4. TROUBLE SHOOTING RF
If, when checking the RF interconnection, some of the alarms do not
respond to the Ei408 test (as outlined in section 3), then:
(i) Ensure the Ei408 has been activated correctly and the red light
has come on continuously for 3 seconds and then continues to
flash red every 45 seconds.
(ii) Ensure that there is an Alarm/Base set as a “Repeater” within a
few metres of the Ei408. If Ei168RC RF Bases are being used,
they are set as “Repeaters” as standard and so an additional base
(with alarm) may need to be installed.
(iii) There are a number of reasons why the radio signals may
not reach all the RF 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 RF
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.
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).
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.
