3. Troubleshooting RF Link
If, when checking the radio link interconnection, some of the Ei428 RadioLINK Relays do not respond to the button test, then:
(i)Ensure you have held the smoke/heat alarm test button down until the light has come on twice, for 3.5 seconds each time (this could take up to 20 seconds).
(ii)Convert one of the RadioLink units (an Ei168 or Ei405) that is centrally located within the house in to a “Repeater” (see relevant user instructions).
(iii)
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/relays are communicating in their final installed positions. If units are rotated and/or resited, we recommend that all units are returned to the fac- tory settings (press and hold the house code switch on for about 6 seconds until the relevant light comes on and then flashes slowly). Then house code all units again in their final positions as indicated above. The radio link interconnection should then be
4. Limitations of Radio 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)Radio equipment, such as the Ei428 RadioLink Relay, should be tested regularly at least weekly. This is to deter- mine 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.
(ii)Receivers may be blocked by radio signals occurring on or near their operating frequencies, regardless of the house coding.
The Ei428 Relay has been tested to EN 300
However, there is no guarantee that interference will not occur
