version and model of Receiver.
169MHz Zoned Network Receiver
INSTALLATION
Network Receivers should be sited in a dry secure area; they are NOT suitable for outdoor locations.
As the fabric and layout of all buildings differ, an RF site survey is recommended for each installation to establish the best
locations. A typical radio range of 75 metres radius can be expected for a Network Receiver with a 1/2 Wave Aerial, see
building plan below with 2 receivers giving full coverage;
Construction materials such as foil backed plasterboard, reinforced concrete or stone walls will reduce range.
Environmental conditions such as high levels of transmission at nearby frequencies or emissions from other electrical
equipment may further reduce range. Clear line-of-sight will give best range.
