System Sensor SPSRLED — L-Series with LED indoor wall-mount speaker strobe, red housing with FIRE marking.
The speaker and the strobe are driven separately: the speaker sits on a 25 or 70.7 Vrms audio circuit with a rotary-selected wattage tap, while the LED strobe runs from a 24 VDC notification circuit at a candela set on its own rotary switch. LED optics draw far less current than the xenon tubes of the earlier L-Series. A plug-in mounting plate with shorting spring proves the wiring first, and DVM test points allow voltage checks in place.
- Field-selectable candela 15, 30, 75, 95, 110, 135 and 185
- Strobe current 18 mA at 15 cd to 120 mA at 185 cd, 16 to 33 VDC
- Speaker taps 1/4, 1/2, 1 and 2 W, 400 to 4000 Hz
- Minimum output 76 to 83 dBA at 10 ft
- One flash per second over the full strobe voltage range
- 6.5 in × 5.00 in × 2.3 in; 32 to 120 °F
Confirm color and optic: SPSWLED is the white wall version, SPSCRLED the red ceiling version, SPSRL the earlier xenon red wall unit, SPRL a red wall speaker with no strobe. SPSRLED-P omits the FIRE marking, SPSRLED-SP reads FUEGO.

FAQ
Is it compatible with older SpectrAlert devices?
Yes. System Sensor states L-Series with LED devices are electrically compatible with legacy SpectrAlert, SpectrAlert Advance and L-Series devices at 16-33 VDC.
How is the strobe synchronized?
Through UL approved power supplies that support the System Sensor Sync protocol, or with the System Sensor MDL Sync Module.
Can it be mounted on the ceiling?
System Sensor lists its speakers and speaker strobes for wall or ceiling use, but the SPSRLED candela settings (15 to 185 cd) are the wall-unit settings; ceiling models such as SPSCRLED use 15 to 177 cd.
Is a surface back box available?
Yes. The SBBSPRL red wall back box is made for L-Series speaker strobes and speakers.
