal for LAN and WAN communications.<br \/>\nFCS-B models offer a BACnet\u00ae MS\/TP RS-485 output signal for WAN communications (for communication with a building management system).<\/p>\n<ul>\n<li>Graphic color touchscreen LCD with LED indicators<\/li>\n<li>Intuitive menu system with password protection<\/li>\n<li>Optional internal analog inputs and\/or outputs with flexible configuration parameters<\/li>\n<li>Enhanced logic control, zoning, and priority structure capabilities<\/li>\n<li>Compatible with 4-20 mA variable frequency drives and Modbus\u00ae<\/li>\n<li>4 internal dry contact relays, 5 A at 240 V each (up to 64 total)<\/li>\n<li>with remote relay modules)<\/li>\n<li>2 dedicated outputs for buzzer\/strobe, 0.5 A at 24 V DC max<\/li>\n<li>Mains voltage (90 - 240 V AC)<\/li>\n<li>USB port for firmware updates and data logging<\/li>\n<li>Configurable to meet California Title 24 Energy Efficiency Standards<\/li>\n<li>Door buzzer, optional waterproof version<\/li>\n<li>Standard waterproof and dustproof enclosure, corrosion resistant (splashproof); IP54 protection rating with installed weatherproof door audible alarm<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h4>The FCS system can be connected to the following CET remote devices:<\/h4>\n<ul>\n<li>Remote buzzers\/strobes<\/li>\n<li>Remote display module (CET-RDM)<\/li>\n<li>Remote relay module (RLY-4 and\/or RLY-8)<\/li>\n<li>LNK-AI analog input device<\/li>\n<li>LNK-AO analog output device<\/li>\n<li>LNK-XT network extension<\/li>\n<li>Remote power supply (RPS-24VDC)<\/li>\n<\/ul>\n<h4>Datasheets for other models and brochure<\/h4>\n<p class=\"link-btn-style btn-blue\"><a href=\"https:\/\/chevrierinstruments.com\/wp-content\/uploads\/2026\/07\/CETCI-FCS-4-general-brochure.pdf\" target=\"_blank\" rel=\"noopener\">FCS-4 general brochure<\/a><\/p>\n<p class=\"link-btn-style btn-blue\"><a href=\"https:\/\/chevrierinstruments.com\/wp-content\/uploads\/2026\/07\/DS-CETCI-fcs-8.pdf\" target=\"_blank\" rel=\"noopener\">FCS-8 data sheet (English)<\/a><\/p>\n<p class=\"link-btn-style btn-blue\"><a href=\"https:\/\/chevrierinstruments.com\/wp-content\/uploads\/2026\/07\/DS-CETCI-fcs-32.pdf\" target=\"_blank\" rel=\"noopener\">Technical sheet FCS-32 (English)<\/a><\/p>\n<p class=\"link-btn-style btn-blue\"><a href=\"https:\/\/chevrierinstruments.com\/wp-content\/uploads\/2026\/07\/DS-CETCI-fcs.pdf\" target=\"_blank\" rel=\"noopener\">FCS-128 data sheet (English)<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<h2>FCS<\/h2>\n<p>High-performance controller with logic and priority parameters for monitoring toxic, combustible, and refrigerant gases, offering great versatility.
