INTRODUCTION
This user manual covers the following two
products, Zeta ZD-SI-601 (Ionisation) Smoke
Alarm and ZD-SO-601 Toast Proof (Optical)
Smoke Alarm.
Congratulations! You’ve made a wise
investment in an innovative product and
your personal safety. The Zeta smoke
alarms covered by this manual form part
of a new generation of domestic life safety
products from Zeta Alarm Systems. The
Zeta range of products is constantly being
improved and expanded. Please visit www.
zetaalarmsystems.com to find out about the
latest additions to our product range.
IMPORTANT: This user manual
contains important information
regarding the operation of your Zeta smoke
alarm. Ensure you read this user manual fully
before installing and operating the alarm. If
you are installing this smoke alarm for use by
others, you must leave this manual (or a copy
of it) with the end user.
SENSOR TECHNOLOGY
There are two main types of smoke alarm. The
ZD-SI-601 Standard Smoke Alarm uses an
ionisation type sensor to detect the presence
of smoke. Ionisation type smoke alarms are
generally more effective at detecting fast,
flaming fires which consume combustible
materials rapidly and spread fire quickly. The
ZD-SO-601 Toast Proof Smoke Alarm uses an
optical (photoelectric) type sensor which is
more effective at detecting slow burning fires,
which can smoulder for hours before bursting
into flames.
TOAST PROOF = less sensitive to cooking
fumes. (Optical alarms are less prone to
nuisance alarms due to cooking fumes.)
For maximum protection, use both types of
smoke alarms on each level of your home

3
APPLICATION
WARNING: Your Zeta smoke alarm
can be installed into a new build property
as additional protection to an existing smoke
detection system only. It cannot be used
as a substitute for a hard wired system as
required in new build properties. In this
type of property the building regulations
require alarms to be interlinked. You can
obtain further information from your local
fire service or building control department
at your local council offices. These sources
generally provide advice on new builds or
projects that require planning permission.
Your smoke alarm typically meets the minimum
requirements for family living units in existing
buildings, as long as at least one unit is
installed on each floor/level of your property.
In order to achieve the earliest fire warning,
we recommend that a smoke alarm is fitted in
all rooms where the temperature is normally
between 4°C (40°F) and 38°C (100°F). The
type of smoke alarm used in each location
should be appropriate to the environment.
Check the section on ‘Positioning’ to ensure
that the smoke alarm is to be correctly
positioned for the particular dwelling into
which it is intended to be installed.
WARNING: The alarm positions
shown overleaf are based on typical
homes. Construction and layout of individual
dwellings will vary, so this should be regarded
only as a guide. Check with your local fire
station for further guidance.
Multi-family or mixed occupant residence
(Tenancy building, student accommodation)
Your Zeta smoke alarm can also be used in
individual flats and bedsits, providing the
same conditions are met as for a single-family
residence. However, there must already be
a primary fire detection system that meets
regulatory requirements for common areas
such as lobbies and hallways.

NOTE: Kitchens should be covered by a
self contained heat detector.
RECOMMENDED FOR ADDITIONAL
PROTECTION

4
Institutions and Hotels
This includes motels, hospitals, day care
facilities, long-term health care facilities,
boarding houses and dormitories. Your smoke
alarm can be used in individual sleeping/
resident rooms, providing the same conditions
are met as for a single-family residence.
However, there must already be a primary
fire detection system that meets regulatory
requirements for common areas such as
lobbies and hallways. Use of this smoke alarm
in common areas may not provide sufficient
fire warning to residents or meet regulatory
requirements.
This smoke alarm is designed to operate as
standalone smoke alarm.
WARNING: This Zeta smoke alarm
will not communicate with other smoke
alarms or fire alarm systems. It is not intended
as a substitute for a complete alarm system.
Mobile Homes and Caravans
This smoke alarm is suitable for use in mobile
homes and caravans.
Commercial and Industrial Premises
This smoke alarm is not intended for any
non-residential, commercial or industrial
application, nor for any other purpose than
described above.
POSITIONING
Ionisation type smoke alarms are generally
more effective at detecting fast, flaming fires
which consume combustible materials rapidly
and spread fire quickly.
Examples fast flaming fires = Ignited paper,
flaming curtains and oil fires
Optical (Toast Proof) smoke alarms are less
prone to false alarms from cooking fumes, are
therefore suitable for locations near kitchens.
However optical smoke alarms are more
susceptible to nuisance alarms from steam and
should not be located too close to bathrooms
and showers.
Examples of slow smouldering fires = cigarette
on furniture and bedding, overheating
electrical cables.
It is recommended that your Zeta smoke
alarm is NOT to be fitted in the following
locations:
• Bathrooms, shower-rooms, and other very
damp or humid areas, where the moisture
can cause unwanted alarms.
• Kitchens. Kitchens should be protected
with self-contained Heat Alarms, as the
combustion particles from cooking in
kitchens will result in unwanted alarms and
permanent contamination of the smoke
alarm’s sensor.
• In areas where excessive dust or dirt could

5
contaminate the sensing chamber, making
it over sensitive or impairing smoke entry.
• In areas where the ambient temperature
is not controlled and may regularly drift
below 4°C (40°F) or above 38°C (100°F)
e.g. unheated buildings, open attic
spaces.
• Very dirty, dusty or greasy areas.
• In very draughty areas, such as close to
ceiling fans or fresh air vents. Draughts can
blow smoke away from the alarm.
• In insect infested areas. Insects can
clog openings to the sensing chamber,
preventing smoke entry or causing
unwanted alarms.
• Within 30cm (12”) of a uorescent light
fitting which emits electrical ‘noise’ that can
prevent correct alarm operation.
• In wall positions that are more than 30cm
(12”) away from the ceiling (see ‘How to
install your smoke alarm’).
• In ‘dead air’ spaces (see following
diagram).
• Within 30cm (12”) of light ttings or other
ceiling based obstructions.
WARNING: Prolonged exposure to
temperatures outside those stated above
will reduce battery life.

WHAT ARE THE
LIMITATIONS OF MY
SMOKE ALARM?
Your Zeta smoke alarm is designed to alert
you by sounding an alarm when it senses
smoke, i.e. it can only sense smoke and alert
you if smoke reaches it! If a fire develops in
an area remote from the location of the smoke
alarm, such as another room or another level,
smoke may not reach the smoke alarm in
sufficient time or quantity to sense and alert
you to the danger.
We recommend that as a minimum you install
both ionisation and optical smoke alarms on
every floor of your property. For comprehensive
coverage a smoke alarm should also be fitted
in every room.
This smoke alarm cannot be used to provide
primary fire detection in common areas used
by different residents such as blocks of flats
and hotels. The Zeta smoke alarm may not
alarm before a fire causes damage, injury or
death, as the smoke may not reach the smoke
alarm in time. Examples include smoking in
bed and violent gas explosions. This smoke
alarm may not respond in a reasonable
time if it is not installed in the best position,
or if furniture or other obstacles are located
between the smoke alarm and the fire.
WARNING: Your smoke alarm will not
operate without a battery installed. Only
batteries listed on page 14 should be used
and must be changed immediately when the
low battery signal is given or the unit will fail.
Test weekly, read and follow all instructions
or the unit will not operate properly.
Your Zeta smoke alarm will advise you of a
low battery condition by emitting an audible
‘chirp’ every 40 seconds. When this occurs
you must change the battery in the unit within
7 days to maintain correct operation.
IMPORTANT: Smoke alarms are
designed to alert you with an audible
alarm at a level specified by the British
Standard BS EN 14604: 2005. Closed doors,
walls and high ambient noise levels will
reduce this level. Temporary or permanently
impaired hearing may result in the alarm not
being heard. Stereos, traffic and other loud
sources may also prevent the alarm being
heard. Heavy sleepers and residents under
the influence of alcohol or drugs may also
not hear or respond to the alarm. Test and
check that you can hear the alarm in all
circumstances. If in doubt install additional
smoke alarms as required.
WARNING: The Smoke alarm is not
suitable for alerting hearing impaired
residents. We recommend that specially
designed warning systems be installed that
will alert hearing impaired residents.

7
WARNING: The smoke alarm
accompanying this manual employs the
latest technology and is independently tested
as being compliant with all the relevant British
Standards. However, as with any electronic
product it may fail and may not sense all
types of fire within sufficient time to alert you
of the danger and provide adequate time
for your escape. In order to maximise your
level of safety always test your smoke alarm
frequently to ensure it is in full working order.
Your Zeta smoke alarm is only suitable for
use in domestic / residential applications
as covered in this manual. It is not suitable
for commercial or industrial applications.
It is designed to sense smoke and alert
you. It will not sense carbon monoxide,
flames, heat or gas. It will not prevent or
extinguish fires.
This Zeta smoke alarm has a limited life of
10 years and should not be considered as
a substitute for life or property insurance. Like
all electronic equipment, it can wear out or
fail. It should be tested weekly and replaced
immediately in the event of failure, and
replaced every 10 years regardless.
HOW TO INSTALL YOUR
SMOKE ALARM
IMPORTANT: Make sure you have
read and understood this manual before
installing your smoke alarm.
1 Preparation
Attach the mounting plate to a ceiling
or wall. Use the fixing slots on the
mounting plate as a guide when marking
the position of the drill holes. With an
appropriately sized drill, drill the holes and
insert the plastic fixing anchors supplied
(if needed).

2 Install Mounting Plate
Fit the mounting plate to the ceiling or wall
using the screws provided.
If the alarm is to be mounted on a wall,
ensure the mounting plate is aligned correctly.
The mounting plate has an arrow moulded
into the plastic. This indicates the orientation in
which the mounting plate should be installed.
This ensures that when the alarm is fitted the
vents will be central and facing upwards.
2 Install Mounting Plate
3 Install 9V Battery
IMPORTANT: Before installing your
smoke alarm the battery must be removed
from the alarm and the protective wrapper
on the battery should be removed. The
battery should then be refitted. The battery
compartment has been designed to prevent
the battery being inserted incorrectly.
CAUTION: The horn is designed to
be loud to wake you in an emergency.
Avoid placing your ear close to the alarm
when installing battery.
Insert the battery that was provided with
the alarm making sure that the positive and
negative connections are in the correct
position, see diagram. The red LED on the
front should now flash once every 40 seconds
to show the alarm is active.
3 Install 9V Battery
Ensure wrapper is removed

9
NOTE: On rare occasions the
alarm may sound when the battery
is first installed. If this happens, see
Troubleshooting on page 23.
The backing plate has a safety mechanism
which prevents the alarm being installed
without a battery. When the battery is
inserted this safety mechanism is released
meaning that the alarm can be attached to the
backing plate.
4 Fit Your Zeta Smoke Alarm
The alarm will only lock into place in one
particular position. Position the smoke alarm
over the mounting plate lining up the central
vent on the front of the alarm with the ‘X’
moulded into the plastic on the mounting plate
and turn clockwise. After one quarter turn you
should feel the alarm click into place.
5 Test Your Zeta Smoke Alarm
See ‘Alarm Test’ on page 16.
4 Fit Your Zeta Smoke Alarm

OPERATION
Normal condition
The red LED on the front should flash once
every 40 seconds to show the alarm is
active.
Low Battery Condition
IMPORTANT: Your smoke alarm
requires a battery with a sufficient
capacity of power to operate correctly, this
must also be correctly installed.
Should your Zeta smoke alarm enter a low
battery condition, the unit will emit an audible
‘chirp’ once every 40 seconds. When
this occurs you must replace the battery
immediately. Your Zeta smoke alarm will
continue to warn of this low battery condition
for at least 7 days, however, failure to change
the battery after this time would mean your
smoke alarm has insufficient power to alert
you in a real fire situation.
BATTERY REPLACEMENT
IMPORTANT: Only the following
batteries can be used for replacement.
Use of a battery other than those
recommended below may have a detrimental
effect on the detector’s operation. Use of
a lithium (long-life) battery could provide
power for 10 years under normal operating
conditions, meaning there is no need for an
annual battery change.
Carbon-Zinc type:
Eveready Energizer 1222; Gold Peak
1604S (UL).
Alkaline Type
Energizer 522; Duracell MN1604; Duracell
9V Ultra; Energizer 9V Ultra+; Gold Peak
1604A.
Lithium (long life) type
Ultralife U9VL.
aRemove the alarm from its mounting plate
by turning anti-clockwise

bRemove the existing battery and replace
with a new battery, from the list on
previous page, making sure that the
positive and negative connections are in
the correct position. If unsure see diagram
in “3. Install 9v battery” section (Page 12).
cReplace the alarm on its mounting plate,
lining up the large central vent on the front
of the alarm, with the ‘X’ that is moulded
into the plastic on the mounting plate (if
unsure see page 13). Ensure the unit is
securely fitted.
dTest your alarm as explained in the next
section ‘Alarm Test’.
ALARM TEST
aPress the test button in the centre and
release.
bThe unit will emit a loud (85dB at 3
meters) alarm for around 5 seconds and
stop automatically.

12
cThe red LED on your alarm will flash
rapidly during the audible signal.
NOTE: The test button accurately tests
the alarm’s smoke sensing circuit, there
is no need to test your alarm with smoke. If
your smoke alarm fails to give an audible test
signal, please refer immediately to the trouble
shooting guide at the end of this manual.
WARNING: Test your smoke alarm at
least once per week.
ALARM SMART
SILENCE™
DANGER: If your Zeta smoke alarm
emits the full alarm signal and you are not
testing the unit, the smoke alarm is warning
you of a potentially dangerous situation that
requires your immediate attention. Only
use the alarm silence function after making
sure that there is no ongoing fire emergency
situation. Do not block the vents on the alarm
or disable the smoke alarm in any way, as
this will remove your protection. In the event
of a known false alarm such as cooking
fumes your smoke alarm can be silenced in
the following way.
Your smoke alarm features “Smart Silence™”
technology. Smoke alarms can sometimes
react to cooking fumes or other non
emergency situations. Should your alarm
sound the central test button can be used to
temporarily silence the alarm. Your alarm will
automatically return to full sensitivity within
10 minutes.
NOTE: If the level of smoke reaching the
alarm is very high the alarm silence will
be overridden and the alarm will continue to
sound.

13
aPress and release the silence button, the
alarm sound will shortly stop.
bYour alarm will silence and enter into
a reduced sensitivity reset cycle for
approximately 10 minutes.
cDuring the reduced sensitivity reset cycle,
the red LED on your alarm will flash more
rapidly than normal, approximately once
every 10 seconds.
dYour alarm will automatically return to full
sensitivity on completion of the reset cycle
and the red LED will revert to flashing once
every 40 seconds.
DANGER: Never ignore any alarm.
Ignoring the alarm may result in injury
or death. If your smoke alarm activates and
alarms and you are not absolutely certain of
the source of the smoke, get everyone out of
the house immediately.

14
ROUTINE MAINTENANCE
Your Zeta smoke alarm has been designed to
be as maintenance-free as possible, however
in addition to battery maintenance, there are
several things you must do to keep it working
properly.
CAUTION: Your Zeta smoke alarm
is a sealed electrical device and no
attempt should be made to open the case.
Attempting to open the case will invalidate
your Warranty.
Testing
Test your smoke alarm once every week
see section ‘Alarm Test’ on page 16. Any
test failures should be reported to the Zeta
Technical Support Team on page 25.
Cleaning
As a minimum your smoke alarm should be
cleaned once every 3 months using your
vacuum cleaner fitted with the soft brush
attachment.
WARNING: Your Zeta smoke alarm
may false alarm when it is being cleaned
using a vacuum cleaner.
IMPORTANT: Do not use solvents or
cleaners on your Zeta smoke alarm, as
they may cause damage to the sensor or
circuitry. The unit can be wiped with a slightly
damp cloth.
CAUTION: Do not paint the smoke
alarm as this may block the openings
and prevent smoke from entering the sensor.

• Call the Fire brigade on 999 as soon
as possible from outside your house. If
possible use a neighbours phone or call
box rather than a mobile phone (as the
location can be traced from the number if
the line is lost, or the battery runs out for
example).
• Give the address and your name.
• Never go back inside the building until a
member of the fire service has told you it is
safe to do so.
Contact your local Fire Brigade. They will
give you more ideas about how to make your
home safer from fires and how to plan your
family’s escape.
WHAT TO DO IN CASE OF
A FIRE IN YOUR HOME
• If you have made a family escape plan
and practiced it with your family, you have
increased their chances of escaping safely.
Go over the following rules with your
children each time you have fire drills. This
will help everyone remember them in case
of a real emergency.
• Don’t panic, stay calm. Your safe escape
may depend on thinking clearly and
remembering what you have practiced.
• Notify every member in the residence of
the fire.
• Get out of the house as quickly as
possible. Follow a planned escape route.
Do not stop to collect anything or to get
dressed.
• Feel the doors to see if they are hot. If
they are hot, do not open them – use an
alternative escape route.
• Stay close to the oor. Smoke and hot
gases rise.
• Cover your nose and mouth with a cloth
(wet if possible). Take short, shallow
breaths.
• Keep doors and windows closed. Open
them only if you have to in order to
escape.
• Meet at your planned meeting place after
leaving the house. Carry out a head count.

16
REPAIR
DO NOT attempt to repair your Zeta smoke
alarm doing so will invalidate your warranty.
If your smoke alarm is not operating properly,
see the next section ‘Troubleshooting’. If you
cannot solve the problem, please call the
Technical Support Line.
If your Zeta smoke alarm is no longer
under warranty, replace immediately with a
comparable Zeta brand smoke alarm.
