It is important that all Alarms in your system communicate with each other. The number of walls,
ceilings and metal objects in the signal path will reduce the strength of the SmartLINK signals
between the Alarms. Accordingly, one or more Smoke/Heat/CO Alarms may have difficulties in
communicating to all the other Alarms in the system.
If, when checking the SmartLINK interconnection, some of the Alarms do not respond to the
button test, then you will need to either:
(i) Position another SmartLINK Alarm to act as a ‘repeater’ between the Alarms which are
not communicating and so shorten the path and/or by-pass an obstacle which is blocking
the signal. When the new Alarm is fitted, House Code all Alarms again, as described above.
(ii) rotate / re-locate the Alarms (e.g. move them away from metal surfaces or wiring).
After making these changes to the RF signal path, the SmartLINK signals may still not be
reaching all the Alarms in your system, even though they have already been House Coded
successfully (see Section on “Limitations of Radio Communications”).
It is important to check that all Alarms are communicating in their final installed positions. If
Alarms are rotated, have had their antennas extended and/or re-sited, we would recommend
that all the Alarms are returned to the factory settings and then House Coded again in their
final positions (see above). The SmartLINK interconnection should then be checked again by
button testing all units.
(NB. The SmartLINK module can be returned to the originally factory settings by pressing and
holding the House Code Button until the blue light turns on solidly and then flashes rapidly. This
will take about 7 seconds. This clears the learnt House Codes).
