GENERAL DESCRIPTION
EK-WL8-HS/AU is a wireless 2-in-1 device
equipped with a heat detector and a sounder.
The device analyzes physical factors associated
with fire and the way these factors change
through time. An alarm signal is generated when
the air temperature exceeds a threshold value or
starts rising at a certain speed. The signal
travels through repeaters to the translator
module which then informs the main control
about the emergency.
The thermal sensor is A1R type.
The device is supplied with a mounting kit.
The product complies with the requirements of the AS ISO 7240.5 and AS ISO
7240.25 standards.
FEATURES
•Bi-directional wireless communication
•Intelligent algorithms
•Sound synchronization with other sounders in the system
•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 in the system.
Please refer to the translator manual for full instructions on how to add a child
device to the system. The device can also be initialized using the “Streletz-
Wizard” software.
INSTALLATION
In order to install the device on the ceiling, you
need to mount the base and then screw the
device into it.
Preferably, the device should be installed at a
certain distance 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
electronics and computer equipment in order to
protect it from potential electromagnetic interference.
INDICATION
The device has an LED which indicates its state according to the following rules.

TESTING
A test alarm can be activated with a magnet, by
holding it for 1 second near the area on the
opposite side of the marks on the detector’s base.
ANALOG DATA
The device provides the translator module with analog data about the current air
temperature and voltage levels on its batteries. This information can be viewed in
the “Streletz-Wizard” software.
By analyzing the voltage levels, you can manage your 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.
SOUNDER

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 5-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 detector 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 detector into the base.
e. Test the detector in accordance with the manufacturer’s instructions.
It is recommended to change both batteries after 10 years of operation despite 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 battery with an incorrect type can defeat a safeguard (for
example, in the case of some lithium battery types).
- Disposal of a battery into fire or a hot oven, or mechanically crushing or
cutting of a battery can result in an explosion.
- Leaving a battery in an extremely high temperature surrounding
environment can result in an 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
