                        Early Warning, Early Success
                        Smoke is fire’s greatest weakness, because it provides us an early warning of the threat of fire. If we can detect smoke quickly enough and take advantage of that tell-tale sign, we can gain a real edge in our fight against fire. That is the reason why virtually every large establishment in the world places smoke detection systems high on their list of priorities. As the fire detector picks up smoke signals and sends out an early alarm, the time window we get can save precious lives and expensive premises. For, as we all know, without early warning, the fight against fire is all but lost.
