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 Con-  
trol Panel power switch must be in the off position. This will  
prevent the battery from being totally depleted and possibly  
damaged.  
the Institute of Electrical Engineers (UK). Failure to install this  
system correctly may expose the user to shock or 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 con-  
trol 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.  
Do not turn on until it is fully wired.  
The systems consist of:-

It is preferable to permanently wire the unit into a mains junc-  
tion box. Wire according to the following instructions.  
Warning: First remove the power to the circuit at the distribu-  
tion board. If you are in any doubt about how to do this, get  
help from a qualified electrician.  
Connecting to mains junction box.  
The mains lead wires are colour coded as follows:  
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. This can 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 EI mains powered smoke alarms up  
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.  
brown: live  
blue: neutral  
The wire which is coloured blue must be connected to the ter-  
minal/wire which is marked with the letter N or coloured black.  
The wire which is coloured brown must be connected to the  
terminal/wire which is marked 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. Route all 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

power the system in standby for a week followed by at least 4  
minutes alarm. When the mains fails, the green light is extin-  
guished and the red light flashes rapidly on the control panel to  
indicate it is on battery power. If the battery is starting to be  
fully depleted the red light will go off to indicate the control  
panel is totally unpowered. The battery will last 5 years in nor-  
mal use provided it is not exposed to extremes of temperature  
for prolonged periods, or fully discharged/charged a large  
number of times.  
person, but the internal strobe or auxiliary output do not turn  
on.This lets the user know it is a wake-up call and not a fire.  
Therefore the user needs only one vibration pad under their  
pillow or mattress.  
Triggering Control Panel into Alarm Externally  
A manual fire alarm switch (e.g. a glass break type) can be  
used to get the control panel to turn on the vibration pad and  
strobe light. This is done by connecting the red and yellow  
wires, from the control panel, together, with the switch (or  
volt-free relay isolated contacts). The wires from the switch  
can be connected into the circuit at the pattress terminals.  
Note: This does not cause the smoke alarm to sound.  
We recommend that the functioning of the rechargeable  
battery is checked at least yearly as follows:  
(i) Ensure the control panel has been mains powered for at  
least the previous 20 hours for the battery to charge.  
(ii) Turn off the mains power to the control panel by unplug-  
ging it or switching off the circuit at the distribution board.  
Check that the green light goes off and the red light starts to  
flash.  
(iii) Press the control panel test button for 20 seconds and  
check the strobe flashes brightly and that the pad vibrates  
strongly. Check that the red light continues to flash while the  
test button is pressed. (Cover the strobe light with card to stop  
this dazzling you while looking for the red light). This red light  
flashing indicates that the battery is satisfactory. If the red light  
goes off, or if the strobe is weak, or if the vibration is weak, the  
battery will need to be replaced. Contact the nearest address  
in this leaflet for advice about getting a replacement.  
Adding an EI 158 Smoke Alarm Pattress with relay  
to the system  
The EI 158CS/158P Pattress is used where volt-free relay  
contacts are required to signal to other equipment when one of  
the smoke alarms sense fire. For example the relay can be  
used to signal to a warden call system, or to turn on lights.  
If there are more than two smoke alarms in the system the  
first smoke alarm can be mounted on the opto-isolator pat-  
tress EI 172 as described above. The second smoke alarm, in-  
terconnected to the first, can be mounted on the relay pattress  
EI 158CS / EI 158CSR or EI 158P / EI 158PR. When any  
smoke alarm senses fire the EI 172 pattress will signal the  
control panel into alarm and the EI 158 pattress will switch its  
relay contacts. Note: If both an EI 172 and an EI 158 are being  
used only 6 smoke alarms may be interconnected together on  
the system.  
3. Troubleshooting  
If the units fail any of the tests after installation outlined  
above, the system has probably been incorrectly wired and/or  
all units are not connected. Check all wiring carefully. If the  
green power lights on the smoke alarm and/or the control  
panel are not on, check the wiring to the mains and that the  
mains is not off (e.g. due to a tripped circuit breaker or fuse).  
Check the power switch on the control panel is on.

5. Product Guarantee  
Ei Electronics guarantees this system for one year from the  
date of purchase against any defects that are due to faulty ma-  
terials or workmanship. This guarantee only applies to normal  
conditions of use and service, and does not include damage  
resulting from accident, neglect, misuse, unauthorised dis-  
mantling, or contamination howsoever caused. This guaran-  
tee excludes incidental and consequential damage. If this  
system should become defective within the guarantee period,  
it must be returned to the nearest address in this leaflet. It must  
be carefully packaged with the power switch on the control  
panel in the off position, and with the problem clearly stated  
along with proof of the date of purchase. We shall at our dis-  
cretion repair or replace the unit. Do not interfere with the sys-  
tem or attempt to tamper with it. This will invalidate the  
guarantee, but more importantly may expose the user to  
shock or fire hazards.  
The control panel monitors the wiring to the vibration pad  
and the smoke alarm pattress for faults.  
(i) If the vibration pad is removed or if its wiring is open cir-  
cuit, the control panel will flash the strobe.  
(ii) If the wiring to the smoke alarm pattress is disconnected,  
open circuited or short circuited, the control panel will turn on  
the vibration pad and the strobe light.  
There are no user serviceable parts in this unit. If it is though  
to be defective, it must be returned to the manufacturer for re-  
pair or replacement (see “Product Guarantee” section).  
4. Accessories and other Features  
Control Panel “Aux. Output”  
This guarantee is in addition to your statutory rights as a con-  
sumer.  
The auxiliary output turns on when the control panel is in  
alarm and can supply up to 200 mA at 12 Volts (range 10 to 14  
Volts). (Note: the positive terminal is the pin next to the  
“Clock Input” socket). An Auxiliary Strobe EI 178 is available  
and is supplied with 10 m of cable and a suitable plug. It can be  
located, for example, where it is readily seen during the day  
(e.g. downstairs hallway). An extra Vibration Pad EI 174 is  
available with 2 m of cable and a plug for connecting it to the  
auxiliary socket.
