(ii) Ensure that there is an Alarm/Base set as a "Repeater" within a
few metres of the Ei408. If Ei168RC RadioLINK Bases are being
used, they are set as "Repeaters" as standard and so an additional
base (with alarm) may need to be installed. If Ei405 and/or Ei405TY
RadioLINK Smoke Alarms are being used, set the alarm that is
closest to the Ei408 into "Repeater" mode (see individual instruction
leaflet).
(iii) There are a number of reasons why the radio signals may not
reach all the RadioLINK units in your system (see Section 5 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 units 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 (see their respective use and care instructions).
Then House Code all units again in their final positions. The radio
interconnection should then be checked again.
Clearing the House Codes:
If it is necessary at some stage to clear the House Codes on the
Ei408.
• Remove the front plate of the Ei408 from the back-box.
• Slide the battery switch off. Wait 5 seconds and then slide switch
back on.
• Press and hold the House Code button for approx 6 seconds, until
the red light turns on, then flashes slowly. Release the button and the
red light will go out.
• Re-fit the front plate to the back-box.
Note: clearing the House Codes will reset the Ei408 to the original
factory settings. It will now only communicate with un-coded units
(see instruction leaflets for information on how to un-code other
RadioLINK devices).
5. 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 Ei408, should be tested regularly 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.
(ii) Receivers may be blocked by radio signals occurring on or near
their operating frequencies, regardless of the House Coding.
The Ei408 has been tested to EN 300 220-1 V1.3.1 (2000-09) in
accordance with the requirements of EN 300 220V1.1.1 (2000-09).
These tests are designed to provide reasonable protection against
harmful interference in residential installations. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio and television reception.
However, there is no guarantee that interference will not occur in a
particular installation. Interference from the Smoke Alarm system can
be identified by turning the whole system off. To turn off the Ei408
remove the front plate and slide the yellow battery switch to the “off”
position (see Figure 2). Refer to the instructions supplied with the
other products used for information on these. The user is encouraged
to eliminate the interference by one or more of the following
measures:
(i) Re-locate the unit.
(ii) Increase the distance between the Ei408 and the device being
affected.
(iii) Consult the supplier or an experienced radio/television technician.
6. END OF LIFE
The Ei408 is designed to last 10 years in normal use. However the
unit must be replaced if:
1. The light on the front plate does not flash green every 40 seconds.
2. The unit is over 10 years old (see “REPLACE BY” label on the side
of the unit).
3. If during checking and testing, it fails to operate.
4. If the light on the front plate is flashing amber every 9 seconds
(indicating the long life battery is depleted).
The Ei408 must be powered off before disposing or recycling in
accordance with the directive 2002/96/EC on waste electrical &
electronic equipment (WEEE).
7. GETTING YOUR Ei408 SERVICED
If your Ei408 fails to work after you have read this leaflet, contact
Customer Assistance at the nearest address given at the end of this
leaflet. If it needs to be returned for repair or replacement put it in a
padded box with the battery disconnected. Slide switch to “off”
position (see Figure 2). Send it to "Customer Assistance and
Information" at the nearest address given on the Ei408 or in this
leaflet. State the nature of the fault, where the unit was purchased and
the date of purchase.
Note: It may be necessary, sometimes, to return additional units (see
individual instruction leaflets) along with the Ei408, if you cannot
establish which is faulty.
8. FIVE YEAR GUARANTEE (Limited)
Ei Electronics guarantees this product against any defects that are
due to faulty material or workmanship for a five year period after the
original date of purchase. This guarantee only applies to normal
conditions of use and service, and does not include damage resulting
from accident, neglect, misuse unauthorised dismantling or
contamination howsoever caused. Excessive operation of the unit will
shorten the battery life and is not covered. If this product has become
defective it must be returned to the nearest address listed in this
leaflet (see "Getting Your Ei408 Serviced") with proof of purchase. If
the product has become defective during the five year guarantee
period we will repair or replace the unit without charge. This
guarantee excludes incidental and consequential damages.
Do not interfere with the product or attempt to tamper with it.
This will invalidate the guarantee
