Just discovered something huge today! I recently got my hands on two of the new System Sensor LED L series horn strobes, and I decided to mess around with them today. After jittering the power in the right way, I was able to get one to go into temporal 4 CO mode. I also have a video of two doing it at the same time unsynchronized. I know a few have done this before, but I thought it was really cool. Here are some videos:
One Device: here
Two Devices: here
Neither video can be watched as Google Drive says “You need access”.
Links should be fixed now
Alright, good, & they are, so thanks. Something tells me that the white strobe together with the temporal 4 wouldn’t be considered legal though (heck why manufacturers are even trying to fit temporal 4 into horn/strobes when most of the time non-fire alerting like that would be handled by a voice/mass notification system & only a voice/mass notification system (because of their additional capabilities) I have no idea).
As far as I know, white strobes are fine for non-fire use, and I believe I even saw some standards that prohibit the use of amber strobes for MNS in some cases. The more obvious problem is the FIRE lettering, but that can be changed with a bezel.
Well last I heard I could have sworn that white strobe were limited solely for fire alarm use & nothing else by code.
What!? I don’t know why that would be the case when it’s the ideal color for non-fire emergencies! (which it’s basically been adopted as by now anyway)
Yeah.
NFPA 72 section 24.5.17.3 allows a single strobe to be used for both fire and MNS if it is clear/white, has no lettering or ALERT lettering, and is visible to the public.
I am probably misremembering, as I don’t know where I saw this. The requirement may have stated that amber strobes are prohibited if they are used for both fire and MNS (i.e. the requirement above).
Oh? Huh, alright…
Oh, okay, that makes sense I guess.
