System Trouble Output Contact Wiring
One system trouble output contact is provided. It is Form C and is rated for 0.5 amps at 24VDC, resistive load. A detail of the
system trouble output contact terminal connections is shown in Figure 20. The contact in Figure 20 is shown in the trouble position.
Determination of wire gauge for the system trouble output contact wiring should consider all factors, including wire loop length,
maximum current capacity, and maximum voltage drop allowable.
Trouble Audible Output Wiring
One trouble audible output is provided. The output is rated for 24VDC, 0.1 amps maximum. The output is unsupervised. The
wiring diagram for the trouble audible output is shown in Figure 21. Determination of wire gauge for the trouble audible output wiring
should consider all factors, including wire loop length, maximum current capacity, and maximum voltage drop allowable.
Visual Notification Appliance Output Wiring
Up to four visual notification appliance outputs may be provided. Each output provided is rated for 24VDC, 2.0 amps maximum. All
four outputs combined may not exceed 6.0 amps maximum. Each output meets Class B, Style Y supervision requirements for
notification appliance circuits.
The wiring diagram for the visual notification appliance output using visual only appliances is shown in Figure 22. The wiring
diagram for a notification appliance output using combination audio/visual appliances in central amplified applications is shown in
Figure 25. The wiring diagram for a notification appliance output using combination audio/visual appliances in amplified speaker
applications is shown in Figure 26.
Each output circuit must have a LISTED 10K end-of-line resistor installed across the last visual notification 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 1/8W minimum power rating and a 5% maximum tolerance
The gauge of the wire necessary for the wiring may vary for each visual notification appliance 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.
Audio Notification Appliance Output Wiring
Up to four audio notification appliance outputs may be provided. Each output is either a central amplified output or an amplified
speaker output. Central amplified outputs are a 25V or 70.7V audio output, rated for 40W maximum. Amplified speaker outputs are
15 Ohm, -5dBm maximum. Each output meets Class B, Style Y supervision requirements for notification appliance circuits.
The wiring diagram for the audio notification appliance output using audio only appliances in central amplified applications is shown
in Figure 23. The wiring diagram for the audio notification appliance output using audio only appliances in amplified speaker
applications is shown in Figure 24. The wiring diagram for a notification appliance output using combination audio/visual appliances
in central amplified applications is shown in Figure 25. The wiring diagram for a notification appliance output using combination
audio/visual appliances in amplified speaker applications is shown in Figure 26.
Each output circuit must have a LISTED 10K end-of-line resistor installed across the last audio notification 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 audio notification appliance output on the SAFEPATH panel.
When speaker with transformer appliances are used (central amplified outputs), determination of wire gauge should consider all
factors including wire loop length, appliance power ratings, the number of appliances, and the maximum voltage drop allowable.
When amplified speaker appliances are used, determination of wire gauge should consider all factors including wire loop length,
output level, the output resistance, the input resistance of each appliance, the number of appliances, and the appliance input
sensitivity.
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 24. The wiring diagram for
the amplified speaker notification appliance power output using combination audio/visual appliances is shown in Figure 26.
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.
