A NAC (Notification Appliance Circuit) extender is a device used in fire alarm systems to expand the capacity of the notification appliance circuit. NACs are used to power and control fire alarm notification devices such as strobe lights, horns, and speakers. When the capacity of a NAC is limited or when additional devices need to be added to the circuit, a NAC extender is employed to increase the number of devices that can be connected. This cost-effective solution allows for greater flexibility in the design and implementation of fire alarm notification systems, ensuring effective and widespread alerting during fire emergencies.
