Honeywell Silent Knight SKE-450 Voice Evacuation System


The SKE-Series Voice Evacuation system provides 50 watts of output power. The SKE-Series system consists of several different models, the SKE-450, SKE-450-ZN4 or SKE-450-ZN6. Each model has a built in Digital Message Repeater, power supply and a supervised microphone. All 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.
