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.
