As the name suggests, the nPS 80 power supply contributes power to the night system. By connecting directly to the night communication bus, the nPS 80's generated power (up to 80 mA at 15 VDC) is accessible to any system device. For simplifying installation, the nPS 80 has an elongated chase nipple. This feature allows it to be attached either directly through a 1/2 in knockout into a junction box or inside an adjacent box for meeting specific local code requirements in ceiling plenums. The nPS 80 has two RJ-45 ports, each that is current limited to 40 mA, making wiring with standard CAT-5 cabling easy and clean.
