Intelligent 50 Watt Amplifier


The TR-50W (red cabinet) is intelligent 50 watt amplifiers for use with the TR-2100ECSR /TR-2100ECSB. The TR-50W is used to amplify the audio message for distribution throughout the facility. Since it is designed as a self-contained distributed amplifier it can be conveniently located near the area of protection to reduce wiring demands. The TR-50W is capable of producing 50-watts of audio power. Up to eight TR-50W’s can be used on the voice evacuation system. The TR-50W has its own power supply with battery backup and four speaker circuits which can be expanded to eight speaker circuits with the optional TR-CE4. The TR-50W is fully supervised by the main panel for trouble conditions.


The TR-50W is compatible with the following Triga Series voice evacuation components: R-2100ECSR /TR-2100ECSB.
