Fire Alarm Breaker Lock, ELOCK-FA Circuit Breaker Lockout Kit with Lock & Tag, 2 Sets Red, for Fire Panel Safety, Prevent Accidental Shutdown

They were fantastic! It worked great with my square D breakers.

This Fire Alarm Breaker Lock (ELOCK-FA Circuit Breaker Lockout Kit) is a great, practical solution for preventing accidental shutdown of a fire alarm circuit. It does exactly what it’s supposed to do and adds an extra layer of safety and peace of mind. The kit comes with everything you need: 2 locks, 2 Allen key screws, 1 Allen key for installation, and warning stickers. I appreciate that it includes two complete sets, which makes it a good value. Installation was straightforward and easy, even though there are no written instructions included. If you’re not familiar with installing these types of locks, I recommend checking out the pictures on this Amazon listing—they make the process clear enough to follow. Once I looked at those, it only took a few minutes to get everything set up. One small thing I did that others might find helpful: I taped the included Allen key to the inside cover of the electrical panel so it’s always available in case the lock needs to be removed or adjusted in the future.

This kit is straightforward, easy to understand, and useful for preventing accidental shutdowns where breaker lockout really matters. The included lock and tag setup helps make the purpose obvious, and the parts feel durable enough for repeated safety use rather than one-time throwaway hardware. It’s a specialized product, but for the environments that need it, it feels like a practical and professional solution. Good to have where proper lockout procedures are important.

A good universal breaker lock. These are all metal so they are good quality. I just wish the set screws were torx security instead of regular allen type. I also wish the labels were blank and able to be written on to describe the 5 "W"s of the lockout.

these are tiny, but should fit on any lightswitch-sized lever. matching allen wrench included in the set!

These have worked great for us at work. We were having an issue where the fire alarm breaker was accidentally being shut off at night when closers turned off the lights. That resulted in repeated calls from the monitoring company all night— not ideal. Since installing these lockouts, that problem has completely stopped. They securely prevent the breaker from being turned off unintentionally, which gives us peace of mind. Another bonus is that they make it very easy to clearly identify the fire alarm breaker during inspections. It adds a layer of organization and safety that’s worth it. Simple product, but very effective for protecting critical systems.

I work in people's houses. Safety is my top priority, especially when dealing with electricity. The biggest fear is someone flipping a breaker back on while I am working on a circuit. I have used tape and angry-looking notes in the past. These methods are not very professional. I bought this breaker lockout kit to find a better solution. The kit arrived with two red plastic locks, two padlocks, and two "Do Not Operate" tags. The red color is very bright. It practically yells "do not touch this." I was at a client's house, preparing to do some wiring. I flipped the correct breaker to the off position. I placed the red plastic device over the breaker switch. It was simple to install and fit snugly. Then, I clicked the padlock through it. The whole process took less than a minute. This lock does more than prevent accidental shutdowns. It prevents accidental start-ups, which is what I needed. It provided a clear, physical barrier. No one could accidentally restore power to the circuit I was on. My client saw it and was impressed with the professional safety measure. It gave both of us peace of mind. I could focus on my work without worrying about getting a surprising jolt of electricity. This is an excellent, simple safety device. It is easy to use and impossible to ignore. The lock and tag make it very clear that a circuit is being worked on. It is a small investment that provides a huge amount of safety and professionalism.

These covers are great for preventing a fire alarm circuit from getting mistakenly turned off when employees are turning off lights or other equipment at the end of the day via the circuit breakers. You just need to make sure that your breaker is compatible (fits the space in the cover plate. Luckily these are sized to be pretty universal and fit most breakers. Depending on the building use/type a breaker lockout device like this may be required to be installed on the fire alarm breaker to prevent such accidental de-energizing.
