Pulsar SafeEar Noise Activated Warning Sign


  Lights up when a pre-set noise level is exceeded
  Quick and simple to install
  Trigger level from 40dB(A) to 114dB(A)
  Suitable for both quiet and noisy environments
  Adjustable, high intensity white LED technology for high visual impact and a long operating life
  4 standard designs to cover all applications

Suitable for both noisy and quiet environments:

The PulsarSafeEar is perfect for use in factories, workshops, pubs and nightclubs to warn when noise levels become too high and indicate when hearing protection must be worn. In environments where the wearing of hearing protection (PPE) may not be required at all times, the PulsarSafeEar will inform employees when PPE is required and also when it can be removed safely.

PulsarSafeEar can also be used in quiet locations such as schools, hospitals and libraries to indicate when noise levels must be kept down. By setting the PulsarSafeEar to trigger at a lower level ensures that noise levels in quiet environments stay within acceptable levels.

Installation & Use

Installation of the PulsarSafeEar is very simple. Select the trigger level and connect the power supply to the unit. When the noise level measured by the microphone reaches this level, the sign will illuminate and show the warning.

The unit can also 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. The PulsarSafeEar eliminates confusion as to when hearing protection (PPE) should be worn.

The sound level chosen for the trigger point can be set using the simple level selection at the back of the unit.

Remote Display Units

The PulsarSafeEar is also available as a Remote Display Unit which is controlled by a Master PulsarSafeEar Unit. A simple cable from the Master to up to 3 remote units can be daisychained together so that an area of up to 30 metres can be covered.

Record & Store with PulsarSafeEar Data Logging Software

The PulsarSafeEar can be upgraded to become a data logging unit by adding the PulsarSafeEar Data Logger and USB Software. The Data Logger simply plugs into the PulsarSafeEar and can record noise levels over long periods of time. The Data Logger can be programmed to start recording at a specific time and date and run, for example, over an 8 hour shift.

When the Data Logger is plugged into a PC the software will display a graph of the recorded noise levels and allow the data to be printed, exported and annotated for reference.
