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
”).
