System Sensor SCWLED L-Series 24V LED Ceiling-Mount Fire Strobe, White
The System Sensor SCWLED L-Series LED Ceiling-Mount Fire Strobe is a white, 24V DC visual notification appliance designed for ceiling-mounted fire alarm applications. Its LED technology provides lower current draw than older xenon strobes, helping improve notification appliance circuit flexibility and reduce power-supply requirements.
Seven field-selectable candela settings allow the visual output to be configured for different installation requirements. Built-in digital voltage meter diagnostic test points let technicians measure device voltage without removing the strobe from the ceiling, supporting faster troubleshooting and end-of-line voltage checks.
The SCWLED features a plug-in design with minimal backbox intrusion. Its universal mounting plate incorporates an onboard shorting spring, allowing installers to check wiring continuity before attaching the notification appliance.
