Wireless Technology
we can create a truly ‘smart’ system. Cloud- based applications are key to using this data. The ‘Internet of Things’ does not function without the right collection and analytical tools to interpret and use the information intelligently.
Wireless technology is also making headway in the development of intelligent sensor products. For example, Sontay’s RF-IOM-4A-4U input/output module works in conjunction with SonNet sensors and routers and acts as a local I/O with connectivity to typical HVAC equipment, such as fan coil units or variable air volume boxes. The module can take any 0- 10Vdc, 4-20mA, resistive or VFC signal from wired devices in the field and transmit them to one of SonNet RF-RX receivers which in turn communicate the information to controller. The strategy within the controller uses this information to calculate control values, which are then passed back through the I/O module to alter damper positions and other output connections in the field.
In the early years, SonNet receivers collected data from the network and communicated them in 0-10Vdc output to the controller. Over time a receiver compatible with a JACE controller through a Niagara framework was developed and shortly after a RF-RX-B SonNet receiver, was launched, which allows easy integration to BACnet controllers. The new generation of ‘smart’ buildings can also benefit from wireless technology as it can be easily connected to internet-based communication protocols. For instance, Sontay’s new RF-RX-B Network Radio receiver automatically maps data from SonNet devices into BACnet objects, which are transmitted via BACnet IP communication protocol, using a simple web browser interface. As a result, with this new network receiver, a SonNet network can now easily be integrated a BMS via BACnet IP.
All in One
Sensors can also now range from a simple thermistor-based room temperature device to a sophisticated smart protocol communication sensor. The latest multi-sensing products offer an increased level of functionality, tailored to suit any application. They provide complete
environmental sensing within a single unit, with a whole range of variables being measured including temperature, CO2, relative humidity, light level, air quality and fan speed. Popularity is growing for these multi-sensing devices as they are quicker, simpler and more cost effective to install and utilise just one cable to send all data, no matter how many variables are detected. With wireless technology, many of the barriers
to installing an intelligent Building Management System (BMS) have been removed. It is easy to install, reliable and cost effective and if electrical wholesalers can get this message across to their customers there is a huge business opportunity.

Wireless variations of intelligent control
devices are becoming much more readily
available. This makes it easier to build, extend and increase the range and capabilities of a unified, integrated system.
