Wall System Test 15: System Sensor Low Frequency Sounder! 

I LOVE THAT ALARM!! I'm gonna get one of those asap!

You are at 3k! Good job! Getting closer to a play button!😄

Seeing that System Sensor low frequency sounder combined with the 4251-20 reminds me of what’s in one of the hallways of my elementary school. There was originally a Simplex 2901-9838, but I assume it died, so they just replaced it with a System Sensor low frequency sounder that looks exactly like the one in this video

I love the new camera it picks up the strobe flash a lot better keep up the good work

Cool test, glad to see another 4251-20 in service! So I imagine that this is able to sync up to P2R's etc without a problem?

I just got mine today and it's loud! Now one of my favorite alarms

Wow great video

Is this a 2 wire notification appliance?

how did you fix the simplex pull

I love that noise :)

great video mr. s.e.r. saftey!

in the description it says system test 14

Hi s e r safety you getting closer to the highest wall system test

i don't see the system sensor spectralert advance low frequency sounder very often

There is a simplex fire alarm with voice evacuation. It also plays a low frequency tone. It sounds like your alarm.

I like the new camera it seems to have better picture and are the newer simplex pull stations mad from plastic???

My old apartment had the sounder-only version of this in my unit.

What kind of camera are you using? Nice alarm.

How loud did it sound

I like the low frequency one. It is louder because low frequencies cam travel farther and high frequencies travel less but really high frequencies can travel way farther.

Hi s e r safety you are getting closer to wall system test 20!!!!!!!!!!!!!!!!

anyone can answer this question, How do i bypass the monitor module on a notifier nbg12-lx?

I definitely like the tripod.

holy crap it actually works. Surprise Surprise its set to Code 3. it is also outdoor use or indoors too.

Nice!

"The normal tone of a fire alarm won't wake up people" 1 Year ago, my smoke detector went off. It was, of course a false alarm. BUT IT WAS THE FIRST DAY OF THE FSA!

YOU aRE AWESOME

what the difference between the speaker strobes and sounder strobes? just wondering

We know what’s next genesis going to make low frequency wonder what it would sound like

this was at DeKalb Central High School, or for short (D.C.H.S.).

love the new camera :)

I like how the label says "SIMPEX," in stead of Simplex😄

cool!!

your voiced changed so muc h over the years

Wait shouldn't it be wall system test 15 since the last one was 14?

I have the sane exact one!!!!!!! is yours preset to high volume? mine is and it hurts!!!!!

I just saw the gentex commander 3

S.E.R Safety,what does S.E.R stand for?

Thats L O U D

Model NO: P2W-LF

Nice! I like the new camera. The video quality is much better.

I like to but my guinea pig didn't like the sound

The label says simpex but cool video

Haha the recommended video was your review of this and you sounded so much younger

I think these are most commonly used in hospitals.

If you got a Bluetooth speaker and put it up to your ear turned up all the way you would know what my fire alarm at school sounds like also turn it to speed 2
