INSTALLATION
For specific information regarding sounders spacing, placement and special
applications refer to your specific national standards.
In order to install the device, mount the back box to the wall using screws, the
sounder can then be clipped onto the back box.
Preferably, the device should be installed away from metallic objects, doors, and
power lines, as they can cause the communication distance to drop. It is also
important to avoid installing the device near electronic and computer equipment in
order to protect it from potential electromagnetic interference.
Before clipping the sounder onto the back box set the sounder tone and volume
(using the DIP-switches).

INDICATION
The device has a LED which indicates its state according to the following:
TESTING
To test the device, activate an alarm condition on the system via a call-point or fire
sensor. The sounder should activate with the selected tone and volume.
To stop the test silence and reset the control panel.
АNALOG DATA
The device provides the translator module with analog data about air temperature
and voltage levels on its batteries. This information can be viewed in the “Ekho
Configiurator” software.
By analyzing the voltage levels, you can manage maintenance procedures and
predict when you will have to replace the batteries.
WARNINGS & LIMITATIONS
Devices use high quality electronic components and plastic materials that are highly
resistant to environmental deterioration. However, after 10 years continuous
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 recognized
fire engineering standards. Appropriate Risk Assessment should be carried out
initially to determine correct design criteria and updated periodically.

WARRANTY
All devices are covered by a 3-year limited warranty (does not apply to batteries).
The warranty is voided by mechanical or electrical damage caused by incorrect
handling or usage. Product must be returned via an authorized supplier for repair
or replacement along with full information on the identified problem.
BATTERY REPLACEMENT
When a battery requires replacement, both batteries must be changed
together.
a. Open the case of the device.
b. Remove the batteries.
c. Insert the new batteries as detailed in the installation manual above –take
care to observe + / - polarity.
d. Close the case of the device.
e. Test the device in accordance with the manufacturer’s instructions.
It is recommended to change both batteries after 10 years of operation regardless
of their indicated discharge level.
To replace the batteries, use Panasonic CR123A (primary and secondary batteries)
or other with similar characteristics. The batteries must meet the following
standards: UL 1642 lithium batteries, UL certified at www.ul.com or IEC 60086-4
Primary batteries, Part 4: Safety of lithium batteries.
The remaining shelf time of the new batteries must be not less than 8 years.
Failure to observe these instructions will void the device warranty and any liabilities.
CAUTION
- Replacement of a batteries must be of the same type.
- Do not expose used batteries to fire, hot ovens, or mechanical crushing/
cutting as this can result in an explosion.
- Exposing batteries to extremely high environmental temperatures can result
in explosion or the leakage of flammable liquid or gas.
- A battery subjected to extremely low air pressure may result in an explosion or
the leakage of flammable liquid or gas.
DISPOSAL
- Follow local regulations regarding disposal of the batteries
