2.4 AUDIBLE
TONES
Any requirement for operator intervention is signalled by the sounding of the FIP's internal
buzzer. The buzzer can be activated in a number of different modes, each of which gives
some indication as to the type of event that has occurred. The internal sounder provides the
following audible tones in order of decreasing priority (see note below):
(a)
ZONE / SYSTEM FAULT
-
Steady Tone
A continuous tone indicates that an un-isolated zone has gone into FAULT, or a system fault
has been detected. Note that the Zone Fault buzzer can be disabled by programming, and
for V2.31(N) or later FIPs the zone/system fault tone can be made to be of lower priority than
the zone alarm tone.
(b)
KEYPAD "INPUT ERROR" -
Long single beep
(c)
KEYPAD "KEY ACCEPT"
-
Short single beep
(d)
ZONE ALARM
-
Two Beeps per Second
A regular, two beeps per second tone, indicates that an un-isolated MAF mapped zone has
gone into ALARM. Note that the Zone Alarm buzzer can be programmed to be disabled, or
made the highest priority tone (V2.31(N) or later).
(e)
TEST FAIL
-
Fast Pulsing Beeps
A 4 fast beeps then pause tone indicates that a zone, system, or power-up test has failed.
(f)
PANEL FAULT / DOOR INTERLOCK
-
Slow Beeping
A long beep followed by a pause tone. This can indicate specific types of panel faults,
please call service. If the FIP is not able to process alarms, if certain tests are operating or
links are in incorrect positions, the buzzer will sound in this manner if the door is closed.
Pressing any keypad key will automatically silence the buzzer.
