The System Sensor P2WLED-P is a high-efficiency, 2-wire LED horn strobe designed for indoor wall-mount applications. As a veteran-grade fire notification appliance, it features significant advancements over legacy xenon models, specifically engineered to minimize current draw by approximately 40%. This reduction in power consumption allows for more devices per Notification Appliance Circuit (NAC) and simplifies power supply calculations for large-scale commercial retrofits. Designed with a plain, white housing (no lettering), it maintains a professional aesthetic suitable for clean-room environments or architecturally sensitive commercial spaces. For field technicians, the System Sensor P2WLED-P utilizes a universal mounting plate with an integrated shorting spring, permitting the testing of wiring continuity before the device is even installed. It is the direct LED replacement for the legacy FHS-240, P2WL-P, and P4W-P series, ensuring seamless backwards compatibility with existing SpectrAlert Advance and L-Series systems. Precise adjustments are handled via rear-mounted rotary switches, offering field-selectable candela settings (15, 30, 75, 95, 110, 135, 185 cd) and multiple horn tones with high/low volume options. A built-in DVM diagnostic test point allows for rapid voltage measurements directly from the front face, saving critical time during system troubleshooting and EOL inspections. Key Benefits Enhanced Circuit Capacity: Advanced LED technology drastically reduces current draw, allowing for more appliances on a single circuit versus older xenon-based notification units. Retrofit-Ready Compatibility: Engineered for direct replacement of P2W-P and M-507437 units, providing a drop-in solution that is electrically compatible with legacy sync protocols. Simplified Troubleshooting: Integrated diagnostic test points allow for digital voltage meter (DVM) checks without removing the device from the wall. Contractor-Friendly Installation: The plug-in design and universal mounting plate minimize the risk of ground faults and reduce time spent on the ladder. Common Questions How do I set the candela on the P2WLED-P? The unit features a rear-mounted rotary switch that allows you to select between seven candela settings (15, 30, 75, 95, 110, 135, and 185 cd) to meet specific AHJ requirements. Is this device compatible with non-LED L-Series strobes? Yes, the P2WLED-P is fully backwards compatible and can be used on the same circuit as legacy L-Series and SpectrAlert Advance devices using System Sensor synchronization protocols. Can this horn strobe be used for ceiling applications? No, this specific model (P2WLED-P) is UL listed for wall-mount installations only. For ceiling applications, the PC2WLED series should be utilized. Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
