The Consilium ANALOGUE M4-20, part number 5110003-20A, is a specialized analogue addressable input unit designed for seamless integration with Salwico fire detection systems. Its primary function is to monitor external equipment that provides a standard 4-20 mA output signal, such as gas detectors, pressure sensors, temperature sensors, or level sensors. This unit effectively translates the analogue signal from the external device into data that can be interpreted by the fire alarm control panel, allowing for comprehensive system monitoring and the triggering of alarms or pre-alarms based on configurable thresholds. Housed in a durable enclosure, the M4-20 is engineered for reliability in demanding environments, particularly within marine and offshore applications, ensuring critical system components are continuously supervised.
