The pullstation has the switch reversed for a reason. It is intended to be used as a reliable emergency stop. If the cable was to break, it would shut off the device anyways.

[@PowderMill]

Quick thought from a 30+ year volunteer firefighter with a bit of generator experience. Similar to the “emergency shut off” systems now mandated at gas stations and fuel transfer facilities - The locations of manual activation switches are close enough to the dispensing equipment to allow quick access yet far enough to permit safe activation. How about installing several additional pull stations? In the garage near the FACP and/or on exterior wall of the house..? Knowing you, I’m guessing there is plenty of spare cabling and/or conduit already in place, but in the event it’s too difficult or costly to run, and considering it’s a residential install, you can even go the route of supervised wireless for non-required devices.

[@nics-systems-electric]

There's unfortunately no extra conduit going to the house the one in place is already full. If you know of any wireless relays that would be awesome for many things always wished there was something where you could trigger contacts on one device and it would wirelessly trigger the other side of the relay type idea.

[@PowderMill]

You are a very talented young man. Given your interest in a multitude of related fields, I’m going to suggest something I believe will be a growing subset of life-safety and communications. Though Canada has different codes and regulations, it’s usually very close to the US. The use of, and reliance on more advanced 2-way radio communications by first responders is becoming increasingly common. When I entered the field, we had a single mobile 2-way radio transceiver and only carried 2 portable radios aboard each of our fire apparatus. We operated on simplex VHF Low-Band (45.xxxMHz) and the portable radios rarely , if ever, could reach dispatch. The interior firefighting teams basically relayed critical info to the vehicle engineer/pump operator who would then act on the info and/or relay it back to our dispatch. After 9/11, the inability to communicate effectively (especially between different organizations) was brought to the forefront. Fast forward to the 2020’s, technology has advanced rapidly. Currently, each firefighter is issued a portable radio, spare battery(s) and accessories. Our radio systems have been upgraded and most public safety in my area (NYC / Northern NJ) uses much more advanced equipment and infrastructure. With the advent of APCO’s P25 tech, radios are now digital and have all sorts of specialized features to make critical communications possible. I could continue for hours, but just one feature of dozens is worth mentioning… manually triggered and sensor triggered “man down” features permit a firefighter in trouble can simply press a button and the radio ID and other info is transmitted to the incident commander at the scene and dispatch. A huge new market is now BDA/DAS systems. Essentially, to ensure portable handheld radios can function in large and high-rise buildings (concrete & steel construction make it difficult for RF propagation)…. The use of a rood mounted “donor” antenna and control systems link extend the existing public safety radio systems to internally placed specialized antennas and bi-directional amplifiers inside the building. Installation in new construction is relatively easy. Retrofitting is a bit trickier. But these systems are now being mandated and there are not yet an abundance of installation companies with the knowledge and experience. If I were starting over, as a youngster, I’d absolutely be learning everything I could about public safety radio systems, BDA/DAS (bi-directional amplifiers / distributed antenna systems) and integration with conventional fire alarm systems. Eventually these systems will be mandated EVERYWHERE…. AND, with that knowledge under your belt, the incorporation of similar non-public safety type BDA/DAS systems are critical to provide for cellular voice/data coverage in these same buildings. As cellular tech becomes more and more ubiquitous and everyone carries a mobile device requiring massive amounts of bandwidth for all sorts of applications, the ability to provide indoor coverage will be critical. Stadiums and large public gathering facilities are just one example. Just a thought…. :) My background = EE / firefighter / licensed electrical contractor / fire alarm + life safety systems installer / etc.. (+ Amateur radio operator aka “Ham”)

@@nics-systems-electric Do you currently have a hardwired Ethernet LAN drop out to the garage? I have been using an Ethernet based switching module and it’s cheap AND rock solid. It comes in 2 / 4 / 8 SPDT 5A relay models. They have a “sender” with the same number of inputs (selectable open to trigger or close to trigger ) Plus they have a mobile device app (iOS + android). I’m using them to open garage bay doors at a fire dept. When they are paged (2-tone sequential QC2) a radio receiver on the same frequency provides me a contact closure for 3 sec. The relay module is mounted 250’ away near the door buttons and there was a spare RJ45 Ethernet jack/port within a few feet of each device. I noticed they were going to release a Wi-Fi version 2.4 + 5.8GHz. I’ll look it up and I’ll post a link for you. Great channel and great video as always!

[@Uncleharkinian]

The pull station being normally closed makes sense to me, I just spent a month building a master interlock for a FM transmission site, I put a big red button on the front of the cabinet, when you smack it, it opens the 12V rail de energizing all the relays opening all the interlocks, basically shutting down all the transmitters, I would imagine for a generator, like a front panel for one of my 50 Kws is the same, some sort of 12v reference or maybe just the battery, that if broken forces a shut down! But since your tying into a fire alarm cabinet then yea swapping it makes sense for that purpose!

[@nathanharris-su4qn]

hi Very nice project, it’s always good to have a manual trigger to shut down the generator for emergencies

[@Trump985]

All you needed to do was put a ball valve on the fuel line, you could even attach a cable to the valve and have a remote shutdown. In case of a fire pull the cable and not only will you shutdown the genset (s) but also shut off any fuel the might be feeding the fire. This is what we do on boats and we route the cable to the outside of the vessels so if you have an ER fire you can shut everything down from outside. No need to overengineer it, a ball valve some cable and possibly a few shives if your going to route it around corners.

[@achannelwithnopurpose1977]

Like the idea. Lots of reasons i can think of to have an emergency stop.

[@snowballinflatableandgaming]

I believe the reason for the normally closed pull station is for redundancy. If power is lost it automatically activates the e-stop. This is done because if the wire is damaged (meaning shorted or cut) if it was normally open the pull station would no longer activate when pulled because the circuit wouldnt be able to be completed.

my god that siren would make me nuts 🤣 Great project love the color scheme and defiently a nice addition. Also you did add zone 9, but you dint click enter the first time u went direct escape thats why it dint set. And as other people said. the reason why it was common closed i think the idea was to have it on the monitor module as a normaly closed so if cable were to break it would shut it. really the chances of a cable breaking SHOULD be none if correctly installed so really shouldt matter but here we are

[@AT_Videography]

I think that was set as a normally closed so you can wire it directly to the ignition system or fuel system of the generator. Pulling it will open the circuit and either kill the ignition system (spark plugs) or fuel system (fuel injector power), thus shutting doen the generator. Food for thought

[@nics-systems-electric]

The generator needs to be removable which is why I have quick connections from the controller to the generator the fire alarm relay ties into the controller only therefore not requiring any additional connections. So I needed the shut down station to interact with the fire alarm system to use the same relay so no additional connections required.

[@BlakesBench]

[@vrryan6]

opening clip with the zooming out reminding me of Waldo’s World videos

[@imark7777777]

I would suspect that it's set up as a normally closed so that when you pull it it breaks the connection between the control line to an automatic generator or UPS which I believe operates on the opposite principles from fire shorting two lines together.

Here’s my two cents on this idea it’s all well and good, but I would’ve put the emergency stop on the other side of the generator box facing the house so if the garage was on fire, a fire department person wouldn’t have to go to the other side of the box and be even closer to possible flames just a suggestion that kind of makes a little bit of sense that’s what I would do if I had a generator box like that which should would be a useful thing to have here at my house I thought the power doesn’t go off that often out nowadays

Because more likely than not the system is still operable and will still provide the function needed. Between fire detection and sprinkler system the fire should be controlled before it gets as bad as you have mentioned. The fire would not start consuming the whole building but as something small. Therefore there is time to handle the situation and in the case of the generator running an option to shut it down.
