GENERAL DESCRIPTION
•The “wire to wireless” translator module is a device which interfaces the
hard-wired Hochiki Enhanced Systems Protocol (ESP) loop to the Ekho
wireless system. This allows connection of fire detection devices based on
the Ekho wireless communication protocol for monitoring and control.
•The translator is powered directly by the analogue loop and incorprates a
loop short circuit isolator. It is designed to be used with control panels that
implement the Hochiki ESP protocol (Panel compatibility needs to be
checked with the manufacturer).
•The translator is supplied with a mounting kit (an optional back box is avail-
able EK-BOX-01)
•The product complies with the requirements of the AS ISO 7240.17, AS ISO
7240.18 and AS ISO 7240.25 standards.
NOTE
Ekho refers to a family of addressable, wireless, analogue-intelligent devices.
These devices communicate with the translator module wirelessly using the
“Ekho”protocol. This allows the control panel to manage and control wireless
devices as if they were a part of its loop.

Micro USB PORT: Used for updating the firmware with a computer via a mi-
cro-USB cable and for connecting to the “Ekho Configuration” software.
ANTENNA TERMINAL BLOCKS: Can be used to replace the built-in anten-
nas with a third party external antenna. In order to do that, please remove the
existing antennas and insert coaxial cables from the external 868 MHz anten-
nas (connect the central conductor to socket "A").
NOTE: The use of External antenna’s is at the installers/users risk.
TAMPER: When the cover is opened, a "Fault" event is generated, this can
be disabled/enabled via the Ekho Configuration software or the translator
menu.
"ESCAPE/[1]" BUTTON: Used to exit from a menu or a sub-menu if the user
doesn’t want to apply the changes. A second function of this button is to be
used as a digit "1" for the pass code .

ton is to be used as a digit "4" for the pass code.
ISOLATOR indicator: Green LED on: loop is normal and isolator is closed,
yellow LED on: short-circuit on the loop and the isolator is open.
RF indicator: Operates only if the translator is in expander mode. The green
LED indicates that the RF connection with the central node (other translators)
is present, the yellow LED indicates that RF connection with central node is
lost.

INSTALLATION
Avoid installing the translator close to:
-equipment that uses large amounts of electrical current
-large metal objects, structures or metal ceiling structures
-fluorescent lighting fixtures
-computers, and their peripheral and network cabling.
If there are other translators or wireless system expander modules, a distance
of at least 2 meters should be kept between them. In general, all wireless
devices (devices included) should be installed at least 2 meters apart from
each other.
It is recommended to install the translator and expanders at least 2 - 2.5 me-
ters from the floor.
Environmental conditions (temperature, humidity etc.) must be in the ranges
specified at the beginning of this manual.
After having installed the translator, make sure that the translator’s devices
(sensors, call points, etc.) are receiving a good, strong signal (refer to the
individual device manuals) at their installed location.
Install the translator module using screws, fixing point information is shown
below:

FINAL STEPS OF INSTALLATION
Configure the radio system either directly with the translator’s
keyboard/display or with a personal computer. System configuration and pro-
gramming will be described further in this manual.
PROGRAMMING
ACCESS PERMISSION
To access the "Configuration" menu a pass code needs to be entered (default
password- "33333"). It is possible to change the default pass code by entering
the "PSW Change" sub-menu which can be found in "Configuration"/"PSW
Change". To do this you should enter the Current pass code twice and then
the new pass code.
NOTE If the pass code is forgotten a factory reset (This action will erase any
program configuration) of the system will need to be performed. To do this
you should simultaneously press and hold button 1 and 3 and power cycle the
translator. The display will show "Clear all?". Select "Yes", the system will be
reset and the default pass code ("33333") can then be used.

After the ADD command is performed, the translator waits for a device to be
linked, to link a device press the device's "program button" (see the specific
installation manuals of these devices).
After a device has been linked the translator automatically assigns a subse-
quent address to this device. The whole sequence starts from the address
assigned to the translator ("Start Addr" menu option).
2.The following picture describes the DEL ("delete") command procedure,
which can be applied to devices that are already present in the wireless
configuration:

Devices that combine fire sensors and sounders (for example, EK-WL8-OS,
EK-WL8-HS, EK-WL8-OV etc.) occupy two addresses on the ESP loop. The
sounder within these devices will be addressed automatically by adding 127
to the sensor address and then using this number as the sounder address
e.g. 9 (sensor address)+127=136 (sounder address).
When you add a new wireless device, it is added at the end of the list by
default.
When you delete a wireless device, the list shifts up automatically.

"!" at the beginning of the line means that there is a problem with a wireless
device. By using the "State" menu, a user can obtain information about the
general state (alarm/no alarm) and all current fault conditions of the device.
Use the "UP" and "DOWN" buttons to scroll through the faults list.
NOTE After battery replacement in a child device wait at least 5 minutes for
any unexpected fault messages to disappear.
By using the "Control" menu you can turn the device’s LED on or off and ac-
tivate the "RF link Quality" mode. For sensors, it's also possible to generate
an alarm of the system.
In the "RF link Quality" mode, devices indicate their signal strength with the
wireless expander via a flashing LED:
-2 flashes RED –no connection
-1 flash RED –poor signal strength
-1 flash GREEN –good signal strength
-2 flashes GREEN –excellent signal strength
Devices automatically exit the "RF Link Quality" mode after 15 minutes.

WARRANTY
All translators are covered by a 3year limited warranty. The warranty is voided
by mechanical or electrical damage caused by incorrect handling or usage.
Translator must be returned via an authorized supplier for repair or replace-
ment 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 con-
tinuous operation 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 rec-
ognized fire engineering standards. Appropriate Risk Assessment should be
carried out initially to determine correct design criteria and updated periodi-
cally.
