SBS-CH4 METHANE GAS DETECTOR

Methane Sensor and Monitoring System

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

Features

• Universal power inputs: 110/220 Vac and/or 12–48 Vdc input
• Strobe light for visual alerts
• Sensor status indicator LEDs on the main control
• Modular design for optimal placement of sensor(s)

Installation

• Wall or 2-gang junction box mountable
• Mechanical relays are easily accessible:
  • Warning 25% relay, 15 A @ 120 Vac; 10 A @ 277 Vac; 10 A @ 28 Vdc
  • Alarm 50% relay, 0.5 A resistive @ 28 Vdc, 0.5 A @ 125 Vac
• 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 CH4-TESTKIT

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

Warning Settings: Should the concentration of methane 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 methane 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).
