System Sensor SPSWLED — L-Series with LED two-wire wall speaker strobe in white, marked FIRE.
It pairs a dual-voltage transformer speaker with an LED strobe, so one appliance carries both the audible and the visible signal. The LED draws markedly less current than the xenon flash tube of the earlier L-Series speaker strobes, letting more appliances sit on a circuit before the power supply becomes the limit.
