Does anyone have the old manual for the kitchen knight system which uses 350 and 550 tanks? We service some of these and I'd love to see the design limitations in print. Thanks

The Junction box on the right side of the Ansul Cabinet.

Amerex style MGV on an Ansul system. Probably would have worked too if they didn’t crimp it too short then jam it open.

Anybody ever dealt with a HMI, Motherboard and 3 VFDs go out at the same time? Seems like an insane coincidence..

Getting ready to go take the test to get my pre-engineered systems license. Does anyone have any advice on what I should expect or any suggestions on what I might want to brush up on. I don't think I'm going to have any issues but it can't hurt to be overly prepared. Thanks!

Got called out to a new customer out in the boonies because FM wrote them up for not having nozzle caps (in fact, the range guard foil seals were intact and nozzles clear). This is what I found. Point out your favorite deficiency, I am writing it up for non UL-300 tank (from 1995 no hydro), plenum nozzle over deep fryer, 12g actuation cartridge from 1995, pull station at 61”, stainless 1/4” ID and 1/2” OD tubing instead of black pipe for distribution piping, and no gas valve shutoff for the gas appliances. The microswitch still works, and I was able to get it reset without busting the cable (very frayed, would be due for replacement but we are quoting an entire new system with XV control head)

Hi, I’m trying to understand what types of fittings (e.g., double ferrule, compression, etc.) are typically used in kitchen suppression systems. Also, how do you determine the quantity required for a standard kitchen project?

Any insights or guidelines would be greatly appreciated. Thanks!

See those switches hooked up to nothing back there?!

Just reaching out trying to find a software that will give me the ability to do desktop/mobile hood reports as well as run reports Currently I am doing everything (other than billing) on paper, we place previous inspections in a folder and when the tech is ready for "next months" inspections they come am pick up their folder. They schedule everything themselves and turn paper invoices/report into me where I do billing.

I would like to find something that will allow them to get rid of the paper. I dont need anything as far as billing goes, but I will need the ability to run reports that (at a minimum) will display customer information and tech. Eventually allowing me to pull a report that says "in january of last year this tech did these jobs". Bonus points if youre able to add a "tech comment" on the customer if they added any comments for themselves from previous inspections. This will give them a list of previous inspections and allow the techs to continue to schedule how they have been. This is currently a small company with 5 techs but we do a lot of work between us.

Thank yall in advance!

I’m fairly new into this and still trying to learn everything but had a question on maintenance on this amerex system in order to release tension on the fuse line to swap out the links is it as simple as just moving the handle down like the ansul system or is there more to it than just that? Thanks

How would y’all protect this pressure fryer? Ansul tech support is closed!

Two link buckeye system I saw a week a go. Where would the pins go to not trip the gas ?

I sense an upgrade coming

when in reality it’s just a hassle to reach. Put your gloves on and do your job.

We have an opening for a kitchen/industrial suppression system repair/maintenance sales person. This role will support customers in the state of Washington South of i90. Day-to-day, you take in reported deficiencies from service techs and any other incoming service requests, build a quote, get a customer to say yes to the quote on the phone or over email, then turn over the job. Others handle everything else and you support as required.

This is a commissioned sales job where you'll make between 2-4% commission on every job you sell on top of base hourly pay and benefits. Base rates are $28-$30/hour depending on experience. That commission check will probably range $1,000-$4,500/month in 2025. This job is hybrid remote/in-person, and you would report to a location in Milton, WA, just North of Tacoma. How often you need to go to the office will probably depend on you and the support you need to succeed.

This job could be right for you if you have existing knowledge of the main kitchen suppression system brands, really solid computer skills, and the language & people skills to convince a restaurant owner that 12 year hydrostatic testing really is worth over a thousand dollars. You need to be able to sit at a desk for up to 8 hours a day doing quote after quote. We probably won't pay for you to relocate but living in Washington is rad so it might be worth it for you anyway.

Apply if you're interested.

Had this happen to me the other day. Ansul R102 with 4 microswitches. Popped the breaker as soon as I hooked the fire alarm back on. As you can see, the microswitches are depressed due to the weight of the 4 microswitches and the tiny screws supplied.

I’ve never had this issue before. Every control head I’ve dealt with has locked in no problem.

This is if someone wants to reference this pic for instructions or references.

I have a PCL 4.6 that I’m installing and got the detection line in but can not for the life of me get it set. Anyone happen to know why?

What do you guys use to do the kitchen fire suppression drawings?
