The Wacker Neuson Back Up Alarm is a genuine OEM component designed for the RD and CB14B series tandem and vibratory rollers, including the RD7H-ES, RD11, RD16-90, RD16-100, RD27-100, RD27-120, and CB14B-900/1000 models. As a direct OEM replacement, part is sourced and specified by Wacker Neuson to match the original unit exactly, ensuring proper fit within the machine's safety warning system. This alarm is built to the same output and operational standards as the unit it replaces, giving you confidence that the safety system will perform as intended from the moment it is installed. If your roller is sounding no warning or a degraded audible signal when reversing, the is the correct OEM part to restore full compliance.
Key Features
- Genuine OEM Audio Output Spec — Sourced directly from Wacker Neuson, this alarm meets the original decibel rating and activation threshold specified for these roller models — not an approximation.
- Direct Plug-In Replacement — Connects to the existing wiring harness using the original mounting points, so installation requires no splicing or bracket modification.
- Broad RD and CB14B Series Coverage — Confirmed fitment across the RD7H-ES, RD11, RD16-90, RD16-100, RD27-100, RD27-120, and CB14B-900/1000 tandem roller families.
- Keeps Reverse Warning Active — A functioning back up alarm ensures the machine audibly alerts ground workers any time the roller reverses — a routine motion during asphalt and soil compaction passes.
- Worksite Safety Compliance — Back up alarms on ride-on and walk-behind rollers are a standard worksite safety requirement; replacing a failed unit with the correct OEM part supports compliance with applicable safety regulations.
A back up alarm is an audible warning device that activates automatically whenever the machine is placed in reverse. On tandem vibratory rollers, reversing is a frequent and normal part of compaction work, making a functioning alarm essential for alerting nearby workers and ground personnel of the machine's changing direction of travel. When the alarm fails — whether through electrical fault, physical damage, or normal wear — the machine loses an important layer of personnel safety and may fall out of compliance with jobsite safety requirements until the unit is replaced.
