S-2A Propane / CNG Monitor and Control
The S-2A propane monitor / controller features include low current draw, plug-in sensors (second sensor optional), display module fault light / alarm and fault light / alarm to indicate a malfunction in either one of the sensors. (Fault indicators show that the module or sensors are not working and may need repair.)
MS-2 sensor and 1 SV-1 solenoid valve included.
The system is calibrated at 20% LEL (lower explosive limit) to eliminate most nuisance alarms while allowing enough time to take action.
A microprocessor-controlled two-channel monitor with automatic solenoid valve on / off switch
A "press to test" button for each channel confirms function
