Integrated BMS

Integrated BMS

What is integration?

Integration brings together 2 or more different control systems (i.e. Fire + CCTV) in a building or complex, so that they can operate as one system. This has a number of advantages to previous building management systems:



  • greater degree of simplicity/usability for the end-user
  • customers can choose the best system from each particular discipline without fear of compromising compatibility
  • building cause and effect strategy can be programmed through the integration layer
  • energy efficiency and dramatically reduced consumption can be achieved via the integration layer
  • the integrated layer provides true optimization of all the connected building systems




Integrate1: a. complete, form into whole; made up of parts; whole

Integrate2: v. complete by addition of parts; combine (parts) into a whole


Recent trends in design and specification have tried to use the well developed HVAC (heating, ventilation and air conditioning) controls equipment to take on a larger role in building management and automation than what it was originally designed for. More and more we see new buildings where integration is seen as a way of "bolting on" more information or compatibility into a HVAC control system - often with increased costs and to the detriment of the overall building performance.


True integration overcomes these problems, thus allowing manufacturers to develop their systems without constraints. Whichever method is required, Tyrrell Systems Ltd are able to offer help and advice to provide the best solution for the problem.


Tyrrell Systems can offer a wide range of integration solutions to best suite your needs. Tyrrell Systems have been a North Approved Systems Partner since the partnership scheme was introduced in 2000. In addition to being the first appointed NASP Tyrrell Systems are also a Tridium Niagara AX Developer and a Tridium Systems Integrator. This unique position allows us to design jobs with the most suitable integration equipment on the market giving you the freedom of choice to choose the building systems that meet your requirements.

The PS00105 range of air differential pressure switches are suitable for low differential pressure switching applications, and are ideal for providing indication of fan status or 'filter dirty' conditions in air, non-combustible, non-aggressive gases in air conditioning and ventilating installations. The switching knob is mounted under the cover to avoid tampering.



  • Close switching differential
  • IP65 housing option
  • Duct fixing kit included

The TH00105 uses the latest high accuracy RH & T element, and offers options such as set point adjust momentary switch and fan speed selection, together with a multi-line backlit LCD display. A 0-10Vdc override status input option is also available, allowing occupancy indication on the display.

4-20mA, 0-10Vdc or 0-5Vdc outputs for temperature and RH are available as standard. A custom output range for temperature can be requested, between 0 and +50°C.

A directly connected passive thermistor temperature output is also available, as an alternative to the standard active temperature output.

  • Multi-function sensor
  • Fully configurable LCD Display
  • Direct thermistor temperature options available
  • Blends into the fabric of any building

The TH00105 range of humidity and temperature sensors offer the latest technology high precision and accuracy RH & T element, and installed in our robust 600 series housing. The housing has an added benefit of being easy to install with the hinged lid, which can also be screwed closed to make the unit tamperproof.

An optional multi-line backlit LCD display is available, along with a direct PTC/NTC sensing element. Also a
custom output range for temperature can be requested, between -20°C and +50°C.
