The POWERPATH NAC Extender Power Supply is available in two models: the PS-8 and the PS-6. The PS-8 differs from the PS-6 in the NAC output current and in the enclosure size and the PS-8 enclosure can mount up to two addressable control modules. All other features, indicators and capacities are the same.
• 24VDC power limited synchronized outputs. Up to 50 NAC devices per output, maximum line impedance 1.46 Ohms per NAC. • 8 Amp in alarm supply current for the PS-8 (6 Amp in alarm supply current for the PS-6). • Capable of four (4), Class "B" regulated outputs (Maximum of 3 Amps on an output.) •...

BATTERY CALCULATION SHEET is provided on pages 20 and 21. NOTE: The PS-8 enclosure can accommodate two 12VDC batteries up to 12 Ahr in size. Batteries larger than 12 Ahr must be stored in a separate battery enclosure such as the Wheelock BATC Battery Enclosure.
• Always de-energize the POWERPATH completely (Remove both AC and DC power) before repairs. • While the POWERPATH is de-energized, perform a visual and hands on check of all terminals and wires to ensure proper termination. • If intermittent troubles occur, use the trouble latch (SW2 Position 4) to find it.
