(iii) Extend the flexible antenna from the base housing. To do this, the antenna should
first be removed from its groove in the base of the unit. Remove the breakaway section
in the outer rim and push the antenna in to this groove. For improved signal strength
the antenna can be pushed flat or vertical with respect to the ceiling.
(iv) Re-locate/rotate the units. There are a number of reasons why the radio signals may
not reach all the smoke alarms in your system (see Section on “Limitations of Radio
Communications”). Try rotating the units or re-locating the units (e.g. move them away
from metal surfaces or wiring) as this can significantly improve signal reception.
Rotating and/or relocating the units may move them out of the range of existing
units even though they may have already been House Coded correctly in the system.
It is important therefore to check that all detectors are communicating in their final
installed positions. If units are rotated and/or resited, we recommend that all units are
returned to the factory settings (press and hold the House Code switch on for around
6 seconds until the blue light comes on solidly and then flashes rapidly and stops.
Release the House Code switch). Then House Code all units again in their final positions
as per Section “Installation”. The RadioLINK interconnection should then be checked by
counting the number of flashes and button testing all units.
Note:
The RadioLINK Base will only transmit and repeat alarm RF messages as long as
the Smoke Alarm is detecting fire.
