10.2.10 PANEL RESET Sentence Structure 
This message is sent when the panel is reset from the fire alarm or fault condition. 
Since this is not a fire or fault alarm condition, it uses the EVENT formatter EVE (general event messages are 
used to output detailed information about events in a safety related system in a format that can be stored but not 
necessarily understood by the VDR). 
 
The message takes the following form: 
$ttfff,hhmmss.ss,a—a,c—c*hh<CR><LF> 
$ – start of sentence 
tt – Talker Identifier = FR (Fire detection system) 
fff – Sentence Formatter = EVE (EVENT) 
, – Field Separator 
hhmmss.ss – Time of event = VDROB has no clock so set to 000000 
a—a – Tag code used for identification of source of event if applicable. 
c—c – Event description text = PANEL 01 RESET OPERATED 
* – Indicates next two characters are the checksum 
hh – Checksum (XOR of all bytes including commas but excluding $ and *) 
<CR> – Carriage Return character = HEX 0D 
<LF> – Line Feed character = HEX 0A 
 
The RESET sentence is: 
$FREVE,000000,Panel01,PANEL 01 RESET OPERATED*07<CR><LF> 
The HEX data is: 
24 46 52 45 56 45 2C 30 30 30 30 30 30 2C 50 61 6E 65 6C 30 31 2C 50 41 4E 45
