Combination units are designed to provide audio and visual awareness to an emergency situation. Units are suitable for use in the harsh environmental conditions found offshore and onshore in the oil, gas and petrochemical industries. Combination units can be wired for simultaneous operation or individual operation.

Pneumatic horns are used wherever extremely loud signals are required and there is no power supply available. One possible application is in railway track construction to warn personnel of approaching trains. Since the signal has to travel long distances, the maximum volume of the PH 1 pneumatic horn of approximately 135 dB(A) is needed here.

Designed to not only meet the most stringent Life Safety requirements, but also provide you with industry-leading intelligible voice communications for Wide-Area Mass Notification.
