Line-Of-Sight - impro HRR901 Installation Manual

Maximum Data Communications Distance
The maximum cable length between the Impro Quad Receiver and the Terminal or
Controller is 150 m (164 yd.), using a good quality multi core cable. The cross-sectional
area of the cable conductors must be at least 0.21mm
and "D" conductors. To mitigate interference, cables should be a screened multi core
cable.
2
Solder a 2.5 mm
(insulate the soldered joint so that it is not left exposed) and route this wire to the
nearest Electrical Mains EARTH terminal – most often this may be same power socket
used by the DC Power supply for the Controller.
NOTE: The Quad Receiver (Device) end of the screen drain wire must not be
connected to anything.
Serial Number Label
The loose Serial Number Label (packaged with the Receiver) identifies the model of
Receiver and its Serial Number.
Installation Considerations for Best Performance
When installing the HRR900-0-1-GB-XX, it is important to consider the location and
environment for achieving optimum performance.
Location
Mounting the Impro Quad Receiver or Antenna mid-distance between the expected
point of entry and exit may balance the available operational range between both
locations.

Line-of-Sight

Locating the Impro Quad Receiver or Antenna within line-of-sight of the expected point
of entry and exit may result in greater received signal strength, increasing the
operational range.
Integrated Antenna (HRR900-0-1-GB-XX)
Mounting this Impro Quad Receiver on (or close to) conductive, ferrous materials,
damp surfaces (i.e.: walls) or electrical equipment can affect the overall performance of
the Impro Quad Receiver by either blocking, absorbing or interfering with the
transmitted signal from the Quad Transmitter.
Due to the radiation pattern of the integral antenna, it is preferable to install the Impro
Quad Receiver in a high position, with its integrated antenna pointing down. If this is
not possible, then consider using the HRR901-0-1-GB-XX with an external antenna that
meets the requirements of the installation.
