2.3 WIRING

Review the Operation Section (3.0) in order to select the proper hookup and use of the POWERPATH
Set switches and wire the POWERPATH as follows: Terminal locations are shown in Figure 2.
A. Set Power Supply switch (SW1) for desired output voltage (Open for 24VDC, Closed for 12VDC). See Figure 1 (Detail A
and B).
B. Set output DIP Switch(s) to follow corresponding input (IN1, IN2) and desired output mode. See Table 3 DIP Switch
Selection and DIP Switch Settings Section (3.2).
C. Set Logic Board switches SW1 and SW2 to select Class "A" or Class "B" operation (Open for Class B, Closed for Class A).
See Figure 1 (Detail A and B).
CAUTION: The PS-12/24-8 POWERPATH can provide a full 8 AMPS of current during an alarm condition for 5 minutes
with a 7AH battery or 15 minutes with 12AH battery . (A 7AH or 12AH battery is required.). Exceeding these limits may result
in loss of power.
D. Connect notification appliances to desired outputs OUT1 – OUT4. See Operation Section (3.0).
• 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 inches 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 FACP during
supervision.
• Total load of any output circuit shall not exceed 2 AMPS.
• Terminate unused outputs with a 22K OHM EOLR.
E. Connect the indicating circuit(s) from the FACP to the desired input(s), IN1 and IN2. Connect End-of Line Resistors to
RET1 and RET2. Value is determined by FACP.
F. Connect desired auxiliary equipment to the auxiliary output terminals –AUX+.
CAUTION: For the Ground Fault Detection Circuit to operate, the 22K OHM RESISTOR/WIRE ASSEMBLY must remain
connected between (+) AUX and chassis ground as shown in Figure 1. If this connection is broken or disconnected, the Ground
Fault Detection Circuit will be DISABLED and ground faults will NOT result in a TROUBLE condition.
G. Select AC Trouble Delay Option. (Unit is factory set for 1 minute. Remove J1 for 6 hour delay.)
H. Connect trouble relays as desired.
I. Connect backup batteries. Observe correct polarity and voltage. For 12VDC, use a single 12V battery. For 24VDC, use two
of the same connected in series. Use either a 7AH battery for 5 minutes of alarm or a 12AH battery for 15 minutes of alarm.
J. Connect AC source. The AC must first be wired into the buildings main electrical power. The conduit entry can be either
from the top using knock-outs or right side in the transformer area. See Figure 3.

Switch Position
ON Selected output to be controlled by Input 1 (IN1+, IN1-) (DRY1)
OFF Selected output to be controlled by Input 2 (IN2+, IN2-) (DRY2)
ON Generates Code 3 temporal signal on this output.
N/A Used only in the Wheelock sync mode.
ON Allows a sync signal on the input to be used by the output.
Generates Wheelock sync signal for synchronizing Wheelock
horns and strobes.
