Xtralis VESDA VFT-15Sales and TechnicalSales and Technical Presentation

Extending the VESDA Range

The Xtralis VESDA VFT-15 is a unique and versatile high sensitivity ASD that can pinpoint the source of an incipient smoke incident

– Minimises business disruption and downtime

– Speeds response

– Enhances investigation

Two variants are available

– VFT-15 (0.01 – 20% Obs/m or 0.003 – 6.10% Obs/ft)

– VFT-15-C(1 – 20% Obs/m or 0.3 – 6.10% Obs/ft)

VESDA VFT-15 Value Proposition

The only ASD product available on today’s market to provide:

Pinpoint location of the source and location of an incipient smoke incident, therefore minimising investigation and downtime

Intelligent addressability to identify up 15 protected areas respectively via microbore air sampling tubesrespectively, via microbore air sampling tubes

High sensitivity ranging from 0.01 to 20 % obs/m (0.003 –6.10% obs/ft)

Optional CO gas sensor

The VFT-15 is complementary to the existing range and provides pinpoint addressability at a more compelling price than multiple VLS units with single hole pipes.

Site conditions and pipe network design will determine the final choice of detector.

Principle of Operation

Actively draws air from the protected area through a network of flexible pipes

Filters and conditions the air where necessary

Analyses the air for low levels of smoke

Id tifi th i hi h th Identifies the pipe on which the incident occurred

Sets alarms on four programmable thresholds

Reports the alarm via relay outputs or communication network

Detection Principle VFT

Sensitivity from 0.01% - 20% obs/m (0.003 – 6.10% obs/ft) for VFT-15 or 1% -20% obs/m (0.3 – 6.10% obs/ft) for VFT-15-C

Sampling Components

Powerful 0.7 Bar suction rotary vane vacuum pump.

15 way rotary valve incorporating pressure sensor.– Trace mode of operation: samples overall from all pipes

• 30 sec to detection

– Selection mode: Scans sectors when smoke detected

• +/ 9 sec/pipe• +/- 9 sec/pipe

– Self test mode: every 20 min

• 1/1 dilution (no dilution of smoke sample)

VFT-15 Microbore Sampling

The VFT-15 requires microbore, which is 6 mm OD and 4mm ID flexible nylon tube.

All lengths should be equal with a maximum allowable length of 50 m per tube.

Other materials may be used such as Stainless Steel with suitable adaptors for harsh environments.

Never glue to the inlets of the detector.

Unused inputs should be looped to one another using short lengths of microbore.

Typical VFT-15 Applications

Electronic data processing equipment

High sensitivity

Micro bore pipes forMicro bore pipes for individual cabinet identification

Unaffected by high air speeds

Optional integral hydrogen monitoring of UPS rooms

A highly addressable solution for fully-enclosed cabinets

Extending the VLP-VLS solution

Typically a VLP would be used to protect the open environment of the modern high density data centre.

Addressability to a particular area might be possible by using a VLS pipe per isle or per grille but this can be economically challenging

Extending the VLP/VLS solution

The application of VFT-15 provides fully addressable coverage of the mission critical cabinets while the VLP detects less critical environments such as across the return air grille and hot isles.

Typical VFT-15 Applications

Mines and Electrical Substations

Operates in dusty environments

Individual protection of high-voltage switchgear cabinetsvoltage switchgear cabinets

HV cabinets are bolted and cannot be opened easily

PLC and control rooms

Electrical substations

Extending the VLP-VLS solution

The current solution for protecting low heat load vented cabinets is to sample at the top of the cabinet using capillary tubes placed into the various cabinets from a main branch pipe.

The disadvantage is that only aThe disadvantage is that only a global alarm will be generated, requiring visual inspection of each cabinet to determine the source

Use of a VLS provides enhanced addressability per main branch pipe but still does not provide individual cabinet identification

Extending the VLP-VLS solution

The VFT-15 offers an extremely competitive and more elegant solution for identifying up to 15 individual cabinets.
