With copper prices higher than ever before and continuously rising, cabling has become an expensive procedure. Did you know Daisy Chain wiring in access control systems can save you time, labor, and money? It is estimated that the final cost of installation using daisy chain technique is 30% less than others.
What is daisy chain?
Daisy Chain is a wiring scheme in which multiple devices are wired together in a sequence or in a ring. I’m sure you’re wondering what distinguishes daisy chain from other techniques. The term daisy chain can refer to a few things. The first reference includes large scale devices connected in series, such as a series of power strips plugged into each other to form a single long line of strips. Another refers to the wiring patterns embedded inside of devices. Using daisy chain technique with central power significantly reduces electrician costs because it saves on the need to use 110VAC locally.
You may be thinking to yourself, what other type of wiring is there? The typical type of wiring you will see is called home run wiring. In home run wiring you take the wire from each component back to the control panel. The technique has been known as having a central location where all signals are distributed from.
There are some common misconceptions to daisy chain wiring:
· “If one device goes down don’t they all?”
Some believe because of the wiring, if one fails they all will. This is just simply not true. Millennium’s daisy chain architecture consists of a blockage module and blockage sensors. Each module and sensor displays on the virtual terminal indicating critical system parameters for the selected communication loop. There are advanced diagnostics as a value added feature, to assist in quick identification of system issues relating to sensor, communication, and power of the daisy chain wiring.
· “Aren’t the control panels now compromised because of the location?”
Some believe that because daisy chain wiring requires control panels to be in proximity of each door anyone can access them and break in. This is untrue with Millennium products. Millennium offers an electronic tamper-proof lock box system designed to securely house a control panel. Anyone trying to access the box will send a signal to the central workstation documenting the event.
Daisy chain technique means less wiring, resulting in more storage space. The cost savings are a no brainer.
