POWERPATH PS-8-LP Installation Instructions Manual page 14

NOTE: The maximum number of NAC appliances is dependent upon the field wire gauge used and the
total current draw of the Appliances on the NAC circuit.
C. Connect notification appliances to desired outputs OUT1 – OUT4. See Figure 6.

The POWERPATH has in-out wiring terminals that accept two #18 to #12 American Wire Gauge
(AWG) wires at each screw terminal. Strip leads 3/8 inch and connect to screw terminals.

Separate all in-out wire runs on supervised circuits to insure integrity of circuit supervision. The polarity
shown in the wiring diagrams and on the circuit boards is for operation of the appliances. The polarity
is reversed by the POWERPATH during supervision.

Total load for the PS-8-LP NAC circuits shall not exceed 8.0 Amps. Total load for the PS-6 NAC circuits
shall not exceed 6.0 Amps.

Total load of any Class "B" output circuit shall not exceed 3.0 Amps.

Total load of any Class "A" output circuit shall not exceed 3.0 Amps.
Terminate unused Class "B" outputs and the last appliance on an output with a 10K Ohm EOLR. Do not
D.
terminate Class "A" outputs with an EOLR, use jumper wires, see Chapter 6.0 on sheet 22 for example
drawings.
Connect the indicating circuit(s) from the FACP to the desired input(s), IN1 and IN2. Connect FACP
E.
compatible EOLR's to RET1 and RET2.
In order to use the audible silence feature, connect a 24V or NAC output to the PS-8-LP (PS-6) SIL input

terminal.
G. If all NAC appliances must activate at the same time, connect "OUT4" from the first PS-8-LP (PS-6) to the
"IN1" of the second PS-8-LP (PS-6). Next connect the "IN1 RET" of the second PS-8-LP (PS-6) to the next
PS-8-LP (PS-6) "IN1. Connect a 10K EOLR to the "IN1 RET" terminal on the last PS-8-LP (PS-6).
If NAC appliances must be activated sequentially (not all at the same time) connect the SYNC BUS/SYNC
BUS RET between PS-8-LP (PS-6).
H. Connect desired auxiliary equipment to the auxiliary output terminals +AUX-. See Sheet 33, Section 8.0,
for the List of Compatible AUX Devices.

Total load of the AUX output shall not exceed 0.02 Amps during 60 hour battery backup in the Constant
Power (CP) mode, if using standard 12 Ahr batteries.

Total load of the AUX output shall not exceed 0.24 Amps during 24 hour battery backup in the Constant
Power (CP) mode, if using standard 12 Ahr batteries.

Total load of the AUX output shall not exceed 0.075 Amps during 24 hour battery backup in the
Constant Power (CP) mode for the PS-6, if using standard 7 Ahr batteries.

Total load of the AUX output shall not exceed 2.5 Amps in the Managed Power (MP) mode.
I. Connect system trouble relay terminals as desired.
