Supplier product reference · reviewed 19 October 2026
Keep the 100W and 200W amplifier variants in one documented family, with load, supply and control scope confirmed separately.
Published identification
Supplier-published entries. Ratings and configuration still require current documentation.
The official source places NV-SR100AD and NV-SR200AD together in a specification table. This page keeps them as one family while retaining both full codes for a sourcing brief. A black amplifier with a coiled-lead handheld microphone is illustrated; the presentation does not establish that a loudspeaker or external lightbar is included.
NOVA describes tone selection, a microphone and two auxiliary switches, but its feature list calls the selection “five sounds” while naming six. The sound entry also differs between the body and table. Those inconsistencies make a current version-specific function schedule more useful than a broad promise of identical control features across all orders.
Procurement checklist
Keep the item identity, physical version and supply scope together. Use the questions alongside the published specifications when preparing a sourcing brief.
Request the exact amplifier reference and a document mapping 100W or 200W output,12V or 24V input and 8Ω or 11Ω load to that version. Do not assume that slash-separated catalogue values describe a universal supply or an interchangeable speaker pair.
Have the proposal list microphone, controller, bracket, leads, speaker and any separately purchased lighting equipment. The source describes auxiliary switching but does not document the supplied external loads. Ask for the relevant interface documents without relying on a product photograph.
Ask the supplier to resolve the five-versus-six tone description and the 110–120dB table versus 120dB body wording. Request the applicable measurement conditions and version-specific control schedule; no acoustic output or legal-use approval is verified on this page.
A speaker and an amplifier are different components. Ask for the documented amplifier output, speaker load, supply arrangement and connector schedule for the proposed system; similar wattage labels do not establish a compatible pair. Keep machine serial number, existing accessory-supply documentation and intended application in the request. This page provides no wiring, sound-level testing or installation procedure.
The family identity is supported by the official table, but the source does not establish a compatible system with either speaker linked here. Emergency-vehicle wording is a supplier application description, not permission to operate a siren or use restricted signals. No safety, acoustic-performance or installation compliance has been authenticated.
This reference is neither a quotation nor a stock, delivery or authorisation commitment. Request a current written proposal from the quoting entity. Preserve the item reference, quantity, destination and included accessories in that proposal so that changes of configuration remain visible.
