VFT-15 15 Tube Addressable Air Sampling Detector

VESDA VFT-15 detectors are multi-channel microbore air-sampling systems with an alarm sensitivity range from 0.001% to 20% obscuration/m (0.0003% to 6.10% obscuration/ft).

These detectors are classified as Very Early Warning Smoke Detectors and can reliably detect fire at an early stage, and low to high concentrations of smoke.  As a multi-channel system, the VFT detector is able to divide a protected space into sampling sectors, enabling the localization of a fire for faster incident response.

Features:

• 15 tube addressable air sampling
• 0.001% to 20% obscuration/m (0.0003% to 6.10% obscuration/ft)
• 4 Alarms - Alert, Action, Fire 1, Fire 2
• 15 x 50m (15 x 164ft) microbore sampling tube
• Reliable linear pump technology
• Ethernet TCP/IP
• RS232 and RS485 Modbus
• 5 relay outputs and expandable
• Optional relay module and 4 to 20 mA analogue output modules
• Area coverage of up to 1500 m² (16 150 ft²)
• Event Log

How It Works

The VESDA VFT detector is a 15 channel microbore air sampling system with the ability to identify the location of an incident within a large area split into 15 sectors. Air is drawn from the protected area through this network of microbore flexible tubing (6 mm or 0.25 in). In the event that smoke particles are detected a TRACE alarm will be raised and the system will identify the sector, or sectors, with the smoke condition.

The Unique Features of VESDA VFT

• 6 mm (0.25 in) microbore air sampling
• 15 x 50 m (164 ft) microbore sampling pipe
• High sensitivity - 0.001%% to 20% obs/m (0.0003% to 6.1% obs/ft)
• 4 Alarms - Alert, Action, Fire 1, Fire 2
• Powerful suction rotary vane vacuum pump – 0.7 Bar with sensitive airflow monitor
• Large, clear display panel

Typical Applications

The VESDA VFT range is ideally suited for a wide range of applications including:

• computer and server rooms, where a specific enclosed server cabinet can be identified and singled out for investigation
• switchgear cabinets, clean rooms and research facilities
• prison and correctional institutions for compartmentalized, tamper-proof smoke detection
• exclusive homes, apartments, hotels, shops and office blocks where high performance but discrete smoke detection is required.
• ancillary high risk area protection in pharmaceutical and clean rooms.
