Connecting Notification Appliances
Connection of notification appliances in a Class
A configuration.
Connection of notification appliances in a Class
B configuration.
Do not insert more than one conductor per terminal. Use wire nuts or other suitable splice connectors to connect
the end-of-line diode and Class Aloop return wire. Cable gauge must be sized according to length and device
load to ensure that voltage-drop of the cable does not result in less than the minimum operating voltage of the
notification appliances. Different limitations will apply for devices with a higher or lower minimum working
voltage. Refer to Specifications for cabling information.
To install notification appliances on the Aura Fire Alarm ControlPanel:
1. Connect notification appliances and End-Of-Line diodes to the NAC output.
2. Connect End-Of-Line diodes to unused NAC outputs.
3. Maintain the limit for maximum wire length of the circuit.
Notification appliances connected to NAC outputs on a single panel are synchronized. Notification appliances
connected to SLCloops on a single panel are synchronized. However, notification appliances on separate
panels are not synchronized. Per NFPA72,
Audible Devices
The installation of one group of synchronized-audible notification appliances shall not be installed in
hearing range of another group of synchronized-audible NACs.
Visual Devices
The installation of one group of synchronized-visual notification appliances shall not be installed in
line-of-sight of another group of synchronized-visual notification appliances.
Refer to Equipment List for synchronization devices that are UL listed and authorized for use with the Aura Fire
Alarm ControlPanel. Refer to Calculations to determine wire size requirements for your application.
