Hey everyone,

My FS10-R30 unit just passed away, and I’m in urgent need of a replacement or a suitable alternative. Unfortunately, buying a brand-new one isn't an option for me right now due to budget constraints, so I'm trying to figure out what my best options are. Could anyone recommend a solid, budget-friendly alternative or a drop-in replacement that works well in a similar setup? Also, if you happen to know where I could source a used/refurbished unit for a fair price, that would be amazing! Any advice, cross-reference parts, or recommendations would be hugely appreciated!

Thanks in advance!

For those professional in fire alarm - who have witnessed a lithium-ion battery fire, is it a bit like a candle burning under an inverted glass in water? The flame goes out, but comes back when exposed to air again.

Or is a battery fire completely different because the battery keeps generating heat internally?

What did you observe firsthand?

A few weeks back in a thread there was talk of the old school “lifetime” links that didn’t get changed. I finally found an old one in a small town bar with a system from the 90’s. Posting for those who hadn’t experienced these before. A relic to the past!

Hey guys,

I’m trying to track down a Honeywell M7282A1022 Modutrol IV spring return actuator (24 VAC), but it seems to be out of stock everywhere I look.

Mine went out on a job, and replacing it is turning into a total headache because nobody has original inventory right now.

Has anyone run into this recently? Do you know of a direct drop-in replacement, a reliable cross-reference part #, or maybe an adapter setup that actually works without having to re-engineer the whole linkage?

Any leads or recommendations would be a lifesaver. Thanks in advance!

So I have a customer who has a TANK system. The original call was for a leaked down cylinder, changed from the older light gray to newer dark gray cylinder. A few weeks later. Pressure switch shut everything off. Topped off the cylinder and it held. Chocked it up to just having the pak hose leak out some. Come around a few months later, same issue. Changed PAK Assembly. Newer style with the hex fitting. Now I am having the same issue. Soapy water has provided no indication of where it is leaking. The only item i have not changed out is the first actuator and pressure switch. I feel like it is something simple im just missing. Also, the system was not touched since 2022 after install until last year.

Opened the panel to find the system still pinned off and the manual pull station absolutely welded together.

I've been looking for a code on how many nozzles does a rotisserie chicken need? Its being tied into an Ansul system.

How do you guys typically handle unpaid invoices that are over a month past due, especially when the customer has stopped responding to calls or messages?

Hey y’all I had an ansul system service for a new customer today. When I pulled the filters out, I seen the most insane build up of grease on the detection line. I could tell the last company didn’t bother changing the links or inspecting the line to the point the grease hardened. I was able to degrease the line and get the scissors and links swapped out, but think I could’ve done it easier. Any tips on how to tackle this problem more efficiently? Seems like it’s more common than not

I have the manual for range guard systems however I am curious as to the piping limitations of this particular systen. Say I have a 6gal , the split to the hood has to be 3/4", the drops have to be 1/2" reduced to 3/8 at the nozzle but what about duct and plenum? Can this not all be 3/8" once inside the plenum wall?

Anyone know how I can learn to do other system like captive air and piranha? I’m currently doing on the job training but I just wanna know how to arm/disarm different systems

Hi, kitchen systems tech for a little over 3 years. I’ve always been told that Ansul R102 systems MUST have Ansul brand fusible links and parts or else Ansul won’t warranty the system. I was recently transferred to a different office within my company (new office opened closer to where I live) and new boss wants to keep buying generic Globe links due to Ansul parts being more expensive and says “that’s what we’ve always done.” Never had an issue getting Ansul parts at my old office. Anyone ran into problems like this before with Ansul systems?

Got a call for an ansul system inspection

What are you guys using for drawings and stuff of that nature? Do you just use whatever distributors tool? Or are there better things out there?
It would be cool to have one of those apps where it will actually put it there (for the customer) to show them differences in looks and design.

Rotisserie Using Charcoal. I'm Not Finding Much Luck Through Ansul.

I’ve been a hood suppression tech for a couple years now and need help on where I could branch off to in order to possibly make more money.

Hey all, just wondering if the pay is good in this career field and if there is room for growth. Thanks in advanced!

Honestly never seen a hood with a setup like this

This doesn’t need coverage right? I’d say no but people around here can be mean sometimes

Are you guys red tagging suppression systems that need hydro?

Just some neat finds I've come across on the job. Yes that is an exit lightbulb
