VESDA XCL-LB-CO2VV-RA Large Bore CO2 Gas Detector (5% v/v, 4-20mA)

The Xtralis VESDA Sensepoint XCL Large Bore (XCL-LB-CO2VV-RA) is an aspirated carbon dioxide (CO2) gas detector that fits in-line in a standard aspirating smoke detection (ASD) pipe network, with 4-20 mA analogue 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

• Carbon dioxide (CO2) sensor, 1.0-5.0% v/v
• 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, calibration and maintenance
• 4-20 mA output plus 2 configurable relays for integration with BMS, fire panels, PLCs and HVAC
