as the light illuminates, release the House Code button. The red  
light should start to flash slowly (this indicates that the Ei408 is  
sending out its own unique House Code signal).  
red light illuminates solidly. As soon as it illuminates solidly, release  
the House Code button. The red light should stop flashing. Re-fit the  
front plate back onto the back-box. (Note: The Ei408 will  
automatically exit House Code mode after 15 minutes from it initially  
being put into House Code mode, so this step may not be required).

9. Remove all other RadioLINK devices from House Code mode (see  
individual instruction leaflets).  
All RadioLINK devices will automatically exit House Code mode  
after either 15 or 30 minutes (depending upon device). However, if  
left in House Code mode for these periods, problems could occur if  
a nearby system is being House Coded at the same time (i.e. two  
different systems could become coded together). To prevent this it  
is recommended that all RadioLINK devices in a system are taken  
out of House Code mode once it is determined that they are all  
coded together.

3. CHECKING AND TESTING  
Figure 1  
The Ei408 is an important alarm device and should be tested after  
installation and then regularly to ensure correct operation as follows.  
Terminal Block  
a) Check that the light on the front plate flashes green every 40  
seconds to show that the battery power is healthy.  
Contains vital information on the product’s operation and installation.  
Read and retain carefully. If you are just installing this product the  
manual MUST be given to the householder.  
b) The module should be tested regularly with the external switch  
device (e.g. use a test button on the external device).The light should  
turn red and stay on continuously for 3 seconds and then flashes red

transmission of the alarm signal. (Note: after 5 minutes the RF alarm  
signal ceases and therefore the smoke alarms will stop alarming.This  
prevents the batteries in the Ei408 module from being depleted.  
On receipt of a switched input, the Ei408 sends out a RadioLINK  
alarm signal to trigger all other RadioLINK alarms/bases in the  
system into alarm.  
c) Check that all the RadioLINK units are now in alarm. If everything  
is satisfactory, cancel the test. Check all the RadioLINK units are  
switched off. (If some or all of the alarms have not been activated,  
then the House Coding procedure should be repeated. If there are still  
some problems, see the section on “Troubleshooting”.)

5. Screw the front plate back onto the back-box.  
2. INSTALLATION  
6. As quickly as possible put all other RadioLINK devices that are part  
of the system into House Code mode (see individual instruction  
leaflets). This must be done within 15 minutes of putting the Ei408  
into House Code mode (step 4 above).  
It is recommended that you install all other RadioLINK devices that  
will form part of the system before installing the Ei408 Module.  
Low Battery  
If the light flashes amber every 9 seconds this indicates that the  
batteries are depleted and the Ei408 may no longer be able to send  
an alarm signal. The unit must be removed from its location and  
returned for repair if still with the guarantee period, (see Sections 7 &  
8 for details).  
Note:  
All RadioLINK units should be located in their final  
positions before House Coding is carried out.  
In House Code mode, all the RadioLINK devices will ‘learn’ and  
memorise each others unique House Code. Once House Coded, a  
RadioLINK device will only respond to other RadioLINK devices  
that it has in its memory.  
The Ei408 should not be mounted close to any metal  
objects, metal structures or fitted to a metal back-box.  
If the end of life has been reached (see “REPLACE BY” label on the  
side of the mounting box) dispose according to local guidelines and  
regulations (see label on the inside of unit).  
1. Remove the front plate of the Ei408 by unscrewing the two screws  
and then fix the back-box to a solid surface using the screws  
provided. (Do not recess mount the back-box).  
7. Check that the number of amber light flashes (for RadioLINK  
bases) or blue light flashes (for RadioLINK alarms) corresponds to  
the number of RadioLINK devices in the system. For example, with  
3 Ei168RC RadioLINK bases and 1 Ei408 Module in the system  
there should be 4 amber light flashes on each Ei168RC base  
(Note: The red light flashes from the Ei408 do not relate to the  
number of RadioLINK devices. The flashes simply show that it is  
sending out its own unique House Code).  
4. TROUBLE SHOOTING RF LINK  
2. Neatly run wiring from the Volt-Free switched contacts that will be  
used to trigger the Ei408 through one of the knockouts in the back-  
box and connect to the terminal block as shown in Figure 1.  
If, when checking the RadioLINK interconnection, some of the alarms  
do not respond to the Ei408 test (as outlined in section 3), then:  
(i) Ensure the Ei408 has been activated correctly and the red light has  
come on continuously for 3 seconds and then continues to flash red  
every 20 seconds.  
3. Switch on the built-in battery by sliding the yellow battery switch to  
the “on” position (see Figure 2).  
8. Remove the Ei408 from House Code mode by unscrewing the front  
plate and then pressing and holding the House Code button until the  
4. Press and hold the House Code button (shown in Figure 2) until the  
red light on the front plate of the Ei408 illuminates solidly. As soon
