Plena Voice Alarm System
Power requirements
The system controller features a built-in 240 W power amplifier, able to drive up to 40
loudspeakers (6 W). Additional Plena Power Amplifiers are incorporated to provide additional
power, two-channel operation and spare amplification. To facilitate phased evacuation from
different floors of the hotel, guest areas are divided into separate zones, each fitted with 13
ceiling loudspeakers in the corridors. The bar uses cabinet loudspeakers, while the parking
garage uses weatherproof horn loudspeakers.
