When issues crop up, raise the alarm with this siren from Eaton. By ringing at sound levels up to 95dB, it makes itself heard over loud workplace noise to grab everyone's attention. Thanks to its built-in solenoid, the device responds to electrical signals as soon as a fault appears to support speedy signalling. A simple snap-together design means the sounder assembles in a flash, so you can skip through preparation. Its compact 155mm diameter ensures it easily fits into busy systems and makes it easy to find a suitable spot for it. Look for sirens like this used in processing plants and packaging facilities.
