The Elemec plus system is available in four basic configurations:
Single-sided - A single-sided system comprising of one set of “head end” equipment to control the system. Speakers are then connected to amplifiers as required.

Hot standby single-sided: A single sided system with a “hot standby” amplifier that is automatically substituted for a damaged amplifier.

Redundant: The redundant ABS style system includes two system controllers, usually referred to as “A” and “B”, that are linked via an RS485 interface. These units are in continuous communication and if one unit is damaged or taken out of service, the other unit will automatically control all amplifiers. The system speakers are divided equally between the two controllers.

Duplicated - For the maximum level of safety, we offer a DNV style duplicated system. Typically, this includes two totally redundant head-end controllers and amplifiers in separate cabinets at different locations. In this configuration, two completely separate and overlapping speaker systems are required, meaning that each area of the facility would have speakers powered by each of the two systems. Should a speaker line be damaged then the second speaker will continue to operate maintaining full coverage.
