Whelen 295SLSA1 in a Helicopter Hanger 

Thanks! I have a video of the rumbler in there too, but that will be posted next week.

allintodrumsandguns awesome! Must had sound amazing to listen to it in there. Thanks for sharing.

It was. I had to wear hearing protection because of the added amplification. But that echo is pretty sweet to listen to in person.

Mr.Firefighter I hear you! XD Though, I have another video [hopefully] coming soon that might have some red and white, so stay tuned!

Thanks Justin! They are super bright, and I really enjoy them!

allintodrumsandguns no problem I always like seeing what other people do with things I sell them. The best thing to do and fun thing to do is build things out of it

I agree 100%. And thank you for the opportunity.

Thanks! I can do that. I’ve already prepared a couple other videos, but I can definitely do that one.

hey i'm new into the sirens and i got a code 3 mastercom b with just the red cable and i need help with getting the correct wires and power and all. just a noob right now

Danman16 No worries. To power on the unit, connect the big red wire to the positive terminal. There should be a slot on the bottom right of the unit, under the power wire as next to the fuse, where you will need to supply a wire, insert on the male connector, and run that to the negative terminal.

@@allintodrumsandguns would it be possible for you to provide an example and is it a special wire or just a wire?

Danman16 I don’t have a Mastercom B, but the recommended wire for the negative terminal is 18 gauge. There are several digital manuals available online that have wiring diagrams for the Mastercom. Or, you could check out Justin Selvage’s RU-vid account, I think he may have a video on the wiring. He owns at least one Mastercom.

Shhh, don’t tell anyone; I did buy it, but still need to find an amp for a decent price.

Whats a good email for u?

Thank you for asking, but this one is part of my private collection, you can check eBay for a good selection to choose from.

StrobesNMore should have it

Hmm, strange. Could be an internal problem if they’re not changing when pressing the button on the back.

AlexandersAlarms Deactive - channel dead ...it was a self correcting problem. XD
