FMC-2 and FMC-4 Two and Four Channel Fixed Systems Controller FMC-4 Four Channel Fixed Systems Controller The FMC-2 and FMC-4 controllers are designed to provide simultaneous display and alarm functions for two (FMC-2) or four (FMC-4) 4-20mA sensor transmitters. Easy to configure and user friendly, they can function as critical alarm controllers for toxic or combustible gases. The controllers are easy to install and feature a large graphical LCD display, standard 4-20mA inputs, and non-intrusive inputs for hazardous areas. Key Features • Multiple housing options for use in various environments • Authorization mode allows locking of critical configuration variables • Petrochemical industry • Internal power supply generates 24VDC and provides 15 watts total system power; optional 50-watt supply available • Flexible data input and output options • Accepts inputs from up to two (FMC-2) or four (FMC-4) 4-20mA sensors transmitters • Graphic LCD display provides clear presentation of sensor data and alert notification • Three independent alarm levels per channel. Relay Acknowledge feature allows silencing of external audible devices during existing alarm conditions • Chemical storage • LPG storage • Paint booths • Steel mills • Two standard SPDT common alarm relays are configurable for HORN, HIGH, WARN or FAULT • Touch and magnetic keypad for nonintrusive operation in potentially hazardous locations • NEMA 4X (Div. 2 certified) and explosionproof wall mount packaging options available Fixed gas detection systems are used to protect personnel and equipment
