System Sensor SPSRLED-SP — two-wire L-Series with LED speaker strobe, wall mount, red, with FUEGO lettering.
System Sensor lists this number as 2-WIRE, SPEAKER STROBE LED RED WALL FUEGO, so SP is the Spanish print option and nothing about the electronics. LED replaced the xenon flashtube at far lower current, which governs how many appliances a circuit carries. Candela, line voltage and tap are rotary switches.

The suffix is the marking, not the device: SPSRLED-P is plain, -B bilingual and bare SPSRLED the base red wall number. SPSCRLED is the red ceiling version, whose upper candela steps are 115, 150 and 177. SPRL, the speaker with no strobe, is louder at every tap: 79 to 88 dBA.
