Zone 0 signalling

The IS-D105 sounder and IS-DL105 combination device are approved to IECEx and ATEX standards for Zone 0 and the IP66 sealed marine grade aluminium enclosure is phosphated and powder coated, offering enhanced protection for on and offshore applications.

The powerful alarm horn produces up to 105 dB(A) at 1 metre with a choice of 49 alarm tones and 2 additional, remotely selectable, alarm stages. For specific applications, custom tone configurations and frequencies can be engineered. The sounder can be combined with an LED beacon featuring an array of 6 high-intensity LEDs.
