Frustration!

The greatest industry challenge we regularly witness is the frustrated client whom wants to use another a vendor and feels trapped with the vendor they have now, “Vendor captivity” in BMS, Automation, HVAC and Access Control cna cost landlords and property manager more money than it should. Our goal is to “unwrap” the client and offer them freedom of choice, at a low cost.

How Can We Help?

The initial strategy is a simple process, one visit, at now cost will establish if we can assist.

  • Establish if full or part access is available via the current passwords
  • Are full programmable access passwords available?
  • Is the communications protocol of the BMS a genuine open protocol or is it “proprietary open” or closed?
  • What is the age of the BMS?
  • What brand is the BMS?
  • Is there a “JACE” involved?

We are Licensed Electricians

Being an electrical contractor means we can legally and safely open a switchboard and work on it in line with the faults of your control system.

vendor captivity can be negated with the experienced and knowledgeable technicians

Vendor

We can install additional panels, connect them into the building without delays ro modify the switchboard to incorporate the controllers directly.

If there is an issue with a 240 volt relay or some other issue which comes under the electrician’s domain, we can fix and/or repair while we are there. There is no waiting for another contractor and there are fewer engineering issues.

Hardware Replacement

Replacement of the BMS hardware can depend upon the vintage, the brand of the system, and the communications protocol (assuming we have full password access). Often our buying power will obtain a good price for your controller, even when it is proprietary, this because our supplier know we are not involved in construction and don’t compete in the construction industry. Purely facility services. Our suppliers understand they are being looked after and, like us, are interested in the long term client relationship.

Hybrid System

To reduce costs we can often create a hybrid system which works, we will explain the limitations, if any, to you and any performance issues which might arise. This strategy is not a favorite, but in older BMS systems it can solve a problem, without a full upgrade.

Pneumatic Systems

Avoiding Pneumatic Systems can reduce vendor capita or upgrade modify the system

Pneumatic control systems can be interfaced into digital systems for minimal cost

There are still parts available and there are “electric to pneumatic” transducers (E-to-P) which can save you money and still offer the benefits of having both systems.
The benefit offers our client a staged approach to upgrading the entire system. Instead of one huge capital expense, we can upgrade the controls to digital while keeping some of the more expensive field actuators pneumatic with a view to upgrade these at a later date.

Field Equipment

Sensors, actuators, transducers, switches, relays, valves, and other peripheral field equipment is usually purchased via a third party, even by the major companies in the industry, just re-branded. Typically field devices are 24 volts A/C, 0-10 volt signals or 4-20milliamp signals. Suppliers for this equipment are all over Australia and generally have most requirements for commercial applications in stick or just a few days away.

High Level Interface – HLI

The High level interface between original equipment manufacturers (O.E.M) generally works the pneumatic condenser-water-valvesame way. Many are bacnet and Modbus communication protocols, with Lon Works slowly falling away as the other protocols take the market. HLI is a very useful method as it “integers” are transferred between devices with the need for any calculations, the calculation is done inside the O.E.M equipment. Chillers and energy meters are the most commonly used HLI in the BMS system.
