7 Acquisition of panel operation data • • • [QS2]
The command QS2 is for acquiring data on the panel's operations. Basically, this command is used for the module's
A
microcomputer to inform the main unit's microcomputer of changes in panel operation.

• If no power-down is generated, 00 is transmitted. If a power-down is generated, data on power-down points are transmitted, with upper-
level point as 1st PD and lower-level point as 2nd PD.
• The TEMP1 input value (10 bits) is transmitted in 3 bytes in decimal notation (range: 000-999) as temperature data.
Values of 1000-1023 are handled as 999. (During Standby mode, the value retained in RAM is transmitted.)
• As to data on the hour-meter count, minute data (3 bytes) stored in the EEPROM are converted to hour data and described in 6 characters.
F
These 6 characters and 2 characters representing minute are transmitted. The maximum recording time is 279,620 hours 16 minutes.
