SAFETY INSTRUCTIONS
The iPBx range of biometric readers have been designed foremost with safety and ease of installation in
mind. All our products are DC (Direct Current), 12V (low voltage) devices, and as such, do not specifically
require the availability of a certified wireman when being installed.
Using commonly available RJ45 connectors, the iPBx range of readers connect directly to
the IntelliRelay™
using standard Category 5e network cable (
*1
), commonly known as Cat 5 cable. This cable provides the
reader with power, network communications, and the unique iPB IntelliLink™ connection, which will be
explained further in later chapters.

Whilst the iPBx readers use standard or conventional cabling, they do
NOT USE A STANDARD WIRING
convention. This is for multiple reasons, including the following:
Security
:
A big concern for any company is physical access to their networks. iPBX biometric devices
often sit outside a building, as they are required to grant access. To ensure that the device
cannot simply be removed from the wall, and used by any other device for internet access,
iPulse mixes up the cabling to ensure that only iPBX devices can access the network through
the IntelliRelay.
Distance
Standard Cat 5 cables support a distance of up to 100m. To make sure that all of our signals,
including power (
*1
), can run this distance, iPulse uses a specific cable pattern to reduce
interference, and boost signals. Therefore, in distances over 5m, only the iPulse cabling
method will work.
*1
All iPBx devices require a standard 13,8v input, and supplying voltage that is higher than
this can cause significant damage to the device. Having said this, voltage drops over
distance, and as such, when the distance between the iPBx dev
ice and the IntelliRelay™
reaches greater than 40m, it is advisable to seek expert advice on how to inject higher
voltages at the opposite end to allow for the drop over distance that the readers will
experience. No greater than 17v should EVER be inputted
to an IntelliRelay™ however,
to avoid damaging the unit.
The following diagram
–
which is very similar to the TIA/EIA 568B standard, should be used for all cables
linking an iPBx device to an IntelliRelay™
. The only key difference
–
and the easiest way to remember this
diagram, is that all colours should be paired together, unlike the TIA/EIA 568B standard, where the middle
4 cables are mixed up.
In general, ANY wiring diagram where all pairs are together, ie, Orange and White, Orange, then Green &
White, Green, then Blue & White, Blue and finally Brown & White, then Brown, is acceptable.
