in extreme cases, interfere with these signals,
preventing the Warning Handset from reacting to
an alarm condition.
The Warning Handset monitors signals in the
area to check if this is likely to be a problem. If
interference is detected, the “signal failure” LED
flashes yellow once per minute and the handset
will chirp once per minute as a warning.
If this warning is given, try moving the Warning
Handset to a different position in the room or
move nearby electronic equipment out of the way.
If this doesn’t cure the problem, try switching off
different items of electronic equipment until the
cause is found.
WARNING
: Do not switch off or disable any life
critical or safety equipment.

System Integrity Check
It is important that, when any changes are made
to the system or your home, you check that all
the elements of the Wi-Safe system are still
communicating. When any of the following occur,
check the communication between all the alarms
in the system and the Warning Handset(s). See
Section 4 ‘Testing’ on page 14.
• Changing the battery in the Handset
• Changing the battery in any alarm in the
system
• Changing the layout of your house (ie.
structural changes, moving large items of
furniture, wiring changes, major decorative
alterations, adding large metal constructions)
• Installation of electronic equipment
