Let’s go!!!
Nice! I love that Lithonia HQM and that Presco-Lite Novus
Love the video
he got the HQM!!!
Welcome back
I am actually surprised that you have not refered to the jieming sign as a starbucks. Black housing is really starting to grow on me and your prescolite novus looks amazing.
Cool to see you back making videos
I like how the last one has a light on the bottom
Very cool!
I'd like to know what the code says about emergency lightning in your area?
Here is a condensed rule since the 70' in France
-Safety lightening may be achieved with centralised power or self-powered fixture
Centralized is barely only use in malls as you have to maintain some light over a huge place.
All fixtures in a building are wired to a remote control that allow you to switch them on/off no matter of the presence of power.
On for testing purpose, off, if you intentionally cut the power in order to keep the battery charged (main use is during electrical work)
They must run at least One hour for "general purpose" and up to 6 for the specific ones you have to use in underground place like parking lots.
Brand new the batterie last more than 2 hour that give you a comfortable headroom for ageing.
You were supposed to run a monthly test to check if the batterie is still OK and have to replace batterie if under one hour (or 6) and also check if the permanent light is not burnt.
As the test was not perform monthly in most of installation (even if ever) the maker started to implement some self-test that finally became mandatory and unified in 2011.
You set the time of test on each block (just press the test button 10-20 sec to instruct do the test now) and the bloc will perform a discharge test at this hour randomly over a 21-30 days at first then 30 day in order to avoid all the fixture to be in test the same day) you must set this at the morning to allow test then batterie reload before night
All fixture now also come with a daily self-test for lamps (switch on 10 second checked by photocell), and a monthly discharge test. Status is reported by green led and amber one that flash differently for battery and lamp failure.
As there is wire for remote (positive 9V burst for on negative for off) they now add data bus to the remote line.
This way all fixtures are monitored by a central point, each one is addressed with a unique number.
So just like many things today, they can be “connected”, this is used to monitor remotely this way the company in charge of maintenance can come knowing what they need to bring with them.
This also allow a fine tuning of testing, let’s say for a school, you can set daily test at midnight to avoid alarming children with the light (yes, they can complain about this or teachers complain about the huge distraction it may cause), set the day like Saturday morning for test which allow 2 days before reopening and get fully charge
Or choose one by one pattern of test for 24/7 use like hospital.
You may even make a yearly test of full discharge to know the headroom, and decide to change all that are under one hour and 10 minutes as they will surely failed soon if it’s a place far away from your office.
Oops, it's a bit long but when you love things it seems you always go too far !
I was the first person ever to see this video
Nice video also i loved exit signs since i was 5 years old
Nice stuff! I like the Lithonia hqm!
This would have been a good opportunity to use a Lithiona ELM2 Gen 2
I have that emergency planned for a future episode. Stay tuned!
Nice!
Nice

Slight goofup on the LHQM, the one with the circular krypton halogen heads isthird generation. The difference between 1st and 2nd gen is that 1st gen had 3.6W incandescent bulbs fir emergency mode, but the second gen had an all LED exit, for both AC and emergency mode
The model shown in this video is the HQM, all incandescent combo unit. Its successor was the LHQM (first generation.) The combo looked identical to the HQM, but had LED exit letters, hence the prefix “L.” Years later they reintroduced the LHQM with a more modern design, and a thinner profile now with round krypton halogen emergency light heads. They also called it the LHQM so it became the second generation LHQM.
@@ExitSign250 another significant difference between the two LHQM variants that I consider 1st and 2nd gen is that 1st gen used tower LEDs while 2nd gen used the same piranha LEDs that the third gen used. I'm unsure if the second gen calls for a 4ah battery or if it still uses a 7ah like the first gen and HQM. note that these are my observations from how I identify generations and why I think that is correct, don't confuse yourself. not trying to say you're dumb or anything, just want to avoid confusion as much as I can.
@briggscarson I understand what you are saying. I consider generations as the unit as a whole, versus different internal components changing over its lifespan. In my opinion it gets harder to identify and makes it unnecessarily more complicated.
@@ExitSign250 I guess... I used to consider the 1994 edition of the Sure-Lites UN as second gen and the post 94 UNs as third gen even tho the only change was the faceplate style, so i guess the 1994 and post 94 UNs would be the same generation. Old habits die hard, and the round-head krypton halogen will probably always be third generation to me, but you make a good point.
I have a lithonia but the whole sign broke except the face plate LAUGH OUT LOUD
3rd
