9. Button test all Alarms in turn and check all the other Alarms are sounding at
the same time. If they are not all communicating see section below "RadioLINK
Troubleshooting".
Additional RadioLINK Alarms can be added to the system at any time. Simply put all
the Alarms into the House Code mode at the same time and again check the number
of blue light flashes on each Alarm.
RadioLINK Troubleshooting
It is imperative that all Alarms in your system communicate with each other. The
number of walls, ceilings and metal objects in the signal path reduces the strength of
the RadioLINK signals between the Alarms. Accordingly, one or more Smoke / Heat
Alarms may have difficulties in communicating to all the other Alarms in the system.
If, when checking the RadioLINK interconnection, some of the Alarms do not
respond to the button test, then you will need to either:
(i) Position another RadioLINK Alarm to act as a 'repeater' (see Interconnection
with RadioLINK Modules below) between the units 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) Remove the module and extend the antenna vertically (or horizontally) as
shown in figure 3. (For maximum RF signal strength orientate all the antennas in
the same direction - see Figure 4).
(iii) rotate / re-locate the units (e.g. move them away from metal surfaces or wiring).
After making these changes to the RF signal path, the RadioLINK signals may still
not be reaching all the Alarms in your system, even though they have already been
House Coded successfully. (see Section on "RadioLINK Limitations").
