Your SONA
alarm fails to
successfully
learn-in to a
network
• Make sure your alarm is 'unlearned' before trying to learn-in to a network.
Do this by pressing and releasing the learn-in button located on the back
of the alarm, immediately press and hold the learn-in button, during which
the red LED will remain solid. When the LED goes out, release the button.
The LED will ash twice followed by three quick ashes, indicating that it
has successfully been unlearned. You can then follow the learn-in process
as described in 'Wireless Interlink'.
Other interlinked
units fail to
silence when one
unit is silenced
• Interlinked units that have sensed smoke / heat can’t be silenced remotely.
If one or more units remain in alarm, all other interlinked units will emit
their audible warning again within 4 minutes. Vacate property if there is a
re hazard.
WARNING: Storage in low humidity and certain transportation conditions may cause electrostatic
charges to build up in the alarm system housing. Although harmless this may increase the length of time
that the horn sounds upon test button operation. The condition may be cleared by wiping the inside and
outside of the plastic cover with a damp cloth.
If you have any questions about the operation of your alarm, please contact Technical
Support between 9am - 5pm Monday – Friday. Telephone: 0800 171 2009 or e-mail:
