We recommend a monthly check of your Alarm system.

When checking the system also check the Relay Base as follows:
1.  Check that the green LED power indicator is lit on the Alarm 

that is electrically connected to the Relay Base. If it is off, check 

the circuit breaker fuse, wiring, etc.. when the mains power is 

restored, the green LED will come on solid.

2.  Press the Alarm Test Button and check that:

 

a. The relay switches and 

 

b. The auxiliary device behaves as expected

End of Life

After 10 years (see date label on the side of the Relay Base) the 

Relay Base must be replaced.

It is important to check that the rechargeable cells in the Ei128RBU 

are switched on, charged and capable of switching the relay contacts. 

This should be done after installation and then at least annualy.

1. Disconnect the mains supply.

2. Check the relay as described in section 6.

3. If everything is satisfactory, re-connect the mains.

If the relay fails to operate, then the unit is defective and must be 

replaced (see section 8).

If, within the guarantee period, your Relay Base fails to work after 

your have carefully read all the instructions, checked that the unit 

has been installed correctly, and is receiving AC power, then 

contact us at the nearest address given at the end of this manual.  
If you are advised to return your Relay Base, please ensure that it 

is placed in a padded box, that the slide switch for the rechargeable 

cells is on the OFF position (Ei128RBU only) and include the proof 

of purchase and a note stating the nature of the fault.
