Signal Strength Table (RSSI Table)
RSSI is an abbreviation being used in RF terminology. It stands for Received Signal Strength Indicator.
It is a measurement value of the current strength of the radio signals received by the device. This value
is directly related to the distance between the receiver and the transmitter and also to the other
environmental factors. It represents the signal strength that a device has while communicating with a
coordinator or a router.
In this table, the meanings of the RSSI values shown in the device list are shown. It must be observed
that the RSSI values remain within the limits shown in this table before a device is physically placed in
a location. Low signal strength will lead to an unhealthy communication and a low battery life.

3.
Connect the network cable to the “Network Terminal” for
supply and panel communication.
4.
Set the starting address to be shown on the addressed panel from “Addressing” screen
.
5.
Set the number of devices to be
available on the wireless system from “Number of Devices”
screen.
6.
Set PAN from “Set PAN” screen for setting up the wireless system
.
7.
Turn on the connection permission from the “Connection Permission” screen for adding
devices to the wireless system (for connecting devices to PAN).
8.
Make sure that the wireless devices are connected to PAN in the manner described in the
installation & user manual of each device.
Example: Install the batteries of the wireless detector and verify that the device has started by
observing the red and green LEDs lighting respectively. Then, press the
“A”
Connection Button
for
“5”
seconds and start the connection operation. This operation takes approximately
