    How to choose alarms & accessories

    Pick the housing for the environment

    Metal-housing alarms suit harsh worksites and special vehicles; plastic housings cover standard commercial-vehicle duty. Both X138, X139 and X148 series models carry waterproof housings.

    Match the trigger level to your system

    Alarms are available with high or low trigger levels — confirm whether your reversing camera or 360° AVM system output matches before ordering.

    Plan placement for audible coverage

    Mount the alarm on the rear or sides where pedestrians and operators are most exposed — confirm mounting points and cable reach with our engineer for your vehicle model.

    Combine with cameras for full coverage

    Pair an audible-visual alarm with reversing cameras or a 360° AVM system so drivers see and nearby workers hear the same maneuver — request a matched bundle from our engineer at low MOQ.
