The LMIO-301 works in conjunction with either the LMPO-200 exterior or LMPS-6000 skylight low voltage photocell heads.

Can I just disconnect the LMIO-310 Photocell Input Module from the Lighting Control Panel to just run off of the events I have set for the outside lights without any problems?

Asked by: dwell970
The answer to your question is yes you can remove the LMIO 301 from the panel and just use your programming events but the events that were set to use the protocell will not go into effect because the LMIO-301 is the interface between the panel and the photocell. It allows you to create a schedule which controls your lights through the LMIO-301 by the photocell.
