Detector can operate exhaust fans and building alarms / SCADA systems:

Warning Settings: Should the concentration of propane gas in the air surrounding the sensor reach 25%LEL by volume, the “25%LEL Warning” yellow LED will light up on the main control of the unit. In addition, the 25%LEL internal relay will energize and can be used to activate an external exhaust fan.

Alarm Settings: Should the propane gas concentration reach 50%LEL by volume, the “50% Alarm” red LED will light up, the strobe will flash and an audible alarm will sound. In addition, the 50%LEL internal relay will energize and can be used to activate a building management/alarm system (via SCADA/Modbus).
