Intermatic EK4236S – Frequently Asked Questions

1) Will the Intermatic NIGHTFOX EK4236S photocontrol work on a 277V circuit?
Yes. The NIGHTFOX EK4236S is rated 120-277 VAC, 50/60 Hz, so one part covers 120V residential feeds and 277V commercial lighting branch circuits without stocking separate voltage versions. That range makes it a single SKU you can standardize on across a mixed-voltage property.
2) How much lighting load can the EK4236S photocontrol switch?
Up to 1,650W at 277 VAC, which is enough for a single wall pack or a group of fixtures on one circuit. It handles both HID and LED loads, so it works on older metal halide area lighting and on retrofit LED wall packs. Add up the fixture wattage on the circuit before wiring several fixtures through one control.
3) How does the NIGHTFOX EK4236S mount, and do I need an electrical box?
It uses a threaded stem with a swivel, so it mounts through a knockout in an outdoor electrical box or directly on an outdoor lighting fixture as a permanent install. The swivel lets you aim the sensor north, away from the fixture it controls, which is what keeps the lamp from re-triggering the sensor. It is not a twist-lock unit, so it will not drop onto a standard NEMA locking receptacle on top of a pole head.
4) What happens to the lights if the NIGHTFOX photocontrol fails?
It has a fail-on mode, meaning the lights stay on rather than going dark if the control fails. For a parking lot or an apartment breezeway that is the safe failure direction: you get a daytime-burning fixture as your service call trigger instead of a dark lot and a liability problem.
5) Should I use a stem-mount photocontrol or a twist-lock one?
Stem mount is the right pick when the fixture has no photocontrol receptacle, which is most wall packs, flood lights, and junction-box-fed area lights. You drill or use an existing knockout and wire it in. A twist-lock unit only makes sense when the fixture already has a NEMA locking receptacle built into the top. The EK4236S is the stem and swivel version, with a 1.25 inch stem depth dimension.
6) Will a photocontrol like this hold up on a circuit with voltage spikes?
The EK4236S carries a 255J MOV surge protection element and a conformal coated PCB. The MOV clamps transients coming down the branch circuit, and the coating protects the board against moisture and condensation inside an outdoor enclosure. It also uses a DC relay with zero-crossing circuitry, which switches at the point in the AC cycle where current is near zero and cuts the inrush stress on both the relay and the LED drivers downstream.
7) Do electronic photocontrols drift and start switching at the wrong time of day?
This one uses a non-drift silicon light sensor with an IR filter. The IR filter is the part that matters on an LED retrofit: it keeps heat and infrared from nearby lamps out of the reading so the control responds to actual daylight level, not to the fixture it is switching. Rated life exceeds 10,000 ON/OFF cycles with a 15 year design life, so it is not a part you plan to swap every couple of seasons.
8) Can I use one EK4236S to control several parking lot fixtures at once?
Yes, within the load rating. The EK4236S is rated for single or multifixture HID and LED installations up to 1,650W at 277 VAC. Wire it as a line-side control ahead of the fixture group and keep total connected wattage under that ceiling. Mount the control where nothing it is switching shines back into the sensor.
9) What is the exact part number and color of the NIGHTFOX stem mount photocontrol?
Order Intermatic EK4236S. It is the NIGHTFOX electronic photocontrol in the stem and swivel mount configuration, 120-277V, finished in gray, and made in Mexico. The gray body is the standard utility color that blends against a conduit body or a wall pack housing.
