The Xtralis VESDA Sensepoint XCL Large Bore (XCL-LB-CH4-RA) is an aspirated flammable (catalytic) 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. For catalytic versions Xtralis specifies 10-90% RH operating humidity.
Key features
- Flammable (catalytic) sensor, 20-100% LEL
- 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
