GENERAL DESCRIPTION
EK-WL8-H is a wireless heat sensor.
The sensor analyses the environmental
temperature in the protected area. An alarm
condition is generated when the temperature
level or the temperature rise exceeds the
threshold. The alarm signal is relayed to the
Control Panel via the connected
translator/expander modules.
The heat sensor is approved with an A1R
classification.
The device is supplied with a mounting kit.
The product complies with the requirements of the AS ISO 7240.5 and AS ISO
7240.25 standards.
FEATURES
•A1R classified
•Bi-directional wireless communication
•Intelligent algorithms
•Tamper switch
•10-year battery life
•Self-optimizing wireless frequency and amplitude algorithms

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”
software.
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 electronic
and computer equipment in order to protect it 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 thermal sensor
fault
Red flashes every 2 seconds

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 heat test tool can also be used, please
follow the instructions to apply heat to the sensor
in the correct way.
ANALOG DATA
The device provides the translator module with analog data about the current air
temperature and voltage levels of its batteries. This information can be viewed in
the “Ekho Configuration” software.
By analyzing the voltage levels, you can manage maintenance procedures and
predict when you will have to replace the batteries. Please refer to the software
manual for full instructions on how to use the program 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
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. 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/
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
