Sloan EL-1500-L-AD Water Closet Electronic Sensor Replacement - 1 Hour Sentinel Flush

The Sloan EL-1500-L-AD is a sensor for Regal ESS, Royal ESS and Royal ESS TMO.

The EL-1500-L-AD is a sensor replacement kit for Optima® ES-S style flushometers. The kit contains the Sloan water closet sensor. This sensor can only be used on Sloan Optima® ES-S style flushometers. The EL-1500-L-AD sensor is modified to include a sentinel flush every hour and is intended for flushometers operating with a 24V electrical supply. All of Sloan’s sensor flushometer models operate by means of infrared sensor. In this application the sensor emits a beam of infrared light, when a user steps in front of the water closet or urinal, that infrared light ‘bounces’ off the user reflecting back to an infrared detector in the sensor. Infrared light, like visible light, will reflect back with greater intensity off brighter and more reflective surfaces. Sloan’s optical engineers understand this and Sloan designs its sensor to work within a general window of reflective environments typically found in a public restroom.

Common Questions

What flush valves does this part fit?

Sloan's own parts data lists this as fitting Regal ESS, Royal ESS, Royal ESS TMO and Sloan ESS. Match the model or series stamped on your existing flushometer before ordering -- Sloan changes internal parts between series, so a wrong part number is a common return.

Is this a genuine Sloan part?

Yes. The EL-1500-L-AD is a factory-original Sloan Valve Company replacement part, not an aftermarket equivalent.
