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 measure:
(i)
(ii)Increase the distance between the Ei428 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 Ei428.
(iv)Consult the supplier or an experienced radio/television technician.
5. Checking & Maintaining Your Smoke Alarm System
We recommend a weekly check is made of your alarm sys- tem. When checking the system also check the Ei428 as fol- lows:
(i)Check that the green mains power indicator is on (if this is off, check circuit breaker fuse, wiring etc.).
(ii)Check the relay switches and that the associated device operate when the system is in alarm (e.g. due to a smoke alarm test button being pressed).
6. Checking RadioLINK Relay Back-Up Cells
It is important to check that the rechargeable cells in the Ei428 Relay module are switched on, charged and capable of pow- ering the system.
(i)Check that the green light is on and that it is not flashing red once every 10 seconds. If it is, this indicates that either the rechargeable cells in the RadioLink Relay are not con- nected or depleted. Disconnect the mains supply. Remove the cover and gently slide the battery slide switch (see fig 1b) into the “on” position. If the green light is still changing to flashing red every 10 seconds, leave it for 2 hours to charge and then
(ii)Disconnect the mains supply. The green light in the Ei428 will turn off. Check the radio link relay as described in section 2, item 13 above. Check the red light does not flash every 10 seconds.
(iii)If everything is satisfactory,
If the relay fails to operate or the red light continues to flash every 10 seconds (even after (i) above) then the unit is defec- tive and must be replaced (see getting your RadioLink Relay serviced as per section 7 below).
End of Life
After 10 years (see date on the side of the RadioLink Relay Base) the Ei428 Relay module must be replaced.
