VESDA XCL-LB-H2-RM Large Bore Hydrogen Gas Detector (1,000ppm, Modbus)

The Xtralis VESDA Sensepoint XCL Large Bore (XCL-LB-H2-RM) is an aspirated hydrogen (H2) gas detector that fits in-line in a standard aspirating smoke detection (ASD) pipe network, with Modbus RTU output and relays. It uses the airflow in the pipe to deliver multi-point gas sampling, giving gas detection for occupant protection and process monitoring alongside fire protection.

Key features

• Hydrogen (H2) sensor, 1000 ppm (fixed)
• Modbus RTU output plus 2 configurable relays (alarm, fault)
• Multi-point aspirated sampling through the ASD pipe network for greater coverage than a fixed point detector
• Remote sampling: the detector can sit outside the protected zone for safe, convenient servicing
• Integral alarm status LEDs and gas port for bump testing and calibration
• Field-replaceable gas sensor cartridge
• Bluetooth pairing with the Sensepoint app for commissioning and maintenance
• Modbus version can be monitored in Xtralis VSC and VSM4, and networked to the Sensepoint 301C gas controller for extra relays
