The S4S JB enclosure has been designed to allow quick and easy access to its interior by adjustment of four quarter turn screws, a major consideration when large system service and calibrations are being carried out.

The detector is robust and weather-proof to IP63 (IP65 with universal fitting) with improved response times. Standard 4-20mA and CANbus address enables the sensors to be networked via the Guardian Plus control system or customer preferred monitoring system.
