The SKE-Series Voice Evacuation system provides 50 watts of output power. The SKE-Series system consists of two different models, the SKE-450 and SKE-450-ZN4. Each model has a built in Digital Message Repeater, power supply and a supervised microphone. Both models have two alarm inputs, one triggered by reverse polarity and one by supervised dry contact trigger. The system supports 25 or 70.7 VRMS operation to accommodate most installations. The audio messages are field programmable via the built in microphone, through the line level input, or by downloading via the internet. The model SKE-450-ZN4 also contains a zone splitter capable of dividing the speaker output into 4 separate outputs.
You will need to download and install the 7780 application. This application allows you to program the downloaded voice messages into the SKE-450.
This application is available on the Silent Knight web site.
