Public Vs. Private Mode of Signaling : Our team of engineers, experts and, professionals will first survey your residence or building to figure out what kind of systems are in place. The engineers will figure out the exact parameters and factors that make up the system. Once this is done, the team will prepare a comprehensive document that will enlist all the systems, their working and their wiring in the building.
This is necessary for them to do for several reasons, but one major reason is to figure out which kind of signaling is going to be needed. NFPA allows for two kinds of signaling: public signaling and private signaling. This will depend on how the area is used or has been used, what the occupancy rate is, and several other factors as well.
NY Engineers will provide both modes of signaling depending on the area, the kind of people covering that area and other factors.
Public-Mode Signaling : Public-Mode signaling is a popular and common way of signaling. This kind of signaling informs all the occupants of the notification or the emergency. This is usually used in places where people are capable of self-evaluation. Many people occupying a building are mentally and physically capable of evacuating the building themselves which is why this method of signaling is most common.
Public-mode signaling offers a way for the general public to react independently and allow the occupants to evacuate the building on their own.
Private-Mode Signaling : In private-mode signaling, all the occupants of the particular area are not informed of the emergency notification. This is done when the management is unsure whether the people occupying a particular area are capable of reacting and acting independently. If the management deems them unfit, then private-mode signaling is used.
What this does is that it only informs the people concerned in the emergency department about the emergency notification but does not tell the general public about it. So, this way the concerned officials make it their responsibility to evacuate everyone out of the building in a safe and secure way without causing panic or harm.
This kind of emergency signaling is used in places where there is more general public than staff. This includes places like detention centers, hospitals or other healthcare facilities and also facilities for special children or people.
Private-mode signaling should be given top priority when the total occupant coverage by the emergency notification would not act in benefit of the occupants. There have been many cases in the past that have shown that it can be harmful and otherwise dangerous for individuals occupying a particular building to evacuate on their own.
