Powering Up The Flame Detector; Testing The Flame Detector - Dräger Flame Serie Instrucciones De Uso

en Use
Possible heated optics settings
The heated mode can be set to one of the following:
OFF: Detector window is not heated

ON: Detector window is continuously heated

Automatic (default):

You can define the start temperature below which the detector
window is heated. The default is 5 °C (41 °F). The start
temperature can be defined between 0 °C (32 °F) and 30 °C
(86 °F). The heating stops when the temperature is 15 °C (approx.
27 °F) above the start temperature.

Powering up the flame detector

1. Power up the system.
2. Wait approximately 60 seconds for the flame detector to finish the
start-up procedure.
The startup procedure is as follows:
The status LED flashes yellow at 4 Hz.

A BIT is executed.

If the test was successful:
The status LED flashes green at 1 Hz.

The fault relay contacts close.

The 0-20 mA output is 4 mA.

Testing the flame detector

1. Disconnect or disable external devices, such as automatic
extinguishing systems.
2. Make sure that the status LED flashes green.
3. Perform one of the following tests:
Manual BIT (Dräger Flame 2100/2350 only, see page 16)

Test using the Dräger FS 1200 flame simulator (see page 17)

4. Connect or enable external devices, such as automatic
extinguishing systems.

Manual BIT (Dräger Flame 2100/2350)
NOTICE
If the functions alarm BIT and/or auxiliary BIT are set to YES, alarm
relay, auxiliary relay, and 0-20 mA output are activated during a
manual BIT.
► Disconnect automatic extinguishing systems or any external
devices that may be activated during the test so that no fire
extinguishing measures are initiated.
To perform a manual BIT:
Momentarily connect terminal 3 with terminal 2 or switch across

these terminals in the safe area.
If the status LED flashes green at 1 Hz, the test was successful.
If the status LED flashes yellow at 4 Hz, the test was not
successful.
If the BIT was not successful, it is then automatically performed
every minute. This continues, until a successful BIT occurs and the
flame detector resumes normal operation. The fault indication
remains until power is disconnected from the flame detector. The
fault indication returns if the fault is still found when power is
restored.
