Intrinsically Safe Alarm Beacons

Selection notes:

Select alarm beacons based on the nature of the alarm, the beacons direct visibility to personnel, the area covered, the beacon's physical size and material, the preferred method of protection (Intrinsic Safety or Flameproof) and of course, the certification requirements of the area where the beacon will be located. Consideration should also be given to whether a person could have their back turned to the beacon and the reflectivity of the surrounding area. In cases where the alarm is of utmost importance e.g. emergency evacuation, the EExd Rotating Mirror models have the highest chance of visibility.  For lesser alarms, selection can be based on the lamp power of the beacon and in confined areas, the outputs up to 6 Joules are normally adequate.

These intrinsically safe beacons are suitable for local alarm operation, where line-of sight will normally be achieved. The BA 386 is ideal for mounting over a control panel and may be used in combination with a BA385 sounder on the same I.S. circuit and offering the option of an alarm accept pushbutton to silence the sounder. 

An alarm condition can always be further signalled by using an Alarm Sounder/Siren Combination Unit as found on this website. They are normally driven from the safe area by using a Digital Output Barrier. If further assistance is needed, please contact us.
