Essential Info

Intermatic has a complete line of photo sensors to optimize your lighting control system for both simple and complex site lighting applications and can even stagger ON lighting as outdoor light levels decrease. When using the photo sensor input module in conjunction with digital photo sensors the system becomes capable of delivering up to 14 different levels of lighting in reaction to sensed ambient light.

All devices have an RJ45 connector and are daisy-chained using Cat. 5 cable to the EM1408MC, EM1416MC Master Relay Panel and/or the EM1408SC (8 circuits) or EM1416SC (16 circuits) Slave Relay Panels. The system is laid out in series (A to B, B to C, C to D) so there is no need to figure out a star or other topology making setup much easier. Once programmed, your lights will come on and off at the times you set. With 32 schedules available every day of the year the options are nearly endless. Never forget to turn the lights off before bed and burglars watching the house will never know you are on vacation.
