LIMITATIONS OF RADIO COMMUNICATIONS
This product use a category 3 radio receiver, which is used in cases where loss
of communication cannot cause critical situations, and that it can be avoided
by following the instructions in the user manual. Radio communication can be
disturbed by other systems, especially near the 4G mobile system operating in
neighboring frequencies.
SA703 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:
• Radio transmitter equipment, such as the wireless smoke alarm, should be te-
sted regularly (at least weekly). This is to determine whether there are sources
of interference preventing communication. The radio paths may be disrupted
by moving furniture or renovations, and so regular testing protects against
these and other faults.
• Receivers may be blocked by radio signals occurring on or near their operating
frequencies, regardless of the house coding.
The wireless smoke alarm SA703 has been tested to EN300 220-1 V2.4.1 in
accordance with the requirements of EN300 220-2 V2.4.1. It is designed to
provide reasonable protection against harmful interference in residential instal-
lations. This equipment generates uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause
interference to radio and television reception.
