It is important to be aware this strategy, fire detection and protection requires special attention. A recent article in Search Data Center gives some good advice: Hot-aisle/cold-aisle containment – a variation on the traditional data center best practice of hot-aisle/cold-aisle design – is a way [...]]]></description>

It is not unusual for unsupervised and inexperienced painters to paint over the pipe, blocking the microscopically small aspirating holes. These holes are used to suck samples of room air into a detection unit that can act as an early smoke [...]]]></description>
