12.0 Performance
12.1
Sampling Rates
The FlameGard 5 MSIR Flame Detector samples each detector at 10 msec intervals.
12.2
Power-up
On power up, the FlameGard 5 MSIR Flame Detector executes a self-test procedure, which requires
approximately 15 seconds. During this time, the analog output is set to 3.5mA. After the self-test is satisfactorily
completed, the unit sets the PV to a value representing the mode of the instrument.
12.3
Device Reset
The FlameGard 5 MSIR Flame Detector cannot be reset by any command. The unit only resets when power is
cycled.
12.4
Self-Test
The FlameGard 5 MSIR Flame Detector goes through a self-test upon power cycle. Should any of the tests fail,
the unit immediately reports a fault condition.
12.5
Command Response Delay
The FlameGard 5 MSIR Flame Detector responds as follows:

Busy and Delayed-Response
The FlameGard 5 MSIR Flame Detector does not use delayed-response times.
12.7
Long Messages
The largest data field used by the FlameGard 5 MSIR Flame Detector is in response to Command 21: 34 bytes
including the two status bytes.
12.8
Non-Volatile Memory
The FlameGard 5 MSIR Flame Detector uses EEPROM to hold the device’s configuration parameters. New
data is written to this memory immediately on execution of a write command.
