(iv) Re-locate/rotate the units. There are a number of reasons why the radio link
signals may not reach all the smoke alarms in your system (see section 6 on
Limitations of Radio Frequency Signals ). 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 about 6 seconds until
the amber light comes on and then flashes slowly). Then house code all units again in
their final positions as per section 3 Installation paragraphs 10 - 13. The radio link inter-
connection should then be checked again.
