ii) FP LINK FAULT
a) Where an open, short or high resistance connection occurs within the FP LINK cable,
the status display will show “FP LINK FAULT”, the yellow fault LED will light and the
sounder will beep every second. This condition will remain until the fault clears.
b) An “Other Fault” message will be transmitted, which may be received by a suitably
programmed pager or group of pagers if required (must be specified at time of ordering).
Note: whilst the FP LINK FAULT input is active, “TX IN SERVICE” transmissions to
the pagers are suppressed. If the FP LINK FAULT condition remains for more than
two minutes, the pagers will display “NO SERVICE” until the fault condition is
cleared (whereupon the TX IN SERVICE transmissions will resume). This acts as an
additional safety feature to ensure that all users of the system are aware of the fact
that the link to the host fire alarm system is faulty or inoperative.
c) The Common Fault output to the host Fire Alarm panel will change to the closed state
(normally open relay contact).
iii) ANTENNA MISMATCH
a) A missing or shorted antenna will be indicated on the status display within one hundred
seconds of its occurrence as “ANTENNA MISMATCH”, the yellow fault LED will light and
the sounder will beep every second. This condition will remain until the fault clears.
b) The Common Fault output to the host Fire Alarm panel (normally open relay contact)
will change to the closed state where the fault condition remains for at least 10 successive
test calls (using the default 50 second test call period = 500 seconds). This prevents
nuisance call outs due to momentary fluctuations as a result of birds, vehicles, etc being in
temporary proximity to the antenna.
c) Similarly, after the nuisance wait period, the system will still attempt to transmit an
“Other Fault” message, which may be received by a suitably programmed pager or group
of pagers if required (must be specified at time of ordering).
iv) TRANSMIT FAULT
a) A fault on the transmitter evidenced by either excessively high or low current draw will
be indicated within one minute of its occurrence on the status display as “TRANSMIT
FAULT”, the yellow fault LED will light and the sounder will beep every second. This
condition will remain until the fault clears.
b) The system will still attempt to transmit an “Other Fault” message, which may be
received by a suitably programmed pager or group of pagers if required (must be specified
at time of ordering).
c) The Common Fault output to the host Fire Alarm panel (normally open relay contact) will
change to the closed state.
