1General Definitions
TWM-3885 Conventional Wireless Coordinator module is a cabled-wireless access control unit that
allows any conventional fire alarm panel of TLPWAN(1) wireless system to be integrated into the zone
line.
Basically, it allows the TLPWAN based wireless fire detection devices to be connected to the
conventional fire alarm system just like the conventional fire detection devices, and also to be
monitored and controlled against fault and fire situations.
TWM-3885 Conventional Wireless Coordinator module is fed through an external power source and
allows all fire and fault situations on the wireless system to be monitored through it. At the same time,
it performs the sounding and muting functions of the wireless sirens by monitoring the siren outlet of
the conventional fire alarm panel.
(1) TLPWAN (Teknim Low Power Wide Area Network) is a wireless communication protocol
developed by Teknim which allows low power consumption devices on a wider area in a stable
and safe manner by using two-way communication.

3Installation
Under this topic, the installation of TWM-3885 Conventional Wireless Coordinator module will be
explained step by step in details. Please read all steps carefully.
3.1 Mounting
The following articles must be followed carefully in order to provide a good communication with the
devices connected to the coordinator:
•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 current lines, big metal objects, computers, network
lines, other cable lines, etc. that may interrupt the connection with the devices on the wireless
network must be avoided.

•There must be at least 2 meters of distance from other wireless devices.
•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 when all
devices to be communicated are taken into consideration. Communication distance can be
seen in technical specifications.
The mounting holes of the module are located under the module cover. In order 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 through which the cables necessary for module connection will pass must be prepared
before wall mounting. For this purpose, holes must be broken open on the round points marked on
the product housing. Before breaking open the holes, the cards inside of the module must be removed.
The tabs holding the cards must be pulled gently in order to remove the cards.
Once the cards are removed, a gentle pressure must be applied behind the point to be broken open in
a manner to leave a space underneath by using a thick screwdriver in order to break open the holes.
The cards can be reinstalled and fixed after this procedure.
3.1.2 Wall Mounting
Mark the wall according to the 4 screw holes seen below and bore 4 holes on the wall by using a drill
according to the diameters of the wall plugs included in the pack. Insert the wall plugs into the bored
holes and fix the module on the wall by screwing it onto the wall.

3.2 Antenna Installation
TWM-3885 Conventional Wireless Coordinator module is placed in the box with the antenna wire and
antenna housing disassembled. Ensure a good 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 of those 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.
Figure 2 - Antenna Wire Installation
Once the wire antenna is fixed into its place, push the antenna housing into the antenna input tightly
to fix it into its place.

3.3 Supply Connection
Pass the cables from cable holes and strip their ends at a proper length, then make the supply
connections as shown in the following connection diagram. Make sure that the terminal screws are
tightened firmly.

3.4 Zone Alarm Resistor Connection
Zone alarm resistor must always be kept connected to the “Alarm Resistor” terminal. In case of any
alarm situation in the wireless system, the zone alarm resistor gets connected parallelly to the zone

line, and thus the alarm is created on the fire alarm panel. The value of alarm resistor must have been
indicated in the user manual of your fire alarm panel. Teknim conventional fire alarm panels use
“470R” resistors as alarm resistors.

3.5 Zone Line Connection
Conventional wireless coordinator connects to the zone line and thus provides the fire alarm panel to
go into fault and alarm situation. Besides, it checks whether the reset button on the fire alarm panel is
pushed or not by monitoring the voltage on the zone line. There are two types of connection methods
for connecting the conventional wireless coordinator to the conventional zone line.
In case where the coordinator is connected to the middle of the zone line, the line end resistance
connects to another device at the end of the line. The coordinator provides the zone line to be
completed by connecting “Z-IN” and “Z-OUT” ends to each other and also provides the line end
resistance to be connected parallelly to the line. The coordinator, in case of a fault occurrence on the
wireless system, separates the “Z-IN” and “Z-OUT” ends and provides the zone line to become an open
circuit and thus provides the fire alarm panel to go into zone open circuit fault. In such case, since all
conventional devices that remain on the rest of the line will become de-energized, they will become
inoperable.

Figure 6 - Coordinator Zone Connection Diagram 1
In cases where the coordinator is connected to the end of the zone line, the line end resistance gets
directly connected to the necessary terminals as shown in the following connection diagram. The
coordinator, in case of a fault occurrence in the wireless system, separates the “Z-IN” and “Z-OUT”
ends and makes the line end resistance become an open circuit and thus provides the fire alarm panel
to cause an open circuit fault. In such case, since no other devices will remain on the rest of the line,
all devices on the other side of the line will keep on operating.

3.6 Siren Line Connection
Conventional sirens operate according to the voltage applied by the fire alarm panel to the siren line.
Conventional wireless coordinator, follows the siren line and decides whether the wireless siren will
set off or not. At the same time, just like in the zone line, it can check the siren line end resistance and
inform the fire alarm panel about any fault situation regarding the wireless sirens. There are two

connection methods for connecting the conventional wireless coordinator to the conventional siren
line.
In case where the coordinator is connected to the middle of the siren line, the line end resistance
connects to another siren at the end of the line. The coordinator provides the siren line to be
completed by connecting “SIREN-IN” and “SIREN-OUT” ends to each other and also provides the line
end resistance to be connected parallelly to the siren line. The coordinator, in case of a fault occurrence
on the wireless sirens, separates the “SIREN-IN” and “SIREN-OUT” ends and provides the siren line to
become an open circuit and thus provides the fire alarm panel to go into siren open circuit fault. In
such case, since all sirens that remain on the rest of the line will become de-energized, they will
become inoperable.

OUT” ends and makes the line end resistance become an open circuit and thus provides the fire alarm
panel to cause a siren open circuit fault. In such case, since no other sirens will remain on the rest of
the line, all sirens on the other side of the line will keep on operating.
