The pre-configured Digital JetVent Control Center responds to varying levels of pollutants, as reported by the sensors, and varies the operating speed of the fan (s), and therefore the ventilation rate, by zone. This controller can also vary the speed of supply and exhaust fans and integrate their operation with overall ventilation requirements ...

JetVent: the principle The impulse ventilation system is based on a number of small, strategically located high velocity fans in place of the distribution ductwork traditionally used in car parks. the reduced need for, or complete elimination of ducting, the resulting reduction in system resistance means they are typically smaller and consume less energy.

The Digital EC series of Jetvent Fans represents the next step in fully integrated car park ventilation systems. These energy efficient fans generate constant air movement ensuring pollutants do not gather in dead areas. Energy Efficient. The JetVent Car Park fans feature advanced digital EC motor technology with integrated speed control.

The option of a factory-installed, fully integrated smoke detector allows the JetVent Control Center, or the building automation system, to monitor for smoke and respond accordingly.
Standalone Operation. Setting up a ZooKeeper server in standalone mode is straightforward. The server is contained in a single JAR file, so installation consists of creating a configuration. Once you've downloaded a stable ZooKeeper release unpack it and cd to the root. To start ZooKeeper you need a configuration file.
To start ZooKeeper you need a configuration file. Here is a sample, create it in conf/zoo.cfg: This file can be called anything, but for the sake of this discussion call it conf/zoo.cfg. Change the value of dataDir to specify an existing (empty to start with) directory.
Once ZooKeeper is running, you have several options for connection to it: bin/zkCli.sh 127.0.0.1:2181 This lets you perform simple, file-like operations. C: compile cli_mt (multi-threaded) or cli_st (single-threaded) by running make cli_mt or make cli_st in the src/c subdirectory in the ZooKeeper sources.
