Warning – Do not directly connect to 220V AC voltage. The New Zealand and
Australian wiring regulations require that any wiring in excess of 32 volts must be
carried out, or be certified by a registered electrician. Consult your local electrical
installer for further guidance.
Switched Inputs for Lockout Function
The inputs (Labelled INP1, INP2 and INP3) are electrically isolated, normally open inputs.
They are connected to suitable mechanical switches, contacts and other closure devices. An
input is active or ON when the input switch is closed and inactive or OFF when the input
switch is open.
Warning – Only mechanical switches or mechanical closure devices should be
connected to the inputs. No external voltage or other electrical source is to be
connected to the inputs.
Antenna Notes
The WP2P/RA2 system is a low power system that is designed specifically for operation in
New Zealand and Australia.
Each WP2P module is supplied with a stub antenna that will provide an operating range of 20
to 50 meters to the RA2, dependent upon terrain and obstacles such as trees and buildings.
All radio systems work most reliably when the path between the radios is clear
“line of sight”.
This needs to be considered when planning longer range systems.
The aerial in the RA2 is contained within the handset. As the range increases, the position
and orientation of the RA2 handheld will influence the range.
An ideal operational height of the RA2 is greater than 300mm off the ground due to a radio
phenomenon
called “ground affect”.
When mounting the WP2P module, ensure the aerial is vertical and as elevated as possible.
A minimum height should be 1m. If this Is not practical, please use an optional externally
mounting aerial which also helps maximise the range.
Warning – Do not operate the WP2P without an antenna attached. Do not
substitute antennas; use only those antennas recommended by your equipment
supplier. Failing to comply with these requirements can damage the WP2P.
Never operate the devices in violation of RSM conditions. AS/NZS 4268:2008 specifies
a maximum EIRP of 1 watt.
Mounting
The WP2P should be mounted onto a flat surface using the Qty 4x M4 fixing holes at
~102mm x 50mm centres. Where the WP2P is to be operated outside or in other adverse site
conditions, then, the WP2P should be housed in an appropriate plastic enclosure.
Note – If the WP2P is to be enclosed in a metal cabinet then an optional external
antenna will be needed. Please contact your equipment supplier for alternative
antenna details and advice.
Adjustments & Settings
There are no user settings or adjustments required.
Radio Address (RA)
All WP2P systems have
a unique “radio address” which is programmed into WP2P modules
during manufacture.
The radio code is represented and specified in the following format “192.168.0.0”, it is a
security measure to prevent unauthorised users.
Note – All WP2P modules in a given system must have the same first three
numbers in their “radio address”. The 4 th
is 0 for the WP2P module and for the
associated RA2(s) is 1, 2,etc. The code is on the rear of WP2P modules and inside the
battery cover of RA2s. The radio code must be stated for purchasing of replacement
modules.
