2.3 WIRING

Review the Operation Section (3.0) in order to select the proper hook-up and use of the POWERPATH.
Set switches and wire the POWERPATH as follows: Terminal locations are shown in Figure 1.
Set Power Supply switch (SW1) for 120VAC or 240VAC operation. See Figure 1.
A. Set Power Supply switch (SW4) for desired output voltage (Down for 24VDC, Up for 12VDC). See
Figure 1.
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 DIP Switch SW9 position 1 & 2 to select Class "A" or Class "B" operation (Off for Class "B", On for
Class "A"). See Figure 1.
D. Dress battery wire down to the back of the enclosure, observing ¼" separation of power limited wire
V.S. non-power limited wiring. See Figure 3.
E. 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 for the PS-12/24-8MP NAC circuits shall not exceed 8.0 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 outputs with a 2.2K Ohm EOLR.
F. Connect the indicating circuit(s) from the FACP to the desired input(s), IN1 and IN2. Connect EOLR to
RET1 and RET2. The value is determined by FACP.
G. Connect desired auxiliary equipment (Door Holder) to the auxiliary output terminals +AUX-. This output
is disconnected upon AC loss or alarm condition. The power is reconnected 30 seconds after AC
power returns or the alarm condition is over.
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 or a 12AH battery depending
on circuit loading, BATTERY CALCULATION SHEET is provided on Sheet 23.
J. Install battery cover between both battery wires and Power Limited Wiring. See Figure 3.
K. Connect AC source. The AC source shall be connected to a dedicated, non-switch power source. The
AC must first be wired into the buildings main electrical power. The conduit entry can be either from the
top or left hand side using the knock-outs. See Figure 3. Connect Earth Ground First.
L. Press Auxiliary Power Reset, SW7 to ensure that Auxiliary Power is present.
M. Close door and secure with 2 screws on side.

2.4 RELAY STATUS CONNECTIONS

COMMON TROUBLE TERMINALS – The common trouble terminals are located on the right bottom side of the PC
Board. The three terminals are labeled "NO", "C" and "NC". When the PS-12/24-8MP is operating normally the "NC"
"C" terminals are shorted, and the "C" "NO" terminals are open. There are five trouble conditions that will cause these
terminals to change state. The relay follows the trouble condition and is not latching.

Table 3: DIP Switch Selection

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.
ON Allows a sync signal on the input to be used by the output.
Generates Wheelock sync signal for synchronizing Wheelock horns
and strobes.
