S.E.R. System Test 4: MASS & Century​ 

You are good and I believe that you are going to be one of the best engineer in this field

Your videos have improved a lot since I started watching in 2016 (but they have always been good). I like your editing. :)

I never heard a code 3 MASS siren, it’s pretty rad! The MASS is always awesome though, not much can beat it! That must be a heck of a good heater, it set off that heat detector super fast (or the heat detector is really good lol). I didn’t know the century pull station was made so recently as to have an addressable version! I thought it wasn’t made since like the 80s at best, I must admit I can’t remember when addressable became a thing though lol. Excellent video!

I just realized that Code 3 is (loosely) linked to the beats of a measure in sheet music. 1, 2, 3, / It rings three times, then on the fourth beat, it's a rest. The way everything correlates is insane.

S.e.riously cool! Keep it up!

This is my favorite video that you have made SER safety I like the system sensor mass series of fire alarms

I want my own system like you a box pull station and alarm

Who else agrees with me that the fire alarm sounds like a sea gull

I like all of ur fire alarm series

Sounds like a bird on steroids

At the Columbus library there is a 2903 light plate and the pull station is a fairaday shevran

Why doesn't a heat detector count as a life safety device?

Nice! Love the system! I liked the mass bell tone (I think) like in Unicode system test 2. One of my favorites!

Cool system alarms s.e.r saftey

2:23 I wish that was my school’s alarm sound, but it is just a generic hight pitched code 3 alarm :/

amazing video grant! i really like it, nice job!! Thinking of installing a system in our home

For people wondering whatvthe tone is at 2:23 its swept frequency on code 3

I have never heard that alarm before. It’s awesome😀

My favourite tone of the sensor mass is high-low

What tone did you use for the system sensor Mass?

I want to see a sprinkler if you have one

At 0:56 what happened?

aren't there panels that make that noise

Hi

Wow an early morning upload. Nice! Please someone explain to me why a heat detector is not a life safety device. It senses heat from a fire and sounds the alarm. How is that not a safety device?

Nice system test I love your fire alarm and emergency devices collection!

That video with the wheel lock bell on March time and the alarm on bell tone code 3 that would be cool

wasn't the mass sounder part of your unimode 10 ud system demo board?

I jump a little when it sounded, I didn’t expect it to go off that early

I did not see you put a BG-12LX on the garage system

Plz do fire alarm collection video

2:23 Sounds like a bird.

Sounds like a seagull lol nice vid

Swept frequency code 3?

0:56 Is that green screen

Great video can't wait to see more videos 😀

Without fire alarms you'd be nowhere and smoke alarms and fire alarms without them there would be a fire and we do not know at all we would probably not make it so let's say thank you for lunch for keeping us safe 3 2 1 thank you fire alarms for keeping us safe!

I saw a gamewell century in a church with a Gentex shg

Nice job, Grant!

That is a strange sounding code 3 for that fire alarm 2:23

Nice! Can you do a fire extinguisher collection video

That Fire Alarm Sounds Creepy…

It sounds similar to the ones in the UK in my opinion

I love your videos!!! 😂

Yay first

Isnt the mass 2wire and flashes on its own rather than 1 time every second?

Great video 😀👍👍

Dayum thats loud

Aunt Lee beep beep

Can the MASS do code 3?

Nice! The DIN code 3 sounds super cool!

Mass in distress!

Turn off the heater

I instantly played the video as soon as my notification appeared!

ser

Neat system

The fire alarm sounds like a dolphin

You have no clue where it will work or not until tomorrow morning and I can do that until after work so if I need it I’ll just take a break

You don’t even know the so loud at my house

I like it

I have that alarm

You just used a propane heater in a closed garage. Now let’s see your carbon monoxide detector collection.

SER you are not safe with co2 poisoning

MEOW!!!

Loud

It sounds like a bird

No Carbon Monoxide Detector "

Great video 🤗👍👍
