How Does VESDA Work?

A detection

system that

actively draws air

from a fire zone

to a centrallymounted detector

VESDA Sampling Detection principles

NFPA 72, the max spacing for sampling holes is 30 ft centers


12/97

Active vs. Passive Detection

VESDA: ActiveDetection Non reliant on air currentsfor smoke delivery

Functions effectively in wide range of environments

from high airflow to still air

Passivespot and beam type

detectors rely on thermal lift

to deliver smoke to detection

VESDA ECO Gas Detector


57/97

VESDA ECO Positioning

VESDA ECO adds gas detection capability to existing or

new installations of VESDA smoke detection systems.

VESDA ECO can detect a range of flammable, toxic and

oxygen gas hazards.

VESDA ECO can provide a greater area of coverage than

fixed point gas detection systems.

VESDA ECO is for indoor non Hazardous classified areas

only.

VESDA ECO is not intended to be a stand alone gas

detection system.


58/97

A Cautionary Note

To ensure correct application of VESDA ECO, only fully

trained and accredited distributors / installers will be

permitted to sell VSDA ECO

VESDA ECO is for use exclusively with compatible

Xtralis manufactured ASD.

VESDA ECO has been third-party validated, ensuringXtralis ASD smoke performance is not compromised.

VESDA ECO is not approved or warranted for use on

other (non Xtralis) ASD products.

No other third party gas detector is approved for use with

Xtralis ASD and would void the Xtralis ASD warranty.


59/97

Features (Detectable Gases)

VESDA ECO detectors have a sensor cartridge containing 1 or 2 gas sensors.

VESDA ECO uses industry proven electrochemical & catalytic sensors.

Additional gases will be added to the range. All new requests welcomed.

Recommended to replace every 2 years

Filter Technology


76/97

gy

dust particles are counted as they pass through the

detector chamber.

You can enter a predetermine time stamp i.e.. 730

days (2 years) and at the end of that time a filterwarning is given to re-visit the detector to determine if

a new filter needs to be inserted.

Replace filters every 24 months, or as needed for

challenging environments. When the filter is removed from the VLP, the aspirator

shuts off, the buzzer sounds (if enabled) and an

urgent fault is raised.
