Intermatic FF4H – Frequently Asked Questions

1) Will the Intermatic FF4H spring wound timer work on a 277V lighting circuit?
Yes. The FF4H is rated 125-277 VAC at 50/60 Hz, so the same timer handles a 120V branch circuit in a restroom or a 277V commercial lighting circuit in an office or warehouse. That single voltage range is why facilities standardize on it instead of stocking separate 120V and 277V timers.
2) Can a spring wound countdown timer replace an existing single-gang wall switch?
That is exactly what the FF4H is built for. It drops into the place of any standard or decorator single-gang wall switch, and wiring is done through up front teeter-type terminals so you are not fishing screws at the back of the box. The device body measures 4.125 by 1.75 by 1.25 inches, so confirm your existing box has the depth for the 1.25 inch dimension.
3) Does the Intermatic FF4H timer need a neutral or any power to run?
No power at all. The FF4H is spring wound, so the timing mechanism runs off the wound spring rather than the circuit it controls. Nothing to lose when the power blips, and no electronics to reset. It is an SPST device, meaning it simply opens the circuit when the wind down reaches zero.
4) Will a spring wound timer switch work with LED fixtures, or do I need an electronic timer?
LED is fine. Because the FF4H is a mechanical SPST switch that simply makes and breaks the circuit, it works with incandescent, fluorescent, CFL and LED loads alike. There is no load-sensing electronics to be confused by low-wattage LED drivers, which is the usual failure with digital timer switches on LED retrofits.
5) Is a 4-hour timer the right choice for a warehouse exhaust fan, or should I pick a shorter interval?
Four hours is the maximum on the FF4H, and ventilation and air movement is one of the applications it is listed for, along with indoor and outdoor lighting control and motor control. Pick the 4-hour version when the load legitimately needs to run a half shift, such as a bathroom or shop exhaust fan or a stairwell light bank. For short-dwell spots like a janitor closet or a restroom light, a shorter maximum from the same FF Series keeps someone from winding on four hours of unnecessary runtime.
6) Can the FF4H countdown timer switch a motor load directly?
Motor control is one of the applications Intermatic lists for the FF4H, so it is used on fans, blowers and similar rotating loads rather than lighting alone. It is a single-pole single-throw device, so it interrupts one leg only; a 277V or three-phase motor circuit that must be broken on more than one pole needs the timer driving a contactor instead of feeding the motor directly.
7) Will the Intermatic FF4H match the other switch plates in a commercial corridor?
The FF4H comes in silver with a brushed metal look switch plate, so it reads as brushed stainless rather than white or ivory plastic. In a building already fitted with stainless or brushed nickel device plates it blends in; against standard white decorator plates it will stand out, which some property managers actually want so tenants can find the timer.
8) What model number do I order for the 4-hour Intermatic commercial spring wound timer, and where is it made?
The part number is Intermatic FF4H, the 4-hour maximum member of the FF Series commercial countdown timers, in silver. Country of origin is Tunisia, which is the detail government and institutional procurement usually needs for their sourcing paperwork.
