Aspiration System – VESDA
An aspiration detection system is a highly sensitive form of fire detection that can detect a fire at an early stage. The system takes samples of the air and tests them for the presence of smoke.
Benefits :-
- Provides an early warning of smoke before it is even visible to the human eye
- An ASD works even when the air handling system is not working
- Works well even in low air damper environments
- Easy accessibility for service and testing remote areas such as lofty
ceilings without climbing ladders to maintain smoke detectors - ASD systems are compatible with addressable and conventional
fire alarm systems
”ASD System is required to meet NFPA codes and regulations, including NFPA 72, the National Fire Alarm and Signaling Code. NFPA 72 requires the sampling holes to be spaced at equivalent configurations of spot smoke detectors, which are spaced at 30 feet with the ability to protect 900 square feet. Requirements for a Standard Fire Detection (SFD) system require maximum transport time of the furthest sampling hole to the ASD be no more than 120 seconds”.
