## Description

Product Description The Dolphin DMS400 is a 4 recess mounting sensor system manufactured to fit a wide range of cars and look like original fit equipment. This kit has 4 micro sensors with a buzzer. The buzzer gives audible bleeps with increasing frequency as you get closer to an obstacle. The unit is activated when reverse gear is selected. When the vehicle is less than 1.5 metres from the obstruction the audible alert will emit intermittent bleeps. As the vehicle gets closer to the obstruction the frequency of the bleeps increases. At 30 centimetres from the obstruction the bleeps become a continuous solid tone, warning you that you should stop the car. The sensors are on cables just over 2m long and should cover the width of most vehicles but we do have extension leads if needed. You mount the brainbox in the rear of the car, traditionally in a side panel behind one of the rear light clusters, so the sensor cables do not have to run to the front of the car. You connect the brainbox up to the reversing light for its power supply. The buzzer is on a 2m cable length designed to be mounted in the boot area. Available in 32 Colours There are 9 coloured sensors in the range, the colours are baked on so will not crack as can happen with retro spraying. The sensors require a 18.2mm hole (cutter supplied in box) and have a 20mm outerface leaving a 1.8mm overlap. Adjustable Brainbox Our new adjustable brainbox means that you have full control over the detecting distance that your parking sensors have from your car. This is particularly useful for cars with low bumpers or bumpers that are angled at the ground. It is not normally necessary to play with this setting but gives some flexibility with fitting if needed. Swap Socket Feature The kit has a watertight swap socket feature based 6 inches from the sensor heads, it makes installation quicker and easier. Also should you ever have a problem with faulty sensors or accident damage in the future it facilitates easy replacement without having to rewire from scratch.

Review: Great product and easy to fit. - Great product. I have bought three of these kits now and very happy with the performance. Very clear instructions supplied. Cable length for the sensors was easily sufficient. I find the reversing sensor is a bit to loud for my preference, so I simply applied a bit of tape over a few of the sensor buzzer holes. Although not cheap, it is a very good product and worth the money. The only important job to do is to accurately / symmetrically mark out the holes in your bumper prior to cutting the holes. I used masking tape to mark out all the positions.
