Main Supply Circuit
The AC terminals are located on the power supply board. The power supply board supervises the main AC
power and provides indication that the AC power is absent.
Figure 1
The terminals are rated at 120 VAC/240 VAC 50/60 Hertz and are marked so accordingly on the board. The
earth ground connection is marked as “G” and is the furthest connection from the line voltage connection.
The AC input power ratings:
Maximum of 5.1A at the nominal 120 VAC rating.
Maximum of 3A at the nominal 240 VAC rating.
Rechargeable Battery Circuit
The battery charging circuit is provided on the power supply board. Terminal connections are provided to con-
nect wire leads for battery connection. The battery must be a recognized or listed sealed lead acid battery or
equivalent.
The battery charging voltage is approximately 27.3 VDC and the circuit is supervised. The battery circuit is
protected with a non-replaceable 7 amp poly switch located on the main circuit board. The maximum battery
charging circuit is 1.0 amp DC.
The battery circuit is rated for 8 to 55 AH batteries and the cabinet will house up to two 18 AH batteries. The
batteries will operate the panel for at least 24 hours and 5 minutes of alarm. In order to determine the minimum
size batteries for standby and alarm times desired, the installer must complete a battery calculation work sheet
in order to determine the minimum battery size for a particular application. For reference, the battery calcula-
tion work sheet is attached as Appendix A. Complete standby battery calculations must be completed to ensure
adequate battery sizes are provided.

Separation of Circuits - Power Limited, Non-Power Limited, High Voltage Wiring
The main AC power connection is considered high-voltage and non-power limited. Battery conductors, and
the alarm, supervisory, and trouble relays are non-power limited. All remaining circuits are low-voltage, power
limited connections.
Proper separation must be maintained between the circuits listed above. All separations in the different wiring
must be maintained by at least 0.25 inches and the wire insulation must be for the higher voltage.
In the enclosure there are sufcient knock outs located around the periphery of the cabinet to allow the installer
to maintain separation between power limited and non-power limited connections. The main AC power connec-
tion should be made on the left side or top left of the cabinet.
Notication Appliance Circuits (NACs)
The PSN-1000 is equipped with six NAC circuits. Each of the circuits is rated for a continuous 3 amps at 24
VDC. The outputs are supervised and regulated. The NACs reverse polarity upon activation and the board and
illustrations are marked accordingly.
The NAC circuits can be congured for Class A operation. Class-A operation is accomplished by using a pair of
NAC circuits. Therefore, the PSN-1000 can provide 3 Class A circuits, each rated for a continuous 3 amps at 24
VDC. The outputs are supervised and regulated.
NAC circuits are power limited and the type of output is selectable. The NACs may be congured for strobe
synchronization with Potter/AMSECO, Wheelock, Gentex, or System Sensor strobe devices as shown compat-
ible in this document and the installation instructions.
The maximum impedance is a function of the load being applied to the circuit. In order to calculate the maxi-
mum impedance as follows
(Alarm Current of Notication Appliances) X (Wire Resistance) < 3 volts.
The NAC circuits may be congured for Class A, Style Z or Class B, Style Y.
The panel has ground fault detection on the NAC circuits. The impedance to ground for ground fault detection is
0 ohms.

Input Circuits
The panel is equipped with two input circuits, I1 and I2. These circuits are dry-contact monitoring inputs, and
can be used in class B mode only. I1 and I2 are low voltage, power limited, and supervised.
Maximum wiring resistance = 100 ohms.
Maximum wiring capacitance = 1 uF.
Maximum wire length = 10,000 feet.

P-Link from Control Panel
The control panel communicates with the PSN-1000 via the main P-Link circuit. This connection is electrically
isolated from the rest of the PSN-1000. All supervision of the PSN-1000 is conducted through this connection.
Figure 6
P-Link Repeater
The P-Link repeater output allows for system expansion by reconditioning and repeating all P-Link communi-
cations. The PSN-1000 repeater output provides an additional 1 amp at 24 VDC which can be used to power
additional P-Link devices such as LCD Annunciators and/or SLC Loop expanders.
Wiring is fully supervised and power limited. Any connection to ground of 0 ohms will be annunciated as a
ground fault.
P-Link Current = 1 Amp Each
P-Link Voltage = 24 VDC
Maximum wire length = 6,500 feet.
Maximum wire resistance = Maximum wiring resistance is based on load.
Calculate using the following equation
(Total P-Link Alarm Current) x (Wire Resistance) < 6 volts.

Releasing Device Circuit
The releasing circuit is fully supervised and power limited. The releasing device circuit is a NAC that is pro-
grammed to control a releasing device such as a solenoid or squib.
The output is a constant 24 VDC, regulated output. When connected to a releasing device, the circuit is a spe-
cial application circuit and listed with the devices as outlined in Section 6 of this ULLD document.
The maximum current is 3 amps. The maximum line impedance is calculated using the following formula.
Rmax (ohm) = (24V-Vmin-0.95V)/I total
Vmin is the lowest voltage operation of the connected devices.
I total is the total current of the connected devices.
When a NAC is used as a releasing circuit, the End of Line Diode (EOLD) assembly must be installed. The
EOLD is Potter part number 3005012 and must be installed in accordance with the installation manual.
