Audible Warning Signals

November 5, 2018

Your bedside alarm clock may be far from your best friend, but it serves a purpose – to wake you up. This is a very simple example of an audible signal – audible warning signals and audible alarms are on a completely different scale, which is why it’s important to know the different types of audible warning signals available.

Types of Audible Warning Signals

Audible warning signals are available in various forms:

  1. Air horns
  2. Electronic Sounders
  3. Bells
  4. Hooters
  5. Buzzers
  6. Sirens

 

Sound Level and Frequency Rating

The sound level of an Audible Alarm depends upon the decision of the designer. Sound level is the amplitude of air pressure produced by the alarm. Moreover, frequency rating is also an important characteristic to consider in audible alarms. In music, frequency rating is known to be the pitch. It is the number of pressure variations per seconds measured in Hz.

Power Consumption

Power consumption has become an important issue when it comes to product design. Audible alarms need around ten mA to more than 80 mA in order for it to operate.

Quality of Construction

Of course, never forsake the quality of an audible alarm. In order to get the most effective alarm, check its construction.

Quality Testing

This audible alarm basic is important to guarantee that an audible alarm is really suitable. This can include the testing of the surge voltage, reverse voltage, water spray (IP Rating), shock / vibration, and so on.
