System Sensor SPSWLED-CLR-ALERT is an L-Series with LED 2-wire speaker strobe for indoor wall mounting, white, with ALERT marking and a clear lens. The LED strobe draws significantly less current than older xenon strobes across the full candela range, which gives more design flexibility on notification appliance circuits and reduces power supply requirements. Candela, speaker voltage and power are set with rotary switches, and Digital Volt Meter (DVM) test points on the face allow device and end-of-line voltage checks without removing the appliance.
