Control Keys
Five CONTROL keys and their associated LEDs (Figure 33) are located on the far left of the operator interface panel.
Normally, these keys and LEDs are concealed by the access door. A custom label is used to identify the desired
function. Typical functions for these keys are city disconnect, manual evacuation, door holder bypass, start a drill,
control all signals, elevator capture, control air handling units, and manual control. When a control key is pressed,
the programmed event occurs.
