If momentary relay operation is required, carefully and gently
slide the yellow switch to the “P” position with a small screw-
driver (see figure 1b).  This must be done before the mains
power is connected or the rechargeable cells are activated.

7. Connect the rechargeable cells by carefully and gently slid-
ing the switch to the “on” position See figure 1b.

8. Fit and screw the cover to the module pillars using the two
screws supplied.

9. Connect the mains power to the Ei428 module.  Check the
green light is on.  If a red light flashes every 10 seconds then
switch off the mains power, remove the cover and check that
the battery slide switch is in the “On” position (see figure 1b).
Replace the cover and turn the mains power back on.  If there
is still a problem the rechargeable cells may be depleted,
leave the unit on mains power for 2 hours to charge and test
again. 

10. Press and hold the House Code switch through the hole
in the cover using a small screwdriver, see figure 1a, until the
green light changes to red.  Release the switch and the light
will flash red quickly, a few times.  The red light will then flash
every 5 seconds (this is a dual colour light so the green light
remains on when the red light is off and vice versa).  Similarly,
put all the other RadioLINK units in the property into House
Code Mode (see relevant user instructions) within 15 minutes
(before the timeout period expires).

11. Check that all the RadioLINK units have communicated
with each other by counting the number of times the light
flashes on each unit in turn (the light will flash red on the
Ei428 relay modules, amber on the Ei168 bases and blue on
the Ei405/405TY).  For example, 3 units in the system should
have 3 flashes every 5 seconds, 4 units should have 4 flash-
es and so on (if there is a problem see section 3).  

12. All the units will automatically exit the house code mode
after 15 minutes.  We recommend that you manually exit the
house code mode by pressing and holding the house code
switch, on all units, until the red/amber/blue light (depending
on the unit) turns on.  This reduces the risk of accidentally
house coding your alarms and other components with nearby
systems.

13. Check the RadioLINK communication by pressing the
test/hush button for up to 60 seconds on each alarm.  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).

If an Ei410 is being used, (with the relay in continuous ‘C’ on
mode), check that pressing the test button causes the relay to
switch and that releasing the test button causes the relay to
switch back.
