Hazardous-location reference using explosion-proof horns and robust amplification.
The bill of materials below links to actual Safsale catalog products. Use the design as a purchasing baseline, then adjust endpoint count, speaker tap settings, zone routing, amplifier or PoE capacity, cable topology, acoustic coverage and backup requirements for the real property.
Sum speaker tap wattage and apply design headroom to size a practical distributed-audio amplifier.
Open toolEstimate PoE ports and power budget for IP speakers, horns, strobes and displays.
Open toolEstimate speaker wattage per zone, amplifier channels and total power by zone.
Open toolEstimate free-field SPL attenuation with distance from a reference speaker rating.
Open toolCount indoor, outdoor, visual and call-box endpoints and add spare capacity for planning.
Open toolEstimate network/paging backup runtime from load and battery energy.
Open toolReview zones, speaker/visual coverage, network, power, backup, triggers and commissioning.
Open toolEach row opens the live Safsale product card.
The reference BOM uses live Safsale product cards for the paging or notification source, amplifier/server, speaker or visual endpoints, network/cabling and optional backup-power items shown on the page.
For distributed 70V/100V systems, add the selected transformer tap wattage of every speaker on the amplifier channel, then add design headroom. Use the Safsale 70V Speaker Load & Amplifier Calculator as a first pass.
Count each powered endpoint, use its maximum PoE draw or IEEE class, and confirm both total switch PoE budget and per-port capability. Use the IP Paging PoE Planner or general PoE Budget Calculator.
No. If the system will be used for emergency or life-safety notification, the actual project must verify audibility/intelligibility, visual coverage, supervision, pathway survivability where required, backup power, listings, sequence of operation and applicable AHJ/project requirements.
Use the Sound Pressure at Distance calculator for a free-field attenuation estimate, then confirm the actual design for room acoustics, background noise, speaker directivity and mounting conditions.
Safsale can quote alternate speakers, horns, amplifiers, IP endpoints, strobes, PoE switching, cabling and backup-power components.
