Introduction
This leaflet describes the installation of the EI 170 and EI
171 Systems.
Important: Read all instructions before installing. This leaf-
let must be left with the end user after installation.
N.B. If the system is not being used for some time the Control Panel power switch must be in the off position. This will
prevent the battery from being totally depleted and possibly
damaged.
Do not
turn on until it is fully wired.

system correctly may exposetheuser to shockor fire hazards.
Control Panel
The Control Panel should be permanently fixed to the wall
using the screws and plastic plugs enclosed. The screws
should be spaced 114 mm (4.5 in) vertically apart. The top
screw will be 27 mm (1.1 in) below the top surface of the control panel when installed. The screws (large heads) should be
screwed into the wall leaving a gap of approximately 4 mm
(0.15 in) under the head. Fit the keyhole slots on the back of
the control panel over the screw heads and slide the panel
down vertically into position.
The mains adaptor can be plugged into a socket. The socket
must not be used for any other equipment and it must always
be switched on.
It is preferable to permanentlywire the unitinto a mainsjunc
tion box. Wire according to the following instructions.
Warning: First remove the power to the circuit atthe distribu
tion board. If you are in any doubt about how to do this, get
help from a qualified electrician.

1. Location & Installation
The Control Panel should normally be fixed such that the in
ternal strobe light can be seen from the bed and the vibration
pad can be placed under the mattress or pillow. It has to be
powered from the mains (230 VAC) so a suitable power point
or junction box must be available to which it can be perma
nently connected. The Smoke Alarm must be located as de
scribed in the Smoke Alarm instructions supplied. Cable (10
m) is supplied to connect between the Control Panel and the
EI 172 Pattress for the smoke alarm. Thiscan be extended up
to 50 m (20 ohms max.) with suitable low voltage cable if re
quired. The smoke alarm supplied with the system may be in
terconnected with other
to a maximum of 12 smoke alarms in total. Many dwellings re
quire more than one smoke alarm for minimum protection.
See the smoke alarm instruction leaflet for detailed advise on,
interconnection, maintenance etc.
Warning: This mains operated system should be installed
and interconnnected by a qualified electrician in accordance
with the Regulations for Electrical Installations published by
EI mains powered smoke alarms up
Connecting to mains junction box.
The mains lead wires are colour coded as follows:
-
-
-
-
-
-
brown: live
blue: neutral
The wire whichis coloured blue must be connected to the ter
minal/wire which ismarked with the letter N or coloured black.
The wire which is coloured brown must be connected to the
terminal/wire which ismarked with the letter L or coloured red.
The apparatus is not to be earthed, so no connection is to be
made to terminals or wires marked with the letter E, the sym
bol or coloured green or green and yellow.
Bring the low voltage wiring to where the smoke alarm is to
be located. Routeall wires neatly and securely along the walls
and ceilings.
Note: Turning off the power switch on the Control Panel
does not switch off the apparatus from the supply mains. The
switch removes the AC and battery power from the Control

Panel, but the mains transformer remains connected to the
supply mains.
Vibration Pad
Plug the vibration pad into its locking socket on the control
panel. Place the vibration pad under the pillow or mattress. It
is important that the person in the bed can feel the vibration check it is sufficient to wake a person by lying on the bed and
pressing the test button on the control panel - see also “Test
ing your system”. Some mattresses may not transmit suffi
cient vibration, and in these cases it should be fitted under the
pillow. Note: During testing, or in an actual alarm situation,
the pad pulses on and off for greater effect on sleepers.
Mains Smoke Alarm Interface Pattress EI 172
The pattress is used to mount the smoke alarm in its location,
to connect it to the mains and interconnect wires, and to con
nect it to thewires fromthe
tions from the non-isolated mains powered smoke alarms, to
the low voltage control panel wires are through an optoisolator in the
EI 172 for electrical safety).

and slide on to the mounting plate.
Interconnecting Smoke Alarms
A maximum of 12 EI 150/ 151/ 153/ 154/ 155/ 156
Smoke/Heat Alarms may be interconnected to one
unit. When one alarm senses fire all interconnected units will
sound and the control panel will turn on the strobe light and vi
bration pad (See Smoke Alarm instruction leaflet for further
details on
Warning
interconnection wiring).
: Do not connect to any other type of Smoke Alarm.
Doing this maydamage thealarms and could result in a shock
or fire damage.
Note 1: An alarm with battery back-up (i.e.
EI 151/154/156)
will continue to operate during mains failure and will be able to
signal the control panel if they sense fire.
The control panel also has battery back-up, so that it too will
operate during mains failure.
2. Testing your System
EI 172
-
1. Choose the mounting position following the siting instructions in the Smoke Alarm leaflet. Remove the power from the
circuit you plan to use. The HMSO Building Regulations state
that self-contained Smoke Alarms should be permanently
wired to a separately fused circuit at the distribution board.
2. Where the incoming mains and interconnect wires are on
the surface of the ceiling or wall the appropriately sized duct
ing/conduit must be chosen to mate with the unit.
3. The low voltage wiring from the control panel must not be
run in the same conduit as the mains/interconnect wires.
4. Using a sharp knife remove material from the appropriate
knockouts making sure that there is no gap, either where
mated with the ducting/conduit or with the low voltage wires.
There are five knockouts, four on the sides and one on the
rear.
5. Screw the pattress to the surface using the two screws
and plastic plugs supplied.
6. Figure 1 shows the connections. Connect the incoming
live, neutral, and interconnect (from other smoke alarms if
present) to the pre-wired connector block. If an earth wire is
present connect it tothe fourthterminal as shown.The Smoke
Alarm connector plug is alreadywired to the pattress. Connect
the red wire (remove the small piece of insulating tape first)
from the control panel to the terminal marked “R” and the yel
low wire to the terminal marked “Y”. The black and blue wires
from the control panel are not used. They should both be con
nected to the spare terminal for extra strain relief.
7. Bring the connector plug out through the rectangular hole
in the mounting plate, line up the latch with its recess and then
screw the mounting plate on to the box as shown in figure 2
with the screws provided.
After Installation
1. Turn on the AC mains power to the smoke alarm circuit.
Check the continuous green lightis visible on the smoke alarm
cover. The red light behind the test button will flash every 40
seconds.
2. Plug in the control panel mains adaptor (or turn on the AC
-
mains if it is connected to a junction box). Slide the power
switch on the side of the unit to the “on” position. Check the
continuous green light on the control panel cover is visible.
3. Press the test button on the smoke alarm. The smoke
alarm should sound and the red light behind the button will
flash every second. After about 4 seconds the control panel
will start flashing the strobe light and the vibration pad will turn
on. Two people may be needed for this test. Interconnected
smoke alarms (where present) should also be testedin similar
fashion.
4. Press the control panel test button. Check the vibration
pad is on and that the strobe is flashing.
Daily & Weekly Testing
We recommend that you test your system weekly by press
ing all the smoke alarm test buttons and checking that the vi
bration pad and strobe light are operating. Also check at the
same time that the green power lights are visible on both the
smoke alarm(s) and the control panel.
-
Check daily that the vibration pad is in its correct position by
pressing the test button on the control panel.
Periodic Testing of Rechargeable Battery
The rechargeable battery takes about 20 hours to charge
from the control panel when it is first powered up. The panel
then maintains it in the fully charged state by continuous
trickle charge. In the event of a mains failure the battery will
