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 should 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.

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.

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
Primary batteries, Part 4: Safety of lithium batteries.
The remaining shelf time of the new batteries must be not less than 8 years.
