General Operating Instructions
Operation
The Cornell 4800 Rescue Assistance System provides both audible and visual indications of Emergency calls.
Normal system function indicators include a steady red “Main Power” Led and a (10) second supervisory LED
pulse at all of the call stations.
General
Momentarily depressing the push button on a 4800V Call Station causes a short acknowledge tone and steady
call LED illumination at the 4800V Call Station. The 4800V Call Station LED begins flashing when the pre-
recorded “Pending” message is announced. At the Control Panel(s), the location of the 4800V Call Station(s) is
displayed in order of activation. Whenever there is one or more calls placed that have not been answered, a
slow repeating audible alarm is sounded at the Control Panel(s), and the “Action Required” LED will be flashing.
Selecting an “Active” 4800V Call Station will connect 2-way voice communication between the Control Panel(s)
handset and the 4800V Call Station. The Control Panel(s) operator will immediately be connected to listen/talk
to the person at the 4800V Call Station. Momentarily depressing the “Select Top Row” button again will
disconnect voice communication to the 4800V Call Station and complete the call.
Any Control Panel may respond to an incoming call. However, once a call has been “Connected” via the modem,
the remaining Control Panel(s) will indicate that the call has been “Answered”, and will not be able to connect to
that location.
Voice communication can be re-connected to any active 4800V Call Station shown on the display list, by pressing
the Up/Down arrow keys, to scroll the location to the top line of the display and pressing the “Select Top Row”
button. To cancel communication, press the “Select Top Row” button again. To clear all previous calls, press the
“Clear All Calls” button twice, at the Main Control Panel. The “Clear All Calls” function only functions from the
Control Panel designated as the “Main Control Panel” in the system.
