RadioLink RadioLink Ei408 Installation Manual

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.
