all Alarms should sound. Ensure that the device connected
to the relay contacts operates. After 60 seconds release
the test button – check the device switches off. (If the
continuous/pulse slide switch is in the pulse position,
check the relay just switches on for 5 seconds and then
switches off). All RF devices in the house code system
should be checked similarly.
3. Troubleshooting RadioLINK
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 RF light comes on (this could take up to 40 seconds).
(ii) Re-locate/rotate the units. There are a number of reasons
why the radio link signals may not reach all the RadioLink
Relays in your system (see section on “Limitations of Radio
Frequency Signals”). Try rotating the unit 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 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
factory 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 RadioLink interconnection
should then be re-checked again.
4. Checking & Maintaining Your Smoke Alarm
System
We recommend a weekly check is made of your alarm system.
When checking the system also check the Ei428 as follows:
(i) After 10 years (see date on the side of the RadioLink
Relay Base) the Ei428 Relay module must be replaced.
(ii) Check that the green mains power indicator is on (if this
is off, check circuit breaker fuse, wiring etc.). When the
mains is restored the green light will come on solid.
(iii) The light flashing red every 10 seconds indicates a battery
problem. Check that the slide switch is in the “ON” position
(See fig 1b) and leave the battery to recharge for 2 hours
before checking again. If the unit continues to flash red
every 10 seconds then the unit is defective and must be
replaced, see “Getting your Relay Base Serviced” section.
(iv) Check the relay switches and that the associated device
operates when the system is in alarm (e.g. due to a smoke
alarm test button being pressed).
