Intrinsically Safe Sounders

Selection Notes:

Select and set tones on alarm sounders/sirens based on the nature of the alarm, the area covered and the background noise levels, the preferred method of protection (Intrinsic Safety or Flameproof) and of course, the certification requirements of the area where the sounder will be located. In cases where the alarm is of utmost importance e.g. emergency evacuation, consideration should be given to the fact that background noise levels are often much higher during an emergency than under normal conditions.

All sounders shown are manufactured in GRP. Stainless Steel and Marine Grade Alloy models also available. They are normally driven from the safe area by using a Digital Output Barrier. If further assistance is needed, please contact us.
