Installing your new Pulsar wall-mounted noise activated warning device is a task you can easily take on yourself.  This product will make a big difference in your workshop, warehouse, production line, factory, pub, school or even hospital. Whether this is a brand new device or an additional unit to be added to an existing Pulsar noise warning system, you can install this product in just thirty minute.  By doing so, you will help control high noise levels and alert staff and visitors alike to take appropriate corrective action.

For the basics to help you get started, read our instructions below.

Setting the trigger level of your noise activated warning devices

First remove the back of the noise activated warning device with the screwdriver provided and select the trigger level. This can be anything from 40dB(A) to 114dB(A).  The sound level chosen for the trigger point can be set using the simple level selection. Please remember when setting the trigger level that this is the level at the microphone. The microphone is located at the back of the device.  Always adjust the level to take account of any distance between the microphone and noise source.

Follow the diagram below:

Fixing the device on the wall – what you will need:

To complete this project, you will need to use the supplies provided in the box with the PulsarSafeEar:

  • Screwdriver
  • Wall mounting screws (x2) and wall plugs (x2)
  • 5m extension cable
  • Microphone
  • Power Supply
  • Wall mounting template

PulsarSafeEar microphone connectFor the noise warning device to wake and illuminate its warning message, you will need to connect the microphone and power. Screw in the microphone at the back of the unit.  Use the cable supplies provided in the box and connect as shown on the diagram.

When the noise level measured by the microphone reaches the trigger level selected, the sign will illuminate and flash the warning.

Please note this device can be set to keep the warning illuminated for up to 30 seconds after the level has fallen back below the trigger level. This removes the sudden on-off indication that traditional noise warning signs often produce. This, in turn, eliminates confusion as to when hearing protection (PPE) should be worn.

Checking the device is working properly

The last step is to check that the installation of your noise activated warning devices has been successful. Clap your hands a few times in front of the device to check that the warning icon and message illuminate satisfactorily.  Stop clapping to check that the warning and safety icon disappear.
