GENERAL DESCRIPTION
EK-WL8-OH is a wireless multi sensor that in-
corporates a smoke and heat sensor (A1R).
The device analyzes physical factors associated
with fire and the way these factors change
through time. An alarm signal is generated when
the smoke level inside the optical chamber ex-
ceeds a certain threshold or the air temperature
exceeds a threshold value.
The advanced design of the optical chamber
guarantees a very high level of dust protection,
effectively increasing the time between maintenance procedures.
The thermal sensor is A1R type.
The device is supplied with a mounting kit.
The product complies with the requirements of the AS ISO 7240.7, AS ISO 7240.5,
AS ISO 7240.15:2004 and AS ISO 7240.25 standards.
FEATURES
•Bi-directional wireless communication
•Intelligent algorithms
•Tamper switch
•10-year battery life
•Self-optimizing wireless frequency and amplitude algorithms
•Patented smoke chamber design

PROGRAMMING
The “Prog.” button on the device is used for initializing the device on to the system.
Please refer to the translator manual for full instructions on how to add a device to
the system. The device can also be initialized using the “Ekho Configuration” soft-
ware.
INSTALLATION
In order to install the device, the mounting base
should be fixed to the ceiling, the sensor can then be
inserted into the base by rotating the sensor until it
clips into the base
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 electron-
ics and computer equipment in order to protect them
from potential electromagnetic interference.
INDICATION
The device has a LED which indicates its state according to the following:
LED indication
Device’s state
No indication or green flashes
Standby mode
Yellow flashes every 4 seconds
Fault state –low battery or malfunctioning
smoke or thermal sensor
Red flashes every 2 seconds
Fire alarm
When the device is powered up, an automatic calibration process will begin, this
lasts around one minute and is indicated with a red flashing LED.

3 sensitivity options are available, these can be selected only by using the translator
menu or the Ekho configurator software (setting via the control panel will have no
affect and sensor will remain in the selected mode).
TESTING
An alarm test can be performed with a magnet by placing it onto the outside of the
sensor (opposite side to the base alignment marks) the sensor should take around
1 second to activate.
A suitable smoke or heat test tool can also be used, please follow the instructions
to apply smoke/heat to the sensor in the correct way.
ANALOG DATA
The device provides the translator module with analog data about the current smoke
level, air temperature, dust in the chamber and voltage levels of its batteries. This
information can be viewed in the “Ekho Configuration” software.
By analyzing the voltage or dust levels you can manage maintenance procedures
and predict when you will have to replace the batteries or clean the smoke sensor.
Please refer to the software manual for full instructions on how to use the Ekho
Configurator for system maintenance.

WARNINGS & LIMITATIONS
Devices use high quality electronic components and plastic materials that are highly
resistant to environmental deterioration. However, after 10 years continuous oper-
ation 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 con-
trol 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.
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 to-
gether.
a. Remove the sensor from the base.
b. Clip off the battery cover and remove the batteries.
c. Insert the new batteries as detailed in the installation manual above –take
care to observe + / - polarity.
d. Re-fit the battery cover and re-insert the sensor into the base.
e. Test the sensor 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 battery) and Varta
CR2032 (secondary battery) 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/ cut-
ting 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 batterie
