The new L-Series outdoor weatherproof devices offer significant improvements in current draw and power supply utilization compared to previous generation SpectrAlert Advance outdoor appliances. In addition, all L-Series outdoor notification appliances are NEMA 4X and IP56 rated without having to seal the backbox. Additional caulk and sealant are not required on the backbox allowing for a faster, cleaner installation. Plus, leveraging LED technology for the strobe devices improves design flexibility for notification appliance circuits (NACs) while also reducing power supply requirements, allowing for simpler and lower-cost installations.
