Amplified Speaker Notification Appliance Power Output Wiring
Up to four amplified speaker notification appliance power outputs may be provided. Each output is rated for 24VDC, 2.0 amps
maximum. Each output meets Class B, Style Y supervision requirements for notification appliance circuits. The wiring diagram for
the amplified speaker notification appliance power output using audio only appliances is shown in Figure 17. The wiring diagram for
the amplified speaker notification appliance power output using combination audio/visual appliances is shown in Figure 19.
Each output circuit must have a LISTED 10K end-of-line resistor installed across the last appliance. All unused outputs must have a
LISTED 10K end-of-line resistor across the output terminals. The LISTED 10K end-of-line resistors must have a 1W minimum
power rating and a 5% maximum tolerance
The gauge of the wire necessary for the wiring may vary for each amplified speaker notification appliance power output on the
SAFEPATH panel. Determination of wire gauge should consider all factors including wire loop length, the maximum current draw of
each appliance, the number of appliances, and the maximum voltage drop allowable.
Remote Microphone Station (RMS-1) Wiring
Use twisted shielded wiring between the remote microphone station and the SAFEPATH panel. Connect shield to the panel ground
connection only. The maximum distance between the RMS-1 and the SAFEPATH panel is 1000 Ft. with a minimum wire size of 22
AWG, with a maximum capacitance of 50pF/Ft. or .05uF/Total run. The wiring diagram for the remote microphone station is shown
in Figure 20.
