Intermatic EK4736S – Frequently Asked Questions

1) Will the Intermatic NIGHTFOX EK4736S photocontrol work on a 277V parking lot circuit?
Yes. The EK4736S is rated 120-277 VAC, 50/60 Hz, so the same unit covers 120V building perimeter circuits and 277V commercial lighting branch circuits. That wide range is why it gets specified for parking lot and area lighting where the voltage varies by building. At 277 VAC it handles up to 1,650W of connected load, enough for single or multi-fixture HID and LED runs.
2) Can the EK4736S switch LED fixtures, or is it only good for HID?
It handles both. The switching is done by a DC relay with zero-crossing circuitry rather than a mechanical thermal element, which limits the inrush stress that LED drivers put on contacts, and the unit is rated past 10,000 ON/OFF cycles. Load limit is 1,650W at 277 VAC, covering single or multi-fixture HID and LED installations.
3) Is a stem-and-swivel photocontrol like the EK4736S the right choice, or should I use a twist-lock button type?
Go with the stem-and-swivel EK4736S when there is no NEMA twist-lock receptacle on the fixture. It threads into a knockout on an outdoor box or fixture housing and you aim the lens by hand. If your wall pack or shoebox already has a photocontrol receptacle on top, a locking-type control drops in without any box work. Both do the same job electrically; the difference is purely how the fixture is prepped.
4) What happens to the lights if this photocontrol fails?
The EK4736S operates in fail-ON mode. If the control fails, the connected lighting stays energized rather than going dark, which is what a facility wants on security and egress-adjacent exterior lighting. You will see lights burning during the day, which is the maintenance signal to swap the control.
5) Does this Intermatic photocontrol have built-in surge protection for lightning-prone sites?
There is a 255J MOV surge protection element built in, so transients on the line are clamped before they reach the relay and the connected fixtures. Combined with the conformal coated PCB, which seals the board against moisture and dust, it is built for pole tops and exposed wall packs rather than sheltered locations.
6) Will this photocontrol drift out of calibration and start switching at the wrong time of day?
The sensor is a non-drift silicon type with an infrared filter, so its turn-on point stays consistent over years of service instead of creeping the way older cadmium sulfide cells do. The IR filter also keeps heat from nearby HID lamps or headlights from skewing the reading. Design life is 15 years.
7) What is the exact part number and where is the EK4736S made?
The manufacturer part number is EK4736S, Intermatic's NIGHTFOX series electronic photocontrol with top lens, stem and swivel mount, rated 120-277V. Country of origin is Mexico.
8) What color is the EK4736S and will it blend in on a light-colored building?
Gray housing. For property managers standardizing exterior controls across a portfolio, that neutral gray reads fine against most aluminum and concrete, and since the head swivels on the stem you can orient it so the lens faces away from the street view.
