Seeing a few stories of bitcoin/litecoin miners setting on fire , placing a firealarm next to your miners wont prevent the fire if your not home, someone needs to create a device that would instantly put out the fire on your miner else you might not have a home,THOUGHTS??

I was also looking about this.

For obvious reasons, water and powder cannot be used as they will harm the circuitry.

However, this automatic extinguisher releases a no-residue electronics friendly gas.
It was specifically designed for electronic equipment and server towers.
It activates at 79 Degrees Celsius so you should put it a bit of a distance away from the rig or it could go off when the miners get hot.

It's called a CO2 fire extinguisher.   ???  Point at base of fire and blast away.

He said when you AREN'T at home.

The product you are talking about already exists, They use it in data centers and on commercial cooking equipment.  Some use c02 and some use halon.  However, good electrical practices and regular inspection would probably be a better option.

I keep my rig outside just in case something like this happens.  Sits on a concrete pad away from the house with a cover over it in case it rains.  Harder to set the house on fire, cooled naturally by the outside air....it's a win-win

Put my expensive hardware outside for the elements???? RU serious???  Can't trust your HW?  If not...you're doing it wrong!  I believe in the auto fire extinguishers idea though thanks for the link!

Don't create a rig that is likely to catch on fire. Prevention is better than cure.

From memory I think the systems were Halon or co2 (long time ago) however the systems I have seen usually where activated by the fire alarm system and incorporated disconnection of electricity supply - no point putting it out if it will reignite..

Another point to note- the rooms had strobes to indicate activation ( in addition to audible ) primarily to prevent suffocation..  :o

I believe a normal ATX power supply has built in protection, I have been considering an alternative DC supply, this would require some proper distribution, perhaps automotive fuses, to prevent such an occurrence.  Look for RV distribution boards on ebay perhaps.

Your main 12V DC could pass through a 12V relay/contactor and run its coil of the aux contacts of a smoke detector (most mains smoke detector manufacturers do an auxiliary unit for similar purposes)

Just make sure your contactor uses a hold on circuit with a manual "on" button, so it wont re energize in your absence.

That makes a whole lot of sense.

Yep,  They dissipate all of the oxygen so nothing can burn.  You don't want to be in a room when one goes off.  Some are activated electrically(24v) and some use a big ass spring and a lead link.

BFL didn't mention it in their brochure!  How was I to know?

I know right?
Absolutely shocking that we should have to take basic precautionary methods to stop fires.
Scandalous!

I've seen the lead link system in boiler houses, they sit just above the burner in front of the boiler door. There also used for fire barriers in AC ducting.

For those interested it is basically to pieces of lead that overlap and is held together with solder that has a set melt temperature. Good for high heat fires not so good with smoke fires.

Anyone interested in rigging up a smoke detector to auto shut of the supply, I can provide some advice.

BFL don't care about customers. They have proved that over and over.
