Wireless System Planning
You must determine if NoWire will need repeaters to get the transmitter signals to be received by the
NoWire receiver. For smaller installations you may not need repeaters if the transmitters are within a
few hundred feet of the NoWire receiver or even further if there are few or no obstacles. For larger
spread out installations you will need to determine where repeaters need to be placed. Here is an
example of a multi-family property with marked repeater locations.
8.2.4.1
Determine if repeaters are necessary
To determine if repeaters are necessary you may utilize NoWire with an EN1501 transmitter in fast
mode. By moving the EN1501 transmitter around to your meter locations while transmitting in fast
mode you may read the transmitter signal level to determine first if it is seen by NoWire and, if so, is the
signal level strong enough.
•
Locate NoWire where it will be installed and apply power.
•
Using the setup menus assign an EN1501 transmitter to a wireless input point if not already
assigned.
•
Open the EN1501 case and press the tamper spring down 3 times within 10 seconds. This will
put it in fast mode and transmit once every minute. The transmitter will stay in fast mode for 3
days, or until the reset button is pressed. NoWire will display a status code of “F” when it
detects the transmitter in fast mode.
•
Locate the transmitter in the desired test location.
•
Using the setup menus for the assigned wireless input point scroll to the “Xmitter Rcvd” setup
screen. This will indicate the date and time it last received a transmission. This will
automatically update with each reception of a message from the transmitter. Stay on this
screen for a few minutes and verify the transmitter message is received every minute.
•
Continue to scroll through the setup menus to the “Xmitr Levels” setup screen. If the Level is
greater than 4 then the signal is strong enough. Note: You may wish to stay on this screen for a
while until the Level value settles to its final value. If it was strong when it was first received
then it may take some time before the true level is established.
