2.2.3. Remote Panels, Printers
Depending on how your system is set up, you may receive information from other types of devices other than the
AUTOCALL TFX-500M/800M control panel. These are Remote Ops/Dis Panels, Annunciator Panels, and Printers.
Remote Ops/Dis Panels
A Remote Ops/Dis panel allows the AUTOCALL TFX-500M/800M control panel to be operated from a remote location.
The front panel of the Remote Ops/Dis panel is identical to that of the AUTOCALL TFX-500M/800M (see Figure 1.2 or
1.3). It shows the state of the system and all AUTOCALL TFX-500M/800M functions may be performed at the Remote
Ops/Dis panel. However, only one operator at a time may have access to the AUTOCALL TFX-500M/800M system.
Suppose an operator has gained access to AUTOCALL TFX-500/800 functions by entering a passcode at either the
AUTOCALL TFX-500M/800M control panel or a Remote Ops/Dis panel. A display message on all other system display
panels will appear:
Remote Lock
Access is denied to any other operator, except to view events. A brief description of the function being performed (at the
panel in use) is also displayed on the other panels.
Printers
The AUTOCALL TFX-500M/800M provides memory capacity for storage of data to be sent to the printer. Printer messages
are stored in priority order, then in order of occurrence. Alarms first, trouble and supervisory messages next. Printer
memory stores up to 590 messages. The AUTOCALL TFX-500M/800M supervises the printer for wiring continuity and
loss of power that would prevent it from responding to the AUTOCALL TFX-500M/800M a control panel.
2.3. Normal Operation
A powerful feature of the AUTOCALL TFX-500M/800M system is its flexibility. It allows an operator to isolate (disable)
parts of the fire control system. Because of this, access to panel functions is restricted (by passcode), to only those people
who are thoroughly trained and authorized.
