The Xtralis VSP-036 is the replacement ultrasonic flow sensor manifold for the VESDA LaserINDUSTRIAL (VLI) aspirating smoke detector. In the VLI, the air sample passes four sets of ultrasonic flow sensors at the detector inlets before reaching the Intelligent Filter, allowing the detector to monitor airflow in each pipe.
Key features
- Genuine Xtralis field-replaceable spare for the VLI
- Houses the ultrasonic flow sensing used for the VLI's airflow monitoring on its four inlet pipes
- The inlet flow readings are also compared with the Intelligent Filter's unfiltered path to measure filter loading
- Modular design for ease of servicing
Technical specifications
- Part number: VSP-036 (VLI Ultrasonic Flow Manifold Spare)
- Compatible detectors: VESDA VLI-880 and VLI-885
- VLI inlets: up to 4 pipes, 25 mm (1") external diameter
- VLI minimum airflow: 40 l/min total, 20 l/min per pipe
