5.2 SILENCING THE INTERNAL SOUNDER
5.2.1 FUNCTION
Pressing any key will silence the internal sounder, ie, cancel the pulsing alarm tone,
steady fault tone, or rapid pulsing test fail tone.
Note that the key pressed will still be processed as if the sounder was not on. Therefore,
it is safest to use the "CLEAR ESC" key to silence the sounder and not to use the "ACK"
key for faults or other states which are not automatically displayed.
Note: The alarm bells are silenced by the "BELLS ISOL" key.
5.2.2 OPERATING SEQUENCE
Press "CLEAR ESC" 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 ESC" key will, in addition to silencing
the buzzer, either step back through the menu or clear any number entry sequence that
has been started.
If all zone alarms are acknowledged, pressing the "CLEAR ESC" key will result in the
LCD exiting FFCIF mode. It can be re-entered with the Recall Alarms list command by
pressing the "RECALL" key when the base display is showing and selecting option 1 :
Alarms list.
