3.1 -Mounting
To establish a healthy communication between the coordinator and the devices, pay attention for
following conditions:
•Choosing a proper communication channel will make the communication between the devices
more stable. Channel selection can be made automatically or manually. If manual selection is
to be made, initially all transmissions in the environment must be detected with the RF-
analyzer and according to this, relatively the most available channel must be preferred. See
programming section for manual channel selection.
•The environmental factors such as high voltage lines, structural elements such as columns and
beams, big metal objects, computers, network lines, other cable lines, etc. may interrupt the
connection between the devices. Devices should be mounted at a distance of at least 2 meters
from such factors.
•There must be at least 2 meters of distance from each wireless device.
•If possible, it must be mounted at least 2 meters high from and parallelly to the ground. The
antenna must remain at an angle of 90 degrees to the ground.
•It must be operated under the proper ambient conditions indicated in technical specifications.
Otherwise, the operating performance will be affected.
•A suitable location must be preferred by considering the communication distance.
Communication distance can be seen in technical specifications.
Figure 1 - Open the Cover
The mounting holes of the module are located under the module cover. To access those, the cover
must be opened by gently pushing through the holes on the right side of the module by using a flathead
screwdriver.
3.1.1 -Cable Holes
The holes must be prepared before wall mounting. For this, holes must be open on the round points
marked on the product housing. Before open the holes, the electronic cards must be removed. The
tabs holding the cards must be pulled gently to remove the cards.
Once the electronic cards are removed, a gentle pressure must be applied behind the point to be
broken open to leave a space underneath by using a thick screwdriver to break open the holes. The
cards can be reinstalled and fixed after this procedure.

3.2 -Antenna Installation
Ensure a proper installation of the antenna in order to provide a good communication between
devices. Otherwise, there may be distance problems and communication performance losses.
There are two superposed cards connected to each other in the module: The upper one is TLPWAN-RF
card, while the other serves as the Flashlink interface and control card. The antenna terminal is located
on the TLPWAN-RF positioned as the lower card. Pass the wire antenna through the antenna input of
the box and fix it on the terminal to the right as shown in the figure. Make sure that the terminal screw
is firmly tightened. An antenna that is not fixed properly may cause performance loss.

2. RSSI value. RSSI, is an abbreviation being used in RF terminology. It stands for Received Signal
Strength Indicator. It is a measurement value of the current power of the radio signal received
by the device. This value is directly related to the distance between the receiver and the
transmitter as well as to other environmental factors. Refer to the “Signal Strength” table for
RSSI value ranges.
3. Battery status is scaled between 0 and 100. “Battery Low” warning will be generated for the
devices having a battery status less than 25%.
4. PER is an abbreviation being used in the communication terminology. It stands for Packet Error
Ratio. It indicates the ratio of the number of erroneous packets sent by the device from the
beginning to the total number of packets sent. Distance and environmental factors are the
mains reasons of data transmission failures. Initially the RSSI values are checked on the devices
having high PER values. In case the RSSI values are within normal limits the device is removed
from its place and taken to a point that is close to the coordinator and the change in PER value
is observed. Device battery is taken out and installed back again after a while for resetting the
PER value or it can be reset by using the “Reset PER” option from the device menu. If the PER
value still continues to increase the RF intensity in the environment must be checked. In such
case, the PAN might have been setup on a wrong channel or other PANs may be taking too
much space on this channel.
5. HW indicates the hardware version.
6. SW indicates the software version.
7. Ping time, indicates the frequency that the devices will communicate with the connected
coordinator/router. A shorter ping time means that the coordinator will communicate with
the device faster and that reduces battery life. In order to adjust ping time, press FORWARD
on the menu selected to proceed to the ping time adjustment page. More detailed information
about ping time can be found under “Ping Time” topic.
8. Reset PER is used for resetting the PER value of the device selected. Menu usage is explained
under the “Reset PER” topic under the functions. When this menu is accessed from the device
selected, only the selected device PER value will be reset.
9. “Delete” is selected to deleting this device from the wireless network and the operation is
approved by pressing the FORWARD button. The inscription “Successful” will be displayed on
the screen if the operation is successful while “Unsuccessful” will be displayed otherwise. The
place of the deleted device will be shown blank on the list. The deleted device cannot send
data to the coordinator anymore. It needs to be connected back again.

7-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.
This table shows what the RSSI value shown in the device list means. 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.

8-Quick Installation
This section explains how to quickly set up a wireless system step-by-step. Setup and programming
topics must be read carefully to carry out these operations.
1. Fix the antenna and antenna housing.
2. Mount the module on an appropriate place.
3. Connect the loop cable to the “Loop Terminal” for supply and fire alarm panel communication.
4. Set the starting address to be shown on the addressable 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 to adding devices
to the wireless system (for connecting devices to PAN).
8. Make sure that the wireless devices are connected to PAN as 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
between 20 and 60 seconds. See the “Device connected” inscription on the screen at the end
of connection operation.
9. Once the device connection operations are completed, turn off the connection permission
from the “Connection Permission” screen.
9-Software Update
You may download the software files of all wireless devices under the “Firmware & Software” section
of www.teknim.com web site and carry out the update operation by using “Teknim Updater” software.
