The SKE-450 and SKE-450-ZN4/ZN6 voice evacuation are activated when one of the two alarm inputs are tripped. When this occurs the control will output a pre-recorded audio message corresponding to the alarm input that was tripped. The repetition of the digital audio message and the selected notification output are completely programmable. The SKE-450-ZN4/ZN6 comes equipped with a 4 or 6 zone splitter respectively, capable of dividing the speaker output from the amplifier into four or six Class B or Class A outputs. The zone splitter also has an All Call feature that will activate all speaker zones regardless of the individual toggle switch settings.
