GENERAL DESCRIPTION
EK-WL8-EXP is an expander module
which is used for transmitting signals
and extending a wireless network. The
expander receives signals from
nearby sensors/modules and trans-
mits these to the translator module,
which then updates the main control
panel about the system events. The
signal can also be transmitted through
a number of expanders. When two or more expanders are used a backup communi-
cation route to the translator module can be created.
The device is supplied with a mounting kit, (an optional back is available EK-BOX-
01)
The product complies with the requirements of the AS ISO 7240.18 and AS ISO
7240.25 standards.

PROGRAMMING
The “Prog.” button on the expander module is used for initializing the expander in the
system. Please refer to the translator manual for full instructions on how to add an
expander to the system. The expander can also be initialized using the “Ekho Con-
figuration” software.

INSTALLATION
Install the expander module using
screws. It is recommended to install
the device at least 2 meters from the
ground.
Ideally, the device should be installed
at a certain distance from metallic ob-
jects, doors, and power lines, as they
can cause the communication dis-
tance to drop. It is also important to
avoid installing the device near elec-
tronics and computer equipment in or-
der to protect them from potential
electromagnetic interference.
To secure the cover, you should
insert the two rivets into the
holes.
To open the cover, remove the two
rivets by gently pulling on the two
cover clips.

NOTE Other terminal blocks that are not described (marked "UNUSED") do not affect

POWER
The expander is powered via an external power supply.
Use any 12V or 24V power supply and connect it to the +/- inputs on the device.
ATTENTION The power supply should have an output current limit of 8A and should
meet the requirements of AS ISO 7240.4. The AC and DC inputs are used for moni-
toring the state of the external power supply (this option should be enabled in EK-
WL8-TRH menu
1
).
The expander measures the voltage levels between “-”and each of the AC/DC in-
puts, a fault event will be generated if the voltage drops below 10.5 V. These inputs
can be directly connected to the open collector outputs on the power supply. In other
cases, you will need to provide power to these inputs through a normally closed fault
relay on the power supply. The AC and DC input monitoring can be disabled via the
translator menu.

Main and Backup power monitor modes should be set "ON"

No communication with the translator or other ex-
panders
If the device is powered on with the cover open, it will activate the “connection quality
evaluation mode”. The connection strength is indicated with the “Link” LED for 15
minutes according to the following:
Excellent (score 5)
-
two green flashes
Good (score 4)
-
one green flash

NOTE
You can check the RF quality in the installed position in two ways: from the transla-
tor's menu or from the Ekho Configuration software.
By using the "Maintenance/Device/Control" option within the translator menu, it is
possible to turn the "RF link Quality" mode on or off. The expander will automatically
exit this mode after 15 minutes.
ANALOG DATA
The expander provides the translator module with analog data regarding the air tem-
perature and RF link quality. This information can be viewed in the “Ekho Configura-
tion” software.
Please refer to the software manual for full instructions on how to use the Ekho Con-
figuration software for system maintenance.
WARRANTY
All expanders are covered by a 3-year limited warranty. The warranty is voided by
mechanical or electrical damage caused by incorrect handling or usage. The ex-
pander must be returned via an authorized supplier for repair or replacement along
with full information on the identified problem.
WARNINGS & LIMITATIONS
Devices use high quality electronic components and plastic materials that are highly
resistant to environmental deterioration. However, after 10 years continuous opera-
tion it is advisable to replace them to reduce the risk of reduced performance caused
by external factors. Ensure the devices are only used with compatible control panels.
Detection systems must be checked, serviced and maintained on a regular basis to
confirm correct operation.
Refer to and follow National Codes of Practice and other internationally recognized
fire engineering standards. Appropriate Risk Assessment should be carried out ini-
tially to determine correct design criteria and updated periodically.
