Output Wiring Descriptions
This panel has six types of outputs. The location of the outputs’ terminal blocks within this panel are shown in Figure 5. Detail of
the terminal blocks is shown in Figure 11.
Alarm Output Contact Wiring
One alarm output contact is provided. It is Form C and is rated for 0.5A at 24VDC, resistive load. A detail of the alarm output
contact terminal connections is shown in Figure 12. The contact in Figure 12 is shown in the non-alarm position. Determination of
wire gauge for the alarm output contact wiring should consider all factors, including wire loop length, maximum current capacity, and
maximum voltage drop allowable.
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 13. The contact in Figure 13 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 14. 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 15. The wiring
diagram for a notification appliance output using combination audio/visual appliances in central amplified applications is shown in
Figure 18. The wiring diagram for a notification appliance output using combination audio/visual appliances in amplified speaker
applications is shown in Figure 19.
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, 70.7V or 100V audio output, rated for 10, 40, or 80 watts 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 16. The wiring diagram for the audio notification appliance output using audio only appliances in amplified speaker
applications is shown in Figure 17. The wiring diagram for a notification appliance output using combination audio/visual appliances
in central amplified applications is shown in Figure 18. The wiring diagram for a notification appliance output using combination
audio/visual appliances in amplified speaker applications is shown in Figure 19.
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.
