Side Alert System with Speed Pulse Module Kit

The SA-US4-SC Side Alert system from EchoMaster helps reduce risk and minimises both collisions and damage by alerting drivers of large vehicles to obstacles such as cyclists or pedestrians within the vehicle blind spots, whether stationary or manoeuvring at low speeds.

The SA-US4-GPS system consists of 4 daisy-chained heavy-duty sensors that can be flush mounted to the vehicle, or underslung when used with the metal brackets provided and a SpeedPulse Module.

The SPG-GPS-GPS uses GPS technology to generate two road speed dependant outputs. The first output pulses at a frequency proportional to road speed. The second output changes state when a pre-set road speed is exceeded. The interface is easy to install and utilises a built-in antenna. It is suitable for 12v and 24v vehicle electrical systems.
