By the time a fire is detected in a building it is often too late to do anything about it, but to evacuate. The secret to preventing a full blown disaster lies in VESDA smoke detectors which provide early warning of smoke. The pre-combustion stage is the best time to prevent a fire from spreading through a building. The second level is visible smoke and for this there should also be smoke detectors before the visible flames and uncontrollable heat phases set in. VESDA smoke detectors as available through IDTek can be set-up for early detection and alarming of smoke particles ensuring minimal loss of equipment, structure, and ultimately lives. The VESDA smoke detectors work well in office blocks, archives, power stations, museums and any area where conventional smoke detection systems often fail.
