Model FL4000H
NOTE:
If the user writes to this register, it overrides the value set by bits 2 and 3 of register 8.
Reading register 8 will simply return the last values in bits 2 and 3 that will not show the
value written to this register. This behavior is intentional and is to provide backward
compatibility with other General Monitors’ flame detectors.
4.10.40 Power Cycle Flag (0x009A)
This reads whether the time of day clock has been reset after a power has been re-cycled to
the unit. If the time has been reset, this flag will be = 0; otherwise the flag will = 1.
4.10.41 Event Index (0x00A0)
This is used to indicate which of the stored events the user would like to read. There are 4
event logs maintained by the FL4000H unit: Warning events, Alarm events, Fault events, and
Maintenance events. Each of these event logs consist of 10 of their most recent occurrences.
The user is able to read the times of each of these by setting this event index followed by a
reading of the desired event log. The event index is a number from 0 to 9. Zero refers to the
most recent event and 9 refers to the least recent event stored in the log. For example to read
the most recent Warning event in the Warning event log, set this register to 0 and then read
registers 0xA1 and 0xA2 (for the running time in seconds) or read registers 0xA3, 0xA4, and
0xA5 (for the clock time). There is also a warning counter which gives the total number of
warnings received by the system (with a maximum of 65535).
4.10.42 Warning Running Time in Seconds, Hi Word (0x00A1)
This register reads the hi word of the running time in seconds when the warning event
occurred. This time is in seconds since January 1, 2000. This register should be read before
register 0xA2.
4.10.43 Warning Running Time in Seconds, Low Word (0x00A2)
This register reads the low word of the running time in seconds when the warning event
occurred. This time is in seconds since January 1, 2000. This register should be read only after
register 0xA1.

Register Description
1 A3 Hi Byte =Year, Low Byte = Month
2 A4 Hi Byte = Day, Low Byte = Hour
3 A5 Hi Byte = Minute, Low Byte = Second
The values from the above table should be read in order: first item 1, then item 2, & then item 3.
4.10.44 Warning Clock Time: Year, Month (0x00A3)
These registers are described in Table 35 item number 1.
