OPERATION

5.1 INDICATORS
The FV300 FlameVision detector has a red LED for reporting alarms and a yellow LED for
reporting faults. Both LEDs are located in the camera window, see Fig. 22. The alarm LED turns
on to report an alarm. The fault LED turns on to report hardware faults or is flashed to show an
OPM 'dirty window' fault.
The red LED will turn on briefly when an alarm test is performed.

5.2 POWER UP AND INITIALISATION
On power up, the detector performs a complete self-test to check all functions. The alarm (red) and
fault (yellow) LEDs flash briefly as power is applied. The alarm LED then turns off and the fault
LED remains on for the duration of the self-tests. If a fault is detected the LED remains on and the
fault signalled as below.
With the self-tests complete, the array is now allowed to warm-up and settle. During this time the
fault LED will flash rapidly (about 3 times per second). When the array is ready, the fault LED will
turn off. This will take about 5-20 minutes. If the array does not settle within 30 minutes then a
fault will be indicated and signalled.
Note: The detector cannot detect alarms, do OPM tests or alarm tests whilst the array
is settling.
5.3 ALARM AND PRE-ALARM INDICATION
The alarm (red) LED will illuminate when the detector is in alarm. It will remain illuminated until
the reason for the alarm has cleared (non-latching mode) when it will turn off. In latching mode
the detector will also need to be reset, see below.
The alarm (red) LED remains off when the detector enters the pre-alarm state.
The alarm LED is located in the camera window, see Fig. 22.
The remote LED output will be activated when the alarm LED is on to give an external alarm
indication.
