1. INTRODUCTION
The Ei408 is a battery powered RadioLINK Module that accepts an
input from a set of Volt-Free switched contacts (e.g. flow switch
contacts on a sprinkler system).
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.
2. INSTALLATION
It is recommended that you install all other RadioLINK devices that
will form part of the system before installing the Ei408 Module.
Note:
All RadioLINK units should be located in their final
positions before House Coding is carried out.
The Ei408 should not be mounted close to any metal
objects, metal structures or fitted to a metal back-box.
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).
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.
3. Switch on the built-in battery by sliding the yellow battery switch to
the “on” position (see Figure 2).
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
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).
5. Screw the front plate back onto the back-box.
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).
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.
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).
8. Remove the Ei408 from House Code mode by unscrewing the front
plate and then pressing and holding the House Code button until the
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
The Ei408 is an important alarm device and should be tested after
installation and then regularly to ensure correct operation as follows.
a) Check that the light on the front plate flashes green every 40
seconds to show that the battery power is healthy.
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
(once every 20 seconds) for 5 minutes indicating a repeat
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.
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”.)
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).
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).
4. TROUBLE SHOOTING RF LINK
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.
