Intermatic EK4536 – Frequently Asked Questions

1) Will the Intermatic EK4536 photocontrol work on a 120V circuit and a 277V circuit, or do I need separate parts?
One part covers both. The EK4536 NIGHTFOX photocontrol accepts 120-277 VAC, 50/60 Hz, so the same unit goes on 120V residential-style area lights and 277V commercial lighting branch circuits. That matters if you maintain mixed-voltage sites and want one photocontrol on the truck instead of voltage-specific stock.
2) Is this photocontrol LED compatible, or will it chatter and fail on LED fixtures?
The NIGHTFOX EK4536 is built for LED. It uses a DC relay with zero-crossing circuitry so the contacts close at the zero point of the AC waveform, which is what keeps the inrush from LED drivers from welding or eroding contacts the way it does on older thermal photocontrols. A non-drift silicon light sensor with an IR filter also keeps it from reacting to the fixture's own LED output, which is the usual cause of cycling on retrofits.
3) How many wattage of fixtures can I put on one NIGHTFOX EK4536 photocontrol?
Up to 1,650W at 277 VAC, HID or LED. That is enough to switch a group of fixtures off a single control rather than one per pole, so a parking lot or perimeter run can be ganged through one photocontrol as long as the total connected load stays under that figure. Total your fixture input watts, not lamp watts, before you decide how many to put on it.
4) Is this a locking type (twist-lock) photocontrol or a stem/button mount?
It is a locking type unit, the style that twists into a 3-prong NEMA twist-lock receptacle on top of a shoebox, wall pack, or pole-mount fixture. If the fixture you are servicing has a threaded stem hole or a button-style opening instead of a round twist-lock receptacle, the EK4536 is not the part for that opening.
5) How tall is the EK4536, and will it clear inside a fixture's photocontrol shroud?
Height is 2.75 inches. Measure from the top face of your twist-lock receptacle up to the inside of the shroud or house-side shield before you commit, since that 2.75 inches is the body plus dome that has to sit above the receptacle.
6) Does this photocontrol have surge protection for outdoor pole lighting?
Yes, a 510J MOV is built in to clamp transients, and the circuit board is conformal coated for moisture resistance. For pole-top and perimeter installations, that pairing is what keeps a photocontrol alive through storm-season switching surges and condensation inside the fixture head.
7) How long should a NIGHTFOX photocontrol last before it needs replacing on a maintenance schedule?
Internal components are engineered to a 15-year service life, and the unit is rated for more than 10,000 ON/OFF switching cycles. At roughly one cycle a day for dawn/dusk duty, that cycle count is well beyond a normal relamp interval, which is the point for a property manager trying to stop sending a lift truck out for failed photocells.
8) How do I identify the EK4536 among other photocontrols on a site once it is installed?
By color: white housing with a blue band. Intermatic uses that band for quick visual identification of the grade from the ground, which helps when you are standardizing a campus and want to spot the odd fixture still running an older control. The manufacturer part number is EK4536.
9) What kind of jobs is this photocontrol intended for, and is it overkill for a single wall pack?
It is an outdoor lighting control sized for single or multi-fixture HID and LED installations, so a lone wall pack is well within it and so is a ganged parking lot or perimeter run up to 1,650W. Typical uses are commercial building exteriors, parking and area lighting, industrial perimeter lighting, multi-unit residential, retail and office complexes, municipal lighting, and LED retrofits. If you only need to control a single small fixture and never plan to add load, a lighter-duty control will do the job, but nothing about this one restricts it to large loads.
