The night nPP16 ER Series relay pack is used to switch luminaires powered via an emergency circuit. Ideal for use along side a standard nPP16 relay pack that controls a zone's normal powered lighting, the nPP16 ER is designed to switch up to 16 Amps of lighting load. The nPP16 ER's two RJ-45 connectors make control wiring with standard CAT-5 cabling easy and clean. An elongated chase nipple facilitates attachment directly to a junction box or fixture through a 1/2 inch~157; knockout. A push button and LEDs are also provided which allow users the ability to manually alter settings or test emergency operation.
