Installing a system sensor L-series Low-frequency sounder 

When you can troll the haters and entertain the rest of us at the same time, that's something special! 😁😂🤣

Oh my, Nic! What a blast from the past!

I'm really excited for the new system test

What a great video lol it was so funny!! I'm glad you are safe after doing that!! Btw your tools are cool!! Have fun my friend! ...

The safety thing is hilarious! Thanks for the entertainment!

You're amazing

Spectralert advance: ITS OUR RAREST DIVICE EVER THE SPECTRALERT ADVANCE LOW FREQUENCY SOWDER HORN STROBE!!!!!! System sensor L series: Hold up that my low frequency sounder horn strobe

Oh yeah! That will make a loud system test!

oh my god, i could almost feel the Arc Flash coming the whole time

Like your videos btw

you could get a white l series LF and cover lettering while putting the letters co on it for temp 4 carbon monoxide

I'm very glad you took the necessary precautions to ensure your safety during this dangerous procedure. Do you also make sure to isolate yourself from ground prior to handling the 9 volt batteries in your smoke alarms?

Cool system senser

Amazing.. you gotta becareful those 24v DC appliances can kill you in a flash.. It's unbelievable how many don't follow these safety guidelines! Anyways haha, great install and video as always!

LOL 😂 I knew from the beginning of the video nobody had to wear an ark flash suit

Awesome

I just got a new EST genesis chime strobe and I am super exited :DD Also it's me, black IS AMONG US

I have one of these low frequency sounders and its white but it was a Hassel to mount off camera

"taking a leak from really high up on a ladder" 😂💀

24v is also used in doorbell systems and even smart doorbell buttons use 24v dc

Ooh I rlly want one of those I have the hrlf

We had est mechanical horn strobes in the restrooms in my elementary school and I’d still wonder to this very day how people would react if it were to go off

Cool

Lmaoooo when you changed your clothing at <a href="#" class="seekto" data-time="110">1:50</a> it killed me XD Great vid and installation btw!!!

You know, I think that Low-Frequency sounders should be code in hotel rooms, and other bedrooms in residential buildings.

You can program the panel that the sounder go off and do temp 4

Model: P2RL-LF

why did you put a horn/strobe in the bathroom?

👍🏾

You looked ridiculous in that suit lol

Takes leak on ladder while wearing arc flash suit!
