5.1.3 FFCIF TYPE 2 OPERATION
When the FIP has been programmed for FFCIF Type 2 mode, the LCD displays a message
that indicates the global operations that can be performed. Pressing the ACK, RESET or
ISOL keys will silence, reset and isolate respectively, all un-isolated zones in alarm
(irrespective of their acknowledgement status).
The FIP still maintains a list of alarms as for FFCIF Type 3 operation, and these can be
viewed by pressing the RECALL key. The LCD then operates in FFCIF Type 3 mode, i.e. it
allows individual acknowledgement, reset or isolation of alarms. Pressing the RECALL key
allows an operator to return to the FFCIF Type 2 mode of operation.
REMINDER:
In Type 2 operation, alarms do not have to be acknowledged before being
RESET or ISOLATED.
NOTE:
In Type 2 operation, pressing the ACK key will silence the buzzer and mark
all events in the FFCIF list as "ACKD", however, the zones will NOT be
silenced, i.e. any Alarm LEDs for the zones will remain flashing.
5.2 SILENCING
THE
INTERNAL SOUNDER
5.2.1 FUNCTION
In FF mode (displaying an alarm) pressing any key in the FF area (except the Brigade Test
key) or the Prev key will silence the alarm or fault sounder. Thus to silence the buzzer in FF
mode it is safest to use the NEXT or PREV keys, and use the opposite key to step back to
the original alarm if there are multiple alarms present.
If the panel is not in FF mode then pressing any key will silence the alarm, fault, or test fail
sounder.
Note: The alarm bells are separately silenced by the Bells Isolate key.
5.2.2 OPERATING
SEQUENCE
Press "CLEAR" key once.
- the internal sounder silences.
NOTE:
If a key sequence was being entered, it may be necessary to re-enter number information or
the last command, as the CLEAR key will, in addition to silencing the buzzer, either step
back through the menu or clear any number entry sequence that has started.
If all zone alarms are acknowledged, pressing the CLEAR key will result in the LCD exiting
FFCIF mode. It can be re-started by entering the Recall Alarm List command.
Any fault action text displayed as a result of the buzzer turning ON for a fault will be
automatically cleared by silencing the fault buzzer.
The sounder may also be silenced on receiving a remote operator command, depending on
the system programming and configuration.
