1.INTRODUCTION
The Ei408 is a battery powered RF 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 RF alarm signal
to trigger all other RF alarms/bases in the system into alarm.
2. INSTALLATION
It is recommended that you install all other RF devices that will form
part of the system before installing the Ei408 Module.
Note:
All RF 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 RF 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 RF devices will ‘learn’ and memorise
each others unique House Code. Once House Coded, a RF device
will only respond to other RF devices that it has in its memory.
7. Check that the number of amber light flashes (for RF bases) or
blue light flashes (for RF alarms) corresponds to the number of
RF devices in the system. For example, with 3 Ei168RC RF 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 RF 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 RF devices from House Code mode (see
individual instruction leaflets).
All RF 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 RF 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 45 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 RF units are now in alarm. If everything is
satisfactory, cancel the test. Check all the RF 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).
