Limitations Of Radio Communications - Ei Electronics Ei168RC Installation Manual

8. Limitations of R adio Communications
Ei Electronics radio communication systems are very reliable and are tested to high
standards. However, due to their low transmitting power and limited range (required by
regulatory bodies) there are some limitations to be considered:
(i) Receivers may be blocked by radio signals occurring on or near their operating
frequencies, regardless of the House Coding.
(ii) Alarms with RF modules should be tested regularly, at least monthly. This is to
determine whether there are sources of interference preventing communication, that
the radio paths have not been disrupted by moving furniture or renovations, and if so,
to give a warning of these and other faults.
