SBS-H2-DoD HYDROGEN GAS DETECTOR
Hydrogen 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)
- NRTL/C Certified: UL Std. No 61010-1 & CAN/CSA-C22.2 No. 61010-1-12
- UFC 3-520-05, January 2020
Installation
- Wall or 2-gang junction box mountable
-
Mechanical relays are easily accessible:
- Warning 0.5 % relay, 15 A @ 120 Vac; 10 A @ 277 Vac; 10 A @ 28 Vdc
- Alarm 1% 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 H2-TESTKIT
Detector can operate exhaust fans and building alarms / SCADA systems:
Warning Settings: Should the concentration of hydrogen gas in the air surrounding the sensor reach 0.5% by volume, the “0.5% Warning” yellow LED will light up on the main control of the unit. In addition, the 0.5% internal relay will energize and can be used to activate an external exhaust fan or a building management/alarm system (via SCADA Modbus).
Alarm Settings: Should the hydrogen gas concentration reach 1% by volume, the “1% Alarm” red LED will light up, the strobe will flash and an audible alarm will sound. In addition, the 1% internal relay will energize and can be used to activate a building management/alarm system (via SCADA/Modbus).
