The D1xC1X05R is a globally approved high output 115dB(A) alarm horn with omni-directional radial horn a & 5 Joule Xenon strobe. The robust Type 4/4X, IP66 marine grade, corrosion proof LM6 enclosure ensures suitability for all Class I/II Div 1, Zone 1/20 and , IECEx/ATEX Zone 1/2 applications.



The explosion proof horn strobe allows simultaneous or independent operation. Featuring 64 first stage/channel alarm sounds, the alarm tone frequencies for the first 2 stages are independently selectable. Each of the 4 stage/channels can be remotely triggered e.g. via an external relay. The Class I DC version is approved for public mode fire alarm use (alarm horn) and private mode fire alarm use (strobe beacon).
