Audio Distribution Module Enables Fault-Tolerant Warning Systems

ADM4

Audio evacuation warning systems are vulnerable to short-circuits caused by overheated insulation. If heat from a fire melts the 100 Volt line insulation, the resulting short-circuit will silence every speaker on the shorted cable. People in the affected area may have no warning until it’s too late.

The Pertronic Audio Distribution Module (ADM-4) provides a highly effective solution. This new module splits the output from a single amplifier into multiple independently controlled and monitored 100 Volt audio channels. A system built with ADM-4 modules will keep going even if one or more channels develops a short-circuit. The defect monitoring works all the time, whether the ADM-4 is distributing audio or not.

Several ADM-4 modules may be connected in parallel to a single amplifier, providing four switchable audio channels per ADM-4.

A single ADM-4 can switch up to 80 Watts per channel, or a total of 250 Watts per module.

The ADM-4 is compatible with Pertronic evacuation amplifiers and any third-party amplifier that is controlled by a Pertronic Evacuation Generator (EVACGEN-EA).
