Mejasg Large Fireproof Safe for Home (52L) with Alarm, Silent Mode & A4 Fireproof Bag
Product description
If you’re looking for a home safe, it usually comes down to two things: keeping valuables out of sight and giving you some protection in the event of a fire. This Mejasg Large Fireproof Safe for Home leans into both, with a fireproof A4 document bag, a digital lock with an alarm mode, and mounting points so you can secure it properly.
That said, it’s not a watch-sized “bolt it to the wall and forget it” type of purchase unless you’re happy with a domestic-level safe. Over the door thickness, bolt count and the general build are all described, but you’ll want to treat this as a practical home solution rather than something designed for high-end, professional threat models.
Key takeaways
On paper, this is a large home digital safe designed for everyday security: money, jewellery, medicine and A4 paperwork. The removable shelf helps you organise the interior instead of just stacking items. It also includes a fireproof A4 document bag, which is the bit that matters if you’re trying to protect paper and records as well as cash.

Where it gets more interesting is the alarm approach. The safe mentions an alarm mode triggered after three consecutive wrong inputs, and there’s also a silent mode so you can manage noise depending on the time of day. There’s even an interior sensor light to see what’s inside in darker conditions.
What it’s for (and what it realistically covers)
This safe is positioned for home storage rather than commercial use. If your main goal is to reduce “casual access” risk—misplaced keys, curious visitors, children wandering in—it fits that brief. It includes both an emergency key method and a code method, so you’re not locked out if you misplace a key, provided you still have access to the code route.


A simple micro-scenario: you come home, drop an A4 set of documents into the fireproof bag, place the bag on the floor of the safe, and use the removable shelf above for smaller valuables. In the evening, when you open the door, the interior sensor light makes it easier to find what you need without using a separate torch.

Keep in mind, though: the “more than 100 million combinations” claim relates to the digital code range, but it doesn’t automatically mean it’s immune to determined attacks. It’s about deterrence and access control, not invulnerability.
Where it stands out
A few elements look genuinely useful for day-to-day ownership:
- Fireproof document approach: the included fireproof A4 bag is specifically aimed at protecting papers/money, rather than relying only on the safe body.
- Build and access resistance (as described): solid cold rolled steel, anti-pry and anti-rust messaging, and a thickened front door with concealed hinges.
- Organisation with the removable shelf: the safe is large enough to separate categories, and you can take the shelf out when you need more height.
- Control over noise: an alarm mode after wrong inputs, plus the ability to turn sound on/off.
- Practical visibility: the interior sensor light helps when you’re using it in low light.
- Mounting for stability: it has pre-drilled holes on the back and bottom with mounting screws included, so you can bolt it down.

What you should check before buying
Before you commit, it’s worth double-checking a few points based on how these safes usually get used:


- Batteries aren’t included. If you’re planning to rely on the digital code immediately, remember you’ll need power on day one.
- Space planning: the interior dimensions are provided (13.38"W × 11.81"D × 17.32"H). Measure what you want to store—especially if you plan to keep larger jewellery boxes or document folders.
- Your preferred access method: you can open via emergency key + knob, or via a user/master code (3–8 digits) + knob. If you’re the sort of person who forgets codes when stressed, you may want to be very deliberate about how you store that information.
- Alarm/silent expectations: the description tells you there’s an alarm mode after three consecutive wrong inputs and that you can control the sound. If your household is very noise-sensitive, confirm silent mode works for your situation in practice (for example, when you’re upstairs or asleep).

Is it worth it?
A solid pick if you want a large domestic fireproof safe that’s geared towards everyday security: hiding valuables, keeping A4 documents in a dedicated fireproof bag, and using a digital code with an alarm that you can silence if needed. If you’re willing to bolt it down using the included mounting screws, this becomes much more credible as a practical home storage solution.
It may not be the best match if you’re expecting a truly premium, specialist-grade safe. On price-to-feature terms, it sits more in the “home security with fireproofing for documents” bracket than the “serious safe for high-risk scenarios” bracket—so if that’s your goal, you may want to look at options designed and tested for more demanding requirements.
