What is a NAC Power Supply?
NAC is an acronym which stands for “Notification Appliance Circuit”. So, there are essentially three parts to this particular product.
Notification: This means that the NAC Power Supply provides the notifications to the occupants. These notifications can be of fire or any other emergency which could prove to be fatal.
Appliance: The NAC Power Supply uses several different appliances to sound the notification and alert the occupants. These appliances include, but are not limited to horns, strobes, alarms, chimes, bells, klaxons and so on.
Circuit: A circuit simply means a closed loop of electrical devices and a power source. The circuit connects the power source of the building or residence to the notification appliances such as horns and strobes.
NAC Power Supply systems have been functioning in buildings and residences ever since the advent of safety standards in the industries. NAC Power Supply systems provide a sure-fire way to provide emergency notifications to the occupants of a particular building or residence.
The NAC circuit is designed to start at the main fire alarm panel and connects to the notification devices in the building or residence, thereby completing the circuit. The NAC circuit is usually a simple circuit which is designed by our expert engineers. This circuit is usually a two-wire circuit and makes use of an end-of-line resistor to end the circuit.
The NAC Power Supply system’s provided by NY Engineers works in two major modes: The Supervision mode and the Alarm mode. The Supervision or the Standby mode means that the NAC Power Supply will stabilize the power provided to all the appliances in the circuit without overworking the circuit or using too much power.
The Supervision mode is useful when you know you’re not doing critical work and there are lesser chances for an emergency situation. While the Alarm Mode is useful when you’re sure that there are more chances for there to be emergency situations such as a fire. The Alarm mode is usually used in places like mechanical rooms and testing rooms where the equipment is more likely to catch fire.
NY Engineers provide the NAC Power Supply with a simple switch which is basically a relay. This switch allows you to switch between the two modes for either convenience or for need. This is a physical switch that lies on the control panel of the NAC.
