Holding UL's feet to the fire...burn test
Here are two simple videos that enable you to decide for yourself if UL has been compromised. Is UL truly credible or are they simply orchestrating a cover-up for their failures? Look at the facts below. You decide.
The first video stars a very common Honeywell Vista 20P control unit as the fire alarm system in primarily residential installations. The video: Link to Video - burn test
Here is a second burn test with the flagship DMP commercial fire panel: Link to Video 2 - DMP burn test
- Shows the actual standards so you can read them for yourself.
- Shows and describes the data-bus and the devices that connect to it.
- Shows a fire causing a catastrophic failure prohibited by these standards.
Now, after you have viewed the actual standards and the video, do you agree with UL’s official written statement on the issue?
UL Conclusion of December 11, 2019:
faults associated with attack of data circuits by fire or intrusion are not part of the current standards, UL985 and UL1023
Are short circuits and faults on the data-bus causing catastrophic failure really not part of the current standards as UL claims? What does the plain language of the standards actually mean? Does anybody actually care what it means, especially UL? Would the sleeping family of the system being protected by the fire alarm in the burn test care? Would you want this system protecting you and your sleeping family in your own home?
Perhaps it is time to find out….

5 年I received the following comment on this issue from Michael Wright, a subject matter expert from UL, "Very interesting...as a UL subject matter expert for UL1076 and UL 294, I find this very disturbing. Have you ever had a response from DMP about why this is so and what if anything they intend to do about it?"
