1.0 Introduction 1.0 Introduction
The ENMET Model ISA-M detector/alarm is an all solid-state electronic gas-detecting instrument that minimizes the
risk of harm or death to people who are exposed to potentially hazardous gas environments. It continuously monitors
for combustible or toxic gases and warns of a dangerous gas situation with enough time to take action to avoid harm.
Audio (horn) and visual (light) alarms are calibrated to trigger at both high and low level gas concentrations.
The ISA-M uses a gas-sensitive Metallic Oxide Semiconductor (MOS) sensing element which reacts to toxic and
combustible gas molecules. An oxidation reaction occurs on the sensor surface when contaminants are present. The
oxidation reaction changes the sensor's electrical resistance which then triggers the alarm circuitry when the
concentration of gas goes beyond a preset level.
The sensor can be located up to 1000 feet from the circuit enclosure and connected electrically by wire or cable.
