VELOXASD-720 – Aspirating Smoke Aspirating Smoke Detector

Product Number: ASD-720


The VELOXASD-720 aspirating smoke detector is designed for areas up to 668 square metres (7,200 square feet). Total sample pipe runs up to 82.3 metres (270 feet) using 25mm (3/4” SCH-40) pipe to draw air samples from the protected hazard back to the detector for analysis.

Maximum number of sampling holes is 8 spaced no greater than 9 metres (30 feet) between sampling points. Spacing between sampling pipes must also not exceed 9 metres (30 foot) spacing.

Reset and Silence buttons, as well as LED indicators for Alarm, Fault and Power are used for operation and annunciation. Built in troubleshooting via the LED indicator.

The VELOX aspiration system utilize the state of the art image recognition detection. It allows the detector to identify the smoke particles, and provides accurate detection phenomena. Unlike other laser detectors, the VELOX ASD does not require any lens clearing or filters, and no extra commissioning is required. Once installed, and powered up, the system automatically shall adjust the pipes suction and pressure as per the UL requirements. The VELOX ASD shall be installed directly on the VELOX detection loop, and reports the address of each ASD back to the control panel, as well the VELOX ASD is having its own in-built isolator achieving reliable integration on the VELOX detection loop, hence the communication to the VELOX panels shall not be interrupted with a single short / open / earth fault.
