Tools & Test Equipment
No special test equipment is needed when installing the Remote Receiver. Only standard
hand tools are required to install and commission the wireless system. Beldon four core
screened cable is recommended for the connection between Remote Receivers and the Iris+
Receiver. It is also recommended that the Iris+ Engineers Programming Manual is available
when commissioning a remote receiver.
Remote Receiver Positioning
The maximum range between a Remote Receiver and any transmitter is dependant upon the
local environment. A range of up to 250 metres can be obtained although actual range
achieved is determined by site conditions, the quality of the receivers aerial and how well the
system has been installed.
When selecting a site for the receiver, the installing engineer should be aware that the aerial
should be as far as away from electrical / electronic equipment as possible and a minimum of
2 metres from any such equipment. The systems performance will be reduced if the aerial is
closer and will also be reduced by metal objects such as ling cabinets, pipe work, radiators
and air conditioning ducts obstructing the aerial.
Electrical Installation
The Iris+ Receiver and Remote Receivers are supplied with a connection back box and should
be wired as shown on page 14.
The Remote Receiver must NOT be used as a junction box or cable termination point for other
equipment as this will adversely e ect performance of the system. Only those cables needed
to make the Remote Receiver function should be fed into the connection back box.
The Remote Receiver case must be earthed. An earthing tag is provided for this purpose. A
tag is located in the connection back box of the Iris+ Receiver. The Iris+ Receiver and Remote
Receivers require a 12Vdc supply. The 0V line should NOT be connected to the same point as
the earth case.
Ensure that the END OF BUS jumper is made on the rst and last receiver in the wiring daisy
chain (See page 4 for further details). The end of bus jumper can be found on the 2411 PCB,
located at the rear of the Iris+ and Remote Receivers door assembly. The jumper is located
top centre of the PCB.
The RS485 port is used as the Remote Receiver Bus. The maximum overall cable run is 1000
metres.
