System Operation
To place a call, the person needing assistance pushes the button on the call station. The LED on the
call station will flash to inform the user that the call has been sent. The control panel will indicate the
incoming call with an audible alarm and a flashing LED. The LED will identify the specific area
requesting help.
The operator pushes the acknowledge button to silence the audible. The call LED will go from flashing to steady to inform the user that the request for help has been received. The LED will remain lit
until the control panel is reset. If additional calls are received, the new calls will resound the alarm
and the new request will be identified with a flashing LED. Intercom capability is not available on ST
systems.
