Fixed Position Mounting
The K4000 Series Fixed Position Mounting Photo Controls are
thermal-type photo controls that t into a standard outlet box, post
lamp, or wall pack. The photo controls provide dusk-to-dawn lighting
control along with a delay action, which eliminates loads switching OFF
due to car headlights and lightning. The thermal-type controls feature a
cadmium sulde photocell and a sonic-welded polycarbonate case and
lens to seal out moisture. The design utilizes a dual temperature
compensating bimetal and composite resistor for reliable long life
operation over ambient temperature extremes.
