4.4.4 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 two amplified outputs are either a selectable 25V or 70.7V audio output, rated for 80 watts
maximum. The SPB-80/4 has one audio output, the SPB-160 has two, and the SPB-320 has four.
For the SPB-320, both SPB-160 modules must be set up for the same voltage.
The output meets Class B supervision requirements for notification appliance circuits.
For the audio output circuit, install a UL Listed 10K Ohm, 1/2W EOLR installed across the last
notification appliance. If the output is unused, place a UL Listed 10K Ohm, 1/2W EOLR across
the output terminals.
