Aspirating Smoke Detection (ASD)

VESDA System

Early warning of an imminent fire condition by employing a Very Early Smoke Detection Apparatus (VESDA) may provide sufficient early warning that prompt investigation, action and control can be implemented prior to serious damage.

VESDA systems are an early warning of an incipient fire condition and therefore a precursor to and of higher sensitivity than a conventional smoke detector, therefore not required at that stage of sensitivity to be linked to the main building fire alarm system.

Early action may avoid the general fire alarm in a building activating – how much time and cost is lost through persons standing out on the street whilst the fire alarm is investigated and persons allowed to re-enter the building to continue their work? It can avoid possible shutdown of air con controlling the Server Room with possible overheat and loss of server function.

Avoids probable escalation to a gas release – a VESDA system would be less than the recharge costs of any gas suppression system.
