VESDA fire detection systems

Fire detection systems from Fire Tec provide unbeatable accuracy and ease of use for building, personnel, installers, and firefighters. At the first sign of danger, our reliable fire detection systems trigger a coordinated alarm, people are led out of the danger area via voice messages, and extinguishing systems are activated.

An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is classified as either automatically actuated, manually actuated, or both. Automatic fire alarm systems are intended to notify the building occupants to evacuate in the event of a fire or other emergency, report the event to an off-premises location in order to summon emergency services and to prepare the structure and associated systems to control the spread of fire and smoke.

Advantages Our fire detection and alarm systems offer reliable, early detection of all fire types coupled to superb false alarm management. They protect life, property and assist business by detecting fire at the earliest stage, allowing more time to evacuate, respond and extinguish fires before they become life, building or business critical.

• Protect your property, assets and people with monitored fire alarm systems

• Minimise false alarms

• Code regulated and approved systems

• Can integrate with other security alarm system

VESDA systems

VESDA works by continually drawing air into the pipe network via a high efficiency aspirator. A sample of this air is then passed through a dual stage filter. The first stage removes dust and dirt from the air sample before it allows the sample to enter the laser detection chamber for smoke detection. The second (ultra fine) stage provides an additional clean air supply to keep the detector’s optical surfaces free from contamination, ensuring stable calibration and long detector life. From the filter, the air sample is passed through to the calibrated detection chamber where it is exposed to a laser light source. When smoke is present, light is scattered within the detection chamber and is instantly identified by the highly sensitive receiver system.

The signal is then processed and presented via a bar graph display, alarm threshold indicators and/or graphic display. The VESDA detectors are able to communicate this information to a fire alarm control panel, a software management system or a building management system via relays or a High Level Interface (HLI).

The sooner your organization is alerted to a safety hazard or security breach, the more time you have to respond intelligently.
