The NEW System Sensor L-Series! / Unboxing & Review 

It really seems like yesterday that the Advance made its debut...back in 2007. These L-series devices are really cool, a nice mix between the original "classic" design, and the easy to mount design of the Advance series. Additionally, I like the return of the horn AND piezo sounds, similar to the original. The new ring design and mountable colored lenses are really neat. Basically, it's a cool versatile design that can be used in just about any application. It will only be a matter of time before these invade most buildings. I'm excited to see my first one at some point, and I'll probably nab one at some point in the future. Admittedly, I really like the Advance design, and really like this design.

This is my favorite video by S.E.R Safety.

Very futuristic looking very nice By the way love your vids been a long time subscriber Love your vids keep up the great work

I like how the one that has the back box exposed looks like a System Sensor classic and the one with the back box inside the wall looks like a System Sensor Advanced but even though they are the L-Series of the advanced alarm

I've been out of the fire alarm game since RU-vid's transition out of channel design and such. It's nice to see they still evolve.

Nice! Your lucky to be the first collector to have one of those!

Cool! I realized that the smaller one has the system sensor classic design and the bigger one is more like a spec-advance™ Design

BOTH the narrow and wide versions can be flush mounted or surface mounted. The narrow model is available for just a single-gang box, whereas the wider alarm can be mounted to a single-gang or square electrical box. The purpose of the narrower alarm is for systems that have single-gang boxes (like where an EST Genesis was originally installed without a trim plate). This allows more systems to have notification appliances with a smaller footprint (becoming a trend in new systems).

Nice I love these and the classics! By far my favorite alarms. this is my favorite video.

My school’s fire alarm system is getting replaced. It used to have Simplex TrueAlerts/QuickAlerts and Simplex Single Action pull stations, but they are getting replaced with System Sensor L-Series and either Notifier or Firelite pull stations (idk which brand). They have yet to replace the panels, along with the other remaining Simplex alarms and pull stations. Also, the weatherproof devices are a SpectrAlert Advance and a 6 inch Potter bell. I have a feeling the Advance will just be replaced with another Advance, but idk what they are doing with the Potter bell yet. Also, the reason behind the system getting replaced is because the school got struck by lightning, which made the original fire alarm system no longer functional. We haven’t had a fire drill yet for that very reason.

This is my favorite video of yours I absolutely love L series

I got the P2RL. It’s an awesome alarm

Annnnnndddddd I want it. lol you have gotten so much better at editing!!! I love your videos!

Awesome! Not too surprised they used the same tone as the previous Advance series.

The style and the fact that there are narrow and wide versions are like a wink and a nod to the Space Age AV-32 and AV-34.

Also, I LOVE the new blue box.

These alarms are very cool. I like the design and the ability to easily change the strobe lens; that's a really good idea. Maybe they'll make an LED model in the future? Although I'm surprised at such the low current draw for a xenon strobe; certainly a first in that respect. I also like how they revived the 3000hz tone from the classic.

AMAZING!

Love it 😍

Temple 3 3k sounds like a smoke alarm 🚨😁❤️👍

I like the interchangeable strobe color and bracket plates!

They already have the L-series horn/strobes in the renovated cafeteria/dining hall at my college's Student Center (Notifier AFP-200 system) and in some stores at our local mall (Notifier NFS2-3030 system.) And my aunt's high-rise has the speaker/strobe version (another NFS2-3030 system, replacing a conventional Notifier system from the 90s with Wheelock MT4-24-WM horn/strobes.)

they do look really cool though. They are bringing back the spectralert classic design kind of:)

I really like the new alarms!

1:58 the thinner one can also be used in compact spaces. (for example in between a door and a wall)

Can't wait for the Low Frequency versions

I love this video,it is so interesting

i love how you can change the alarms

i love the design

Very good horn strobes (and video)!

Love the covers strobe l series’s

They look........ Interesting. Very original design.

So pretty much another Spectralert Advance you should do a comparison of both the L series and Spectralert Advance

Nice! I was wondering when they were going to release new alarms.

Awesome video! How did you get all of those alarms?

WOW........THAT IS SO COOL!!!

I was in a hotel in Utah and they had the L series of alarms (the flush mount version)

Its like spectralert advance and spectralert classic had a child

Wow! Awesome! Those are super cool!

We have the p2rl at my school. But there is only one of them. We have specter alert advances, wheelock as and ns, and the Edwards 892b

do they have a outdoor version or a strobe only or a horn only? where did you get them?

THATS SOOOOOOO COOL

How do you get these? Did you email them or did they reach out to you? Cool video, by the way!

I love it 😍

I’m getting a system Sensor CHSRL (l-series chime strobe) and will it sound different than the the spectralert advance chime strobes?

So cool!!!

This is super cool 👍😎😎👍

Do a demonstration on how would you wire a wheelock safe path 4 to the ms-9200udls.

My dad's office building suite was forced to upgrade to a whole new fire alarm system this year they got these horn strobes in each of the offices and than spectralert advances wall mount in the hallways and they synced well together couldn't tell the difference between the two

I have these l series in my apartment complex..horn strobe and horn only hooked to a silent knight ifp-100 addressable panel with sk photo smoke/heat detectors... they sound exactly like the regular p2r advance but louder lol

Nice!

cool! do you think that they will install these instead of the Spectralert Advance?i hope not.

I just got the SPSRL and the P2WL-LF!

The p2grl can be flushed mounted as well. The small one can be better with the small back boxes but as with the p2rl, it can also be on a small back box as well. But I seem to see the small one kinda useless

whats the model of the accesories you got for them. Like the colored strobes and trim plates.

That is awesome

That's A Cool Alarm

I love these fire alarm coding

Do you know the name of the strobe covers? (As in SpectrAlert PC2R.)

My local target used to have regular spectralert advance ceiling mounts, but now they have ones similar, but now they're larger and have the horn just like these. Are they the L series perhaps?

I wonder if multiple units being coded on a Sync•Circuit (R) would make the long initial burst before synchronization, like the Advances...

Cool! I have the p2Rl

3:56 - Let's say you didn't want a fire alarm, you wanted an agent release alarm. Watch this. Take an "agent" cover stick it on, snap it in, it just snaps right in and BOOM! You have an agent alarm. MIND BLOWN!!! (This was only meant to be a joke. I hope you found it funny!)

Coool

awesome!!

Why would you need a different color strobe for an agent release alarm? Usually an agent release would be triggered because of a fire suppression system, so the agent alarm would sound in the event of a fire as the fire suppression system activates.

I like the one with the word fire

COOL!

Where did You buy it I have checked the system sensor website

What would an alert rss strobe with a yellow cover at an army college be meant for

I just got a white one Yesterday!!!😊

My dads office suite these in all office suites and they got the small ones flush mounted to the wall

Why is the L-series a bit quieter than the Advance even though the sound is the same?

It'd be cool to mount the smaller one on the spectralert classic plate

5:19 the horn seems like it's trying to be a kidde smoke alarm ripoff

It sounds like a Spectra-Alert advanced (the first snd 2nd tone) the 3rd and 4th tone sound like a Mircom alarm

for those who are wondering what he means by directly mounting to a back box he means the back box is not in the wall but mounted on the wall

wait. is the l series the replacement for the advance series? or does it replace the classic series?

Nice video !!

The first tone sounds exactly like the SpectrAlert Advance what the second tone is not sure.

Yeah like it sounds like that, I love the strobe and the covers for the alarm. Nice thing!

Woah! To say the least.

The tones are a mix of the system Sensor spectralert classic and spectralert advance.

Can you test it with the simplex fire panel

What is the model number on the 3rd box? My son wants one for his birthday

why does the green strobe say "-65%" is that the lost candela due to color change?

Boom!

thats a HUGE bag for 4 screws :O

Where do you get the letter brackets and lenses

What is the name to the sand at the very end of the vidieo

Noice!

Is it as loud as the original spectralert advanced?

The L-series are cool

It's like a spectralert advance but it's not really an ear killer and it has a kidde smoke detector sound

How'd you get these? I want one and can't find any anywhere!

I Want to get those SO Bad!!!

Cooool

What is the Greensboro for

Is like a Spectralert Advance but with a different design and more tones

How do you remove them when you no longer need it?
