Crowcon SMART 3-H-FM LITE | Flush-Mount Refrigerant and CO2 Detector | IR sensor, 2 relays, optional RS485
The SMART 3-H-FM LITE is a flush-mounted infrared detector from Crowcon's Sensitron line, made for refrigerant gases and carbon dioxide in commercial buildings where a discreet installation is wanted. Sensor options cover more than ten of the most common refrigerants, and the design follows the EN 378-3, EN 14624 and EN 50676 refrigeration standards. A side-mounted RGB LED shows status, and an internal buzzer sounds at alarm thresholds or on a fault.
