Prepare System Wiring Diagram
Prepare a system-wiring diagram to include all Notification Appliances, and internal connections and
power sources as required.
NOTE: Separate input power wiring from the other input and output wiring. Wire the input
power to the left side of the motherboard (Figure 3-16, Page 3-21) and the other input and
output wiring to the right.
Visual Notification Appliance Output Wiring
● Wire gauge selection involves consideration of all factors including, wire loop length, maximum
current draw of each appliance, number of appliances, and maximum voltage drop allowable.
● Strobe NAC has a 24VDC, 2.0 amps maximum output.
● Strobe NAC meets Class B supervision requirements for notification appliance circuits.
● The strobe output circuit shall have a UL Listed 10K Ohm, ½ W EOLR installed across the last
visual notification appliance. If the output is unused, a UL Listed 10K Ohm, ½ W EOLR shall be
placed across the output terminals.
Speaker Notification Appliance Output Wiring
Wire gauge may vary for each audio appliance output on the panel. When:
● Speaker (with transformer) appliances are used with supervised audio amplifier module. Wire
gauge selection should involve consideration of all factors including, wire length, appliance power
ratings, and the number of appliances.
● The amplified output is either a selectable 25 or 70.7Vrms audio output, rated for 40 watts
maximum.
● The output meets Class B supervision requirements for notification appliance circuits.
● The audio output circuit shall have a UL Listed 10K Ohm, ½ W EOLR installed across the last
notification appliance. If the output is unused, it shall have a UL Listed 10K Ohm, ½ W EOLR
across the output terminals.
