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 back-up cells
It is important to check that the rechargeable back-up cells in the Ei420 are switched on, charged and capable of powering the unit. We therefore recommend that the rechargeable back-up cells are checked directly after installation and then at least yearly as follows.
(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. Re-fit the cover and reconnect the mains. If it is still flashing red, leave it for 2 hours to charge and then re-check. If it continues to flash red every 10 seconds then it may be defective and must be replaced - see Section 6 - “Getting your Ei420 serviced”)
(iii)Now check the operation as outlined in 3.1 and 3.2 above.
(iv)Re-connect the mains and check the green light comes on
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.
Notch for Antenna
Change the position of the flexible Antenna
Figure 6 - Shows the Antenna moved to the
outside of the Ei420 housing
(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)Re-locate/rotate the units. There are a number of reasons why the RadioLINK signals may not reach all the RadioLink units in your system (see Section 5 - Limitations of Radio Communications). Try rotating the unit or re-locating the unit (e.g. move it away from metal surfaces or wiring) as this can significantly improve signal reception.
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 re-checked.
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 300 220-1 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. If this device does cause such interference, which can be verified by turning the device on and off (remove the mains supply and turn off back up power supply), the user is encouraged to eliminate the interference by one or more of the following:
(i)Re-orientate or re-locate the unit
(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.

8. Technical Specification |
• A dual-purpose module: (1) It can be used to interface an |
Ei260ENRC Series Carbon Monoxide (CO) alarms or |
smoke/heat alarms Ei151TL, Ei154TL, Ei156TLH and |
communicates with all other RadioLINK devices. It must not |
be wired to any other Ei Alarm products (2) It can be used |
as a RadioLINK Repeater module. The unit will receive |
RadioLINK signals and re-transmit them. This can be useful |
as it shortens and provides multiple, RF signal paths to |
strengthen the RadioLINK system in difficult installations. |
Note: the Repeater function only operates after the units are |
House Coded. |
• It is supplied with its own cover. |
• Requires 230V AC Mains Power Supply – constant green |
LED indicates mains power is present. |
• Features built-in tamper proof Rechargeable Lithium back-up |
cells, capable of lasting at least 10 years and powering the unit |
initially for at least 2 months in the event of mains power failure. |
The cell manufacturer endorses a minimum 10-year life |
expectation for the rechargeable cells. The cells are activated |
by operating the battery switch inside the unit. |
• Low back-up warning signal – LED indicator flashes red every |
10 seconds to indicate that the lithium cells are depleted or not |
connected. |
• Radio frequency: 868MHz band in accordance with R&TTE |
Directive 1999/5/EC – this band has been designated for use |
with security products and only allows a 1% duty cycle, so |
continuous transmission and interference from external |
sources is extremely remote, and would be illegal. |
• Up to 12 RadioLINK units can be used in one system. For |
larger systems contact our Technical Service Department for |
guidance. |
• Units are in Factory Code when shipped (they will all |
communicate with each other). They must be ‘House Coded’ to |
eliminate the risk of adjacent properties communicating with |
each other. After house coding they will only communicate with |
other RadioLINK units coded at the same time. |
• House Code: operate the ‘House Code’ switch on all |
RadioLINK units in the system – see the instructions |
supplied with the other RadioLINK units being used. On the |
Ei420, the green LED on the cover will change to red and |
flash slowly: this indicates that it will receive the unique |
•Clearing House Codes: The House Codes memorised can be cleared by pressing and holding the House Code switch on for about 6 seconds. The red light will come on solidly, then flash rapidly. Immediately release the House Code switch. The Ei420 will now be in the default Factory Code.
•To de-activate the Repeater function: The Repeater function of the Ei420 can only be de-activated if it is wired to an Ei260ENRC Series CO alarm. To de-activate, press and hold the test button on the CO alarm until it sounds and the indicator light on the Ei420 illuminates red. Immediately (while the red light is still on) press and hold the House Code switch with a small screwdriver until the red light starts to flash slowly. Immediately release the switch.
The red light will flash slowly a total of four times and then stop. This indicates that the Repeater function has been de- activated on this unit.
If it is necessary to re-activate the Repeater function, simply follow the same steps for de-activating. The red light will flash slowly a total of sixteen times (instead of four) after the last step is completed.
