General Operating Instructions Cont.
Modem Operation
The 4800 Digital Emergency Communication System incorporates a programmable automatic dial feature to
connect to an
Analog “POTS” dedicated telephone line. In the event that an incoming call is not answered, at
any of the Control Panels in a preset amount of time, the 4800 system will dial a pre-programmed phone
number to directly connect the 4800V Call Station to a monitoring location.
Optionally, a pre-recorded voice message can be played, when the Modem is connected to a monitoring
location. The message should identify the specific building location. Additionally the specific call station
location can be provided.
The “Monitoring” connection can be terminated by scrolling the “Connected” call to the top row of the display
and pressing the “Select Top Row” button or by pressing the “Mute Alarm” button. Either action will
immediately terminate the phone conversation and connect a voice path from the Control Panel(s) to the 4800V
Call Station.
System Faults
The modem/phone line circuit integrity is checked every 24 hours. In the event of a failure, a “Fault” notification
will appear on the Control Panel(s) display. System faults produce an audible signal at the Control Panel(s), a
flashing “Action Required” LED and are indicated on the display(s).
Optionally, in the event that a fault is not corrected, in a preset amount of time, the 4800 system will dial a pre-
programmed phone number to report the fault to a monitoring location. This will be in the form of a pre-
recorded voice message providing specific building location and a brief fault description.
PLEASE NOTE: The pre-
recorded system fault message will play automatically. Consult your local “Authority Having Jurisdiction” and
the monitoring location to see if this is acceptable.
