Security And Monitoring Sensors

The sensors are the heart of ALLNET building testing and provide a comprehensive way to obtain data about the environment and climate and use it, for example, to control actuators and I/O inputs via the sensor meters.

Measure, control and regulate automatically and independently


ALLNET for years been pursuing the concept of intelligent control of processes in building over network and Internet. Intelligent building not only offers comfort, but actively promotes the reduction of energy costs.


Centrally managed and via network / internet accessible the ALLNET Home Automation products allow intelligent building automation regardless of time and location.


The ALL4454 smoke detector/ sensor can also be used for detection of gases.

Multiplexing - Note to the operation of several sensors on one sensor port


Basically, it is for the ARM and MIPS-based systems possible, unlike to the ALL3000/4000 to operate more than one sensor on a physical port.


Standard hardware requirement is that the sensors are equipped with 2 RJ45 connectors so that the sensor signal can be continued to the next sensor. The total cable length of 100 m does not increase thereby.


So that the sensors can be uniquely identified by the devices, it is necessary that these sensors have different software-I2C chip addresses and IDs. Sensors with the same address and adjustable chip ID can be combined. For sensors without adjustable ID address only one type of sensor can be connected per port.
