i got the alarm mainly for the smoke alarm (to go with my flame defender) but also it will enable me to get there before the cops and fire brigade, and perish the thought burglars, i will have the advantage over the intruders as they wont expect me so quick and i will have to stop growing operations asap so the intruders will pay with pain
you don`t need flame detectors if you are a professional grow room builder.
use steel box and safety glass lamp units, the profesional downlight ones for warehouses are heavy but best.
fit a new consumer unit with rcbo leak detectors, they are mcb`s and rcd`s in the one unit this prevents equipment malfunction, (mcb, mini circuit breaker). and prevents against electric shock ( rcd, residual current device ) with a 1.7 ms cut in power and prevents death.
the only place you can have a fire are your lamps.
the jack plug fittings on ballasts are known for electric arcing causing heat.
and the lamps themselvs can heat up and melt wiring etc..
i had a fire about 5 months ago and it was concealed in the steel warehouse lamp unit.
the connection at the bottom of the bulb in the center was totally melted and the light unit wiring inside the unit went on fire.
when i got there next day the lamp was off.
i replaced the wire replaced the bulb holder and it went on fire again, so i threw out the ballast and replaced it, and it is without faults now.
it is better to prevent fire than to be ready to tackle it.
you can also buy self extinguishing fire proof cable. expensive but fire is out of the question.
if you live in the uk all green and yellow earth wire sleeving is self extinguishing.
you will probably have more chance of your laptop going on fire than your grow room/house.
you dont need safety equipment in large grow houses, you just need smoke alarms and powder extinguishers as all of these types of grow houses have 24 hr maintenance and security anyway.
and you can use any type of cheap equipment you want.
but if your small grow room is unoccopied for 9 hours daily then you need to buy safety equipment, this is where people go wrong when they see huge grow rooms on u tube with basic equipment which can catch fire but forget that these areas are monitored around the clock.
remember that if you have a fan sucking air through a hot lamp and the lamp ignites with a fault your grow room will burn to the ground in minutes as fire and air mixed like that will turn in to a furnace in seconds.
