Universal alarm is generally used for small and medium-sized excavators, and high decibel warning sound effectively alerts nearby pedestrians and vehicles to avoid dangerous areas.

Car back up alarm, especially the industrial - type one, serves as an excellent backup alarm. It is designed to be highly suitable for harsh working environments. With a universal size, its installation process is a breeze. This remarkable car back up alarm plays a crucial role in enhancing safety within the construction area. Its loud and clear sound can effectively alert pedestrians and staff in the vicinity of large equipment.Moreover, the car back up alarm's unique features make it stand out among other similar products. It provides reliable warning signals just like a vigilant guardian. Multiple car back up alarms can be installed in different positions around the construction site or industrial area to ensure comprehensive coverage. Their presence significantly reduces the risk of accidents caused by the operation of large machinery and vehicles, making the working environment much safer.

B20 series white noise backup alarm can provide workers and pedestrians with clearer and more distinct warning sounds in loud noise environments, without producing sharp noises like traditional backup alarms, thereby reducing listener fatigue and discomfort.

B30 series white noise backup alarm can provide workers and pedestrians with clearer and more distinct warning sounds in loud noise environments, without producing sharp noises like traditional backup alarms, thereby reducing listener fatigue and discomfort.
