It combines an audible sounder with a visible LED strobe in a single white ceiling unit, reducing installation time and hardware count compared to separate devices. Low frequency sounders are increasingly required by code for sleeping areas, where research shows the lower tone is more effective at waking occupants, particularly the elderly and those with hearing loss. This unit is sold individually and is installed by licensed fire alarm technicians or electricians working on life safety systems.\u003c\/p\u003e\u003cp\u003eThe PC2WLED-LF is intended for ceiling-mount installation in residential and light commercial applications where notification appliance codes require both audible and visible alert output. Typical deployment locations include hotel guest rooms, dormitory sleeping areas, assisted living facilities, and residential occupancies subject to NFPA 72 low frequency requirements. The white housing is suited for standard drop-ceiling or drywall ceiling surfaces where a low-profile, unobtrusive device is preferred.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCombined low frequency sounder and LED strobe in one ceiling-mount unit\u003c\/li\u003e\n\u003cli\u003eWhite housing blends with standard ceiling finishes\u003c\/li\u003e\n\u003cli\u003eLow frequency audio output suited for sleeping area notification compliance\u003c\/li\u003e\n\u003cli\u003eLED strobe provides visible alarm notification\u003c\/li\u003e\n\u003cli\u003eSingle-unit design reduces wiring points versus separate sounder and strobe devices\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style notification appliance for use on compatible fire alarm notification appliance circuits (NAC) in life safety systems.

De-energize the notification appliance circuit at the fire alarm control panel before wiring or removing any device. Polarity must be observed on supervised NAC circuits. Verify end-of-line resistor placement and circuit supervision after installation per the control panel manufacturer requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Ceiling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDevice Type\u003c\/strong\u003e: Low Frequency Sounder Strobe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SYSTEM SENSOR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PC2WLED-LF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SYSTEM SENSOR","offers":[{"title":"Default Title","offer_id":51557329338674,"sku":"PC2WLED-LF","price":292.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15b286b43fa6845f8b5d1a447f3f6c0a.jpg?v=1786385819","url":"https:\/\/voomisupply.com\/products\/system-sensor-pc2wled-lf-low-frequency-sounder-strobe","provider":"Voomi Supply","version":"1.0","type":"link"}
