Supplier product reference · reviewed 18 October 2026
An amplifier, operator panel and microphone source entry whose speaker load and machine interface need separate documentation.
Published identification
Supplier-published entries. Ratings and configuration still require current documentation.
NV-SR100CD is an electronic siren-control reference, not a forklift reversing alarm or a complete sound-output assessment. The source image shows a finned amplifier enclosure, separate button panel and hand microphone. Its panel carries SLS-171 lettering, whereas the official specification table names NV-SR100CD. The supplier should identify which panel and amplifier revisions form the offered assembly.
The body describes selectable tones, microphone priority, adjustable output and controls for additional lights. These are configuration questions rather than proof that an existing warning bar will connect to this controller. The table lists 100W and 8 ohms, but does not establish the supplied speaker, acoustic coverage, continuous duty or installed sound level. No speaker is added to the prepared image.
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 an itemised list for amplifier, controller, microphone, speaker if any, harnesses and mounting parts. Ask the supplier to reconcile the pictured panel lettering with the NV-SR100CD table. The enclosure dimensions do not describe every separate component or establish the clearance required in a particular cab.
Confirm whether the quotation is for a 12V version, a 24V version or a documented multivoltage assembly. Obtain load and interface documentation for the actual speaker and controlled lights. The ambiguous 50mV sensitivity wording should be explained rather than converted into a microphone or speaker specification by assumption.
Identify the required warning purpose and the applicable site or jurisdiction rules before selecting tones. A catalogue reference to emergency vehicles does not establish permission to use emergency signals elsewhere. Ask for the relevant operating documents; this page provides no wiring, siren-use or safe-audibility procedure.
A siren amplifier is not automatically an alternative to a forklift reversing alarm. Preserve the intended function, power supply, speaker load and equipment documentation in the request. This reference gives no installation or operational instruction and makes no promise of compliance or compatibility.
The official body and table support assembly identification and procurement questions. Sound pressure, safe audibility, legal use, load compatibility and complete kit contents remain unverified supplier-specific matters.
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.
