TEST & MONITORING EQUIPMENT SBS-C4H10 Butane / Isobutane Gas Detector Complete Butane / Isobutane Detection System The SBS-C4H10 Butane / Isobutane Detector is a butane / isobutane detection system with visual and audible alarms and 25%LEL and 50%LEL butane relays. The system comes complete with the main control, a highly accurate butane / isobutane gas sensor and a 25 ft. cable. This unit can be powered with AC and/or DC power and can be mounted directly to a wall or to an electrical box, making it extremely versatile and very user-friendly. The SBS-C4H10 includes relays for remote connection to alarm/monitoring systems and for control of external relays or an exhaust fan. Benefits • Protects life, property and company profits • Ideal for remote locations • Fail safe mode in event of loss of power • Up to three (3) sensors can be installed to main control to meet space coverage requirements BUTANE / ISOBUTANE GAS DETECTOR Includes • Main control • Butane / Isobutane sensor Features • Universal power inputs: 110/220 Vac and/or 12-48 Vdc input • 25 ft. cable • Strobe light for visual alerts • Sensor status indicator LEDs on the main control • Modular design for optimal placement of sensor(s) Applications • Oil, gas and refinery • Chemical plants Installation • Rubber and plastic manufacturing • Wall or 2-gang junction box mountable • LpG production facilities • Mechanical relays are easily accessible: • Refrigerant applications • Warning 25% relay, 15 A @ 120 Vac; 10 A @ 277 Vac; 10 A @ 28 Vdc • Butane / |sobutane fueled back- • Alarm 50% relay, 0.5 A resistive @ 28 Vdc, 0.5 A @ 125 Vac up power systems • Redundant power supply capability; dual AC and/or DC power supply connections (DC power supply will operate as backup power source) • Indicator LEDs can be tested by pushing the red “TEST” button • Sensors can be tested in the field with the P/N C4H10-TESTKIT Main Control Mounting and Power Options

Alarm Settings: Should the butane / isobutane 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).
