System Sensor SPSCRLED — two-wire L-Series with LED ceiling-mount speaker strobe, red housing.
Voice evacuation systems need an appliance that carries intelligible speech and a synchronised visual signal from one ceiling opening. The LED optic replaces the xenon flashtube of the earlier L-Series and draws far less current across the candela range, so more appliances fit on a notification appliance circuit. Rotary switches set candela, speaker tap and speaker voltage in the field, and DVM test points let voltage be read without pulling the device down.
- Ceiling candela field-selectable at 15, 30, 75, 95, 115, 150 and 177
- Strobe current 18 mA at 15 cd rising to 115 mA at 177 cd over 16 to 33 VDC
- Speaker taps of one quarter, one half, 1 and 2 watts at 25 or 70.7 Vrms
- Frequency range 400 to 4000 Hz; 520 Hz capable with a compatible panel
- Flash rate one per second; 6.8" diameter × 2.33" deep with lens
Check the letters: SPSCWLED is the white ceiling version, SPSRLED and SPSWLED are wall units with a different candela list, and SPSCRL is the older xenon model.

FAQ
Does it work with older System Sensor appliances?
Yes. It is 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 a System Sensor MDL sync module.
Is a surface back box available?
Yes. The SBBCRL red ceiling surface mount back box makes the assembly 6.9 in. in diameter and 4.83 in. deep.
Can voltage be checked without removing it?
Yes. DVM test points on the face let you measure device voltage without taking the appliance off the ceiling.
