3. Checking and Maintaining
We recommend that your alarm system is checked directly after installation and then weekly.
Check that the green mains power indicator is on (if this is off, check circuit breaker, fuses and wiring etc).
3.1 Ei420 connected to an Ei260ENRC Series CO Alarm
Check the RadioLINK communications by pressing the test/hush button on the CO alarm for up to 20 seconds. The horn will sound and the indicator light on the Ei420 should change to red continuously for about 3.5 seconds. This indicates that a RadioLINK message has been sent. All other RadioLINK alarms should now sound. Release the test button. The CO alarm should cease and you should then be able to hear the other alarms sounding in the distance before they also cease. (If any of the other alarms do not sound, see Section 4 - Troubleshooting RF Link)
3.2 Ei420 used as a Repeater
If the Ei420 was installed to strengthen the signal to an alarm (that was previously not receiving a signal), then check the RadioLINK communications, by pressing and holding the test/hush button on this alarm for up to 20 seconds. All other RadioLINK alarms should now sound. This check should be repeated on all RadioLINK units within the system.
3.3 Checking rechargeable
It is important to check that the rechargeable
(i) Disconnect the mains power supply from the Ei420
(ii)Check that the green light is not flashing red once every 10 seconds. (If it is, this indicates that the rechargeable cells are depleted. Remove the cover and check that the rechargeable cell ‘on/off’ switch is in the “ON position - see Figure 3.
(iii)Now check the operation as outlined in 3.1 and 3.2 above.
(iv)
End of Life
After 10 years the Ei420 must be replaced (see “Replace By’ date on the side of the Ei420).
button down until the green light on the Ei420 has illuminated red twice, for 3.5 seconds each time (this could take up to 20 seconds).
If using the Ei420 as a Repeater
Check all Alarms and accessories respond correctly when button tested. Check that the green light on the Ei420 turns red for a few seconds when RF messages are being relayed.

(ii)Add another Ei420 as a Repeater.
(iii)Change the position of the flexible antenna (see Figure 6) by moving it outside the housing and changing it to a horizontal or vertical position. To do this, use a sharp knife and carefully add a notch in the side to allow the antenna to be brought out.
(iv)
Rotating and/or relocating the unit may move it out of the range of existing units even though it may have already been House Coded correctly in the system. It is therefore important to check that all alarms 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 (press and hold the House Code switch on for about 6 seconds until the relevant light comes on and then flashes slowly). Immediately release the switch and the light should stop flashing. Then House Code all units again in their final positions as indicated above. The RadioLINK interconnection should then be
Check all Alarms and accessories respond correctly when button tested. Check that the green light on the Ei420 turns red for a few seconds when RF messages are being relayed.
(i)Radio equipment, such as the Ei420, should be tested 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.
(ii)Receivers may be blocked by radio signals occurring on or near their operating frequencies, regardless of the House Coding.
The Ei420 has been tested to EN 300
(i)
(ii)Increase the distance between the Ei420 and the device being affected.
(iii)Connect the device being affected to a mains outlet on a circuit different from the one that supplies the Ei420.
(iv)Consult the supplier or an experienced radio/television technician.
6. GettingYour Ei420 Serviced
If your Ei420 fails to work after your have carefully read all the instructions, checked that the unit has been installed correctly, and is receiving AC power (green light on) contact Customer Assistance at the nearest address given at the end of this leaflet. If it needs to be returned for repair or replacement, open the cover and turn off the rechargeable cells slide switch (see Figure 3). Put the unit in a padded box and send it to “Customer Assistance and Information” at the nearest address given on the unit or in this leaflet. State the nature of the fault, where the unit was purchased and the date of purchase.
7. Five Year Guarantee
Ei Electronics, guarantees this unit for five years from date of purchase against any defects that are due to faulty materials or workmanship. This guarantee only applies to normal conditions of use and service, and does not include damage
with the problem clearly stated. (see “Getting Your Ei420 Serviced”). We shall at our discretion repair or replace the faulty unit.
