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 the green light changes to red 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.
11. House code all other RF Alarms and devices in the
system. Consult the instruction manuals on how to house
code the Alarms and devices. It is essential that each
individual Alarm/device is put into House Code mode in
its final location.
12. Check the number of flashes on the Ei428 and on every
other device. They should correspond to the total number
of devices in your system. A system with 3 Alarms and 1
Ei428 will result in 4 flashes. It may take up to 10 minutes
before all 4 flashes are seen.
The flash pattern will repeat every 5 to 10 seconds
while the Ei428 remains in house code mode. If it fails
to flash the correct number of times, then consult the
“Troubleshooting” section of this instruction manual. To
complete the commissioning, the RF system must exit
House Code mode.
13. The Ei428 will automatically exit House code mode after
30 minutes. Other devices may exit after only 15 minutes.
Once coded, the system will not communicate with any
other RF Alarms and devices outside of the house coded
group.
To manually exit House Code mode, press the House
Code button again on the Ei428 until the RF indicator
lights up red, then release. This will send a signal to all the
other RF Alarms and devices to exit House Code mode.
After a short period, the red light will turn off and the
system will return to standby mode. Depending on the
number of RF Alarms and devices in the system this
period could vary from 5 to 20 seconds.
Note: Not all devices are able to receive the Exit House
Code mode signal from another device. If some devices
continue to flash amber / red, please consult their
instruction manual to manually exit house code mode.
Check that the RF indicators have stopped flashing on
all devices.
14. To check the system, press the Test button for up to 60
seconds on any house coded Alarm. After a few seconds
