iPBx to IntelliRelay Wiring Diagram
There is no reason that anyone who is certified to work on standard networking cables cannot work on the
wiring between the iPBx devices, and the IntelliRelay™. Many network cables which use the PoE standards
contain much higher voltages than the IntelliRelay™ puts out.
Having said this, the IntelliR
elay™ itself connects to a power supply directly, and this power supply is
normally connected to the AC (Alternating Current) mains electrical supply. Although this power supply is
not a direct part of the iPBx installation, it is highly recommended that only a certified wireman connect
the power supply to the mains power supply, and that even the connection of such a supply to the
IntelliRelay™ via the 12V output should be performed by the same person if possible.
It is highly recommended that a good quality (at least class II) power supply be used, which supplies a
minimum of 1A output at 12V DC. All power supplies should conform to the Safety Electrical Low Voltage
standards and should always be earthed where possible.
The iPBx range of biometric products were tested using power supplies that meet the UL60950-1, TUV
EN60950-1, CCC GB4943(RS-50 only) safety standards, and when used in conjunction with this type of
power supply, are known to conform to the Safety Electrical Low Voltage standards.
For wires c
onnecting from the power supply to the IntelliRelay™, it is recommended that AWG20 (
*2
) cable
be used, and that this distance should not exceed 10 meters from the power supply to the biometric reader.
Where possible, and for maximum reliability, a length of 5 meters is recommended, and preferred.

Prior to connecting the iPBx reader to the IntelliRelay™, a voltage measure of the power input block should
be taken. This should measure between 12V (minimum) and 13,8V (maximum). Lower voltages could
provide insufficient power for the device to run correctly, and higher voltages could damage the
IntelliRelay™ which has surge protection circuitry, and is thus designed to switch off, or even blow, if too
much voltage is supplied, in order to protect the biometric reader.
When connecting your iPB4 to a power supply, it is important to know how much power the device will
draw at peak, and what the average consumption is. This is very important especially when connecting the
device via PoE.
