Description
The Safe Signal Sprinkler EPS10-2 2-SPDT Alarm Pressure Switch is designed to monitor pressure variations and activate electrical signals when levels change within the 4–20 PSI range. In HVAC systems integrated with fire protection and sprinkler networks, it is used to sense pressure fluctuations in piping lines and initiate alarm circuits through its dual SPDT contact arrangement, enabling multiple control outputs from a single sensing unit. An internal diaphragm responds to pressure movement and converts it mechanical switching action. It is installed on pipeline sections, supporting accurate pressure supervision and steady circuit response during system monitoring cycles.
