CONTROL OF FIP BY MULTIPLE OPERATORS
For a standalone F4000 FIP, only one operator can have control over the FIP as there is
only one operator interface (the keyboard and LCD).
When an F4000 FIP is connected to:
- RZDUs
- RDUs
- Colour Graphics Displays
- Remote operator via the programming terminal, or
- Other panels via the Panel-Link network,
there may be more than one operator controlling the FIP. Ie. multiple operators could be
trying to reset, isolate, test, etc, the zones or other controllable items at the same time.
Depending on the system programming, alarms in the FFCIF alarm list may be
acknowledged, reset or isolated, from any of the operator interface points.
Thus alarms in the FFCIF list may disappear from the LCD because another operator has
reset the zones in alarm from, for example, a colour graphics system.
Also, the internal sounder may silence as a result of receiving and/or actioning a remote
operator’s command.
As of V2.35, the single keypad and LCD interface can be operated simultaneously by up to 3
users at a time:
•
An operator physically at the FIP keypad/LCD.
•
A remote operator connected via the programming terminal.
•
A remote operator connected via the Panel-link network.
The physical LCD display will change in response to the actions of the remote operator.
