4.10.32
COM2 Data Format (0x0031)
A read returns the COM2 data format of the FL4000. A write changes the data format to the
requested format. After changing the data format of the FL4000, it will be necessary for the
controlling or master device to similarly change its own data format in order to once again
communicate with the FL4000.
NOTE:
By grounding the RESET input during the power-up cycle (approximately 10 seconds),
the data format of the FL4000 will default to 8-N-1. Valid settings are shown in Table 33.
4.10.33 Set/Read
Real-time
Clock Year, Month (0x0047)
This is used to read/write the real time clock. The high byte will be the year minus 2000. The
low byte will be a value from 1 to 12.
4.10.34 Set/Read
Real-time
Clock Day, Hour (0x0048)
This is used to read/write the real time clock. The high byte will be the day of the month from 1
to 31. The low byte will be the hour from 0 to 23.
4.10.35 Set/Read
Real-time
Clock Minute, Second (0x0049)
This is used to read/write the real time clock. The high byte will be the minute from 0 to 59 and
the low byte will be the seconds from 0 to 59.
NOTE:
The registers when read, should be read in order: first 47, then 48, then 49. When
written, they should be written in order: first 47, then 48, and finally 49.
4.10.36
Set/Reset TEST LAMP Test Mode (0x005A)
This is used to place the unit into Test Lamp test mode or return it to the normal mode. Writing
a 1 to the register places the unit into test mode. Writing a 0 to the register places it back into
normal mode. Refer to Section 3.6.6 Test Mode Terminal.
4.10.37
TEST LAMP Alarm Delay (0x005B)
Using the dipswitches, the alarm delay may be set to one of four pre-programmed settings (0,
8, 10, or 14 seconds). Register 0x5B is used to set the alarm delay to any desired value from 0
to 30 seconds. The dipswitch override flag must be set to 1.
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.
4.10.38
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.
4.10.39
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 FL4000 unit: Warning events, Alarm events, Fault events, and
Maintenance events. Each of these event logs consist of 10 of their most recent occurrences.
