Releasing Device Circuit

**** The releasing circuit is fully supervised and power limited. The releasing device circuit is a NAC that is programmed 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 special 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.

Municipal Box Connection

When programmed as a municipal box connection, the circuit is power limited, is supervised for open and short circuit conditions and provides a local energy connection.

• Trip current: NAC1-NAC6 = 3 Amps
• Max Voltage:   24 VDC

The panel has ground fault detection on municipal box connection circuits. The impedance to ground for ground fault detection is 0 ohms.

Relay Outputs

The panel has a dedicated trouble relay and low AC relay. The dedicated trouble relay is a failsafe trouble relay that changes position anytime a trouble condition occurs.

The contact rating is 24VDC / 3.0A, 125VAC / 3A, Power Factor: 1.0. These outputs are non-power limited and not supervised. However, they are power- limited if the power supply to the connected devices is power limited.

General Wiring Information

The cabinet has various conduit knockouts located around the cabinet for ease of wire installation. In addition, this method provides a means to separate different types of circuit to reduce electrical interference, transient voltage or voltage ratings.

The enclosure requires the use of power limited and non-power limited wiring on the main board as well as within the enclosure. Power limited wiring is to remain separated from non-power limited by a minimum or 0.25 inches and all cabling should be insulated to the higher voltage.

When the panel is installed, the National Electrical Code (NEC, NFPA 70) should be followed for the proper installation and separation of power limited and non-power limited circuits. The mixing of power limited and non-power limited should be avoided.

Functionality

The PSN-1000 & PSN-1000E provide power and communication expansion capability to the PFC-6000 series control panels. The PSN-1000 provides an electrically isolated Plink repeater output, providing additional power and communications distance. The larger cabinet of the PSN-1000E provides locations for mounting additional SLCE-127 SLC expanders.

The 6 NAC circuits are configured and controlled by the main control panel.

he PSN-1000 transfers from AC to battery instantly upon AC failure or brownout. The trouble relay will indicate the low AC condition after the Low AC Report Delay has elapsed.
