System Sensor SPWL is a white L-Series indoor wall speaker, dual voltage (25 or 70.7 Vrms), speaker only with no strobe.
Voice evacuation and tone systems need a speaker at wall positions a horn would otherwise occupy. The SPWL is that speaker on its own, for locations already covered by a separate strobe or where no visible signal is required. Voltage and power tap are set with rotary switches on the unit, so one part number covers every tap an installer might need.
