Central Amplified Speaker Notification Appliance Output Wiring
The audio alarm current of the amplifier module depends on the number of speakers on the circuit, length
and gauge of wire of the audio circuit, and the audio mode in use.
When laying out each NAC circuit for the speakers, calculate the total wattage required. A good
engineering practice is to not exceed 85% of the amplifier rating that you plan to use. If your calculations
exceed this, an amplifier having increased power capacity is required or replacing the entire SAFEPATH
®
Panel with greater capacity.
Wire gauge may vary for each audio appliance output on the panel. When:
• Speaker (with transformer) appliances are used with supervised audio amplifier module
(central amplified outputs). Wire gauge selection should involve consideration of all
factors including, wire length, appliance power ratings, and the number of appliances.
