Cautions
ELECTRICAL HAZARD: Disconnect power from equipment prior to making any
internal adjustments. Installation and service should only be performed by qualified
personnel.
PRODUCT LIMITATIONS: This smoke alarm does not detect gas, heat or flame,
and should not be covered with a guard or similar obstructing item.
This smoke alarm may not alert people who are hearing impaired. It is strongly recommended
that the special-purpose smoke alarms using visual or vibrating alerting devices, should be
installed for these occupants.
This smoke alarm may not be effective in fires where smoke is prevented from reaching the
device (eg where intermediate doors are closed), where the fire grows so rapidly that the
egress path is blocked (even when correctly located), and where the fire is intimate to a
person (eg where a victim's clothes catch fire).
SLEEPING OCCUPANTS: Studies have shown that smoke alarms may not awaken
all sleeping occupants, and it is the responsibility of individuals in the household that
are capable of assisting other to provide assistance to those who may be awakened by the
alarm sound, or to those who may be incapable of safely evacuating the area unassisted.
INSTALLATION LIMITATIONS This product is designed for use in a single
residential unit, such as a family home or apartment. It should only be used in
lobbies, hallways, basements etc. if interconnected with other compatible smoke or
heat alarms. Smoke alarms, located outside the dwelling may not provide early warning to
occupants.
This product is not designed for use in non-residential buildings. Non-residential buildings
require special fire detection and alarm systems. This product alone is not a suitable
substitute for a fire detection system installed in places of work or where people sleep on a
temporary basis, such as hotels or motels, dormitories, hospitals, nursing homes or group
homes of any kind, even if they were once dwellings. Please refer to local regulations for fire
detection and alarm system requirements.
Features
ZT-MS AC/DC smoke alarms provide smoke detection and alarm functions
within a single unit. Advanced electronics in conjunction with a photoelectric
smoke sensing chamber provide early detection of smoke and high immunity
against unwanted alarms.
ZT-MS AC/DC smoke alarms are mains powered, with battery backup, suitable
for general residential applications. ZT-MS AC/DC smoke alarms provide home
owners and installers with an easy-to-install, premium solution for life safety and
property protection applications.
Audible and Visual Alarm Indicators
When operating normally, a green LED in the Test button illuminate. When
smoke is detected, an internal sounder will activate to alert occupants, and a
red LED will flash rapidly. The sounder is a loud, pulsating alarm.
Test Button
Pressing and holding the Test button for 3 s will activate the smoke alarm to
check its operation. The alarm will sound and the red LED will flash rapidly.
Releasing the test button will return the unit to normal operation.
Low Battery
When the battery is depleted, the smoke alarm will emit a short audible signal
every 48 s for at least 30 days, while the red LED flashes simultaneously. When
the Low Battery signal is given, change the battery without delay.
Smoke chamber fault
When the smoke chamber is degraded or contaminated over a limit, the smoke
alarm will emit two short audible signals every 48 s, while the red LED not
flashes simultaneously. When the smoke chamber fault is given, try vacuum the
product on the outer surface, especially the smoke inlet, to remove dirt. If the
condition persists, return the product for service.
Hush Button
Pressing the Hush button will reduce the sensitivity of the smoke alarm for
approximately 10 min. The Hush button should only be used after the cause of
the alarm is known (such as normal cooking fumes). The Hush feature allows
time for the smoke to clear. During the hush time, the red LED will flash once
every 6 s. After the Hush time has expired, the smoke alarm will return to
normal sensitivity. If smoke is still present in the unit, the alarm will re-activate.
The Hush feature can be used repeatedly.
Under hush mode, press the hush button again will return the unit to normal
operation.
Alarm Memory
Alarm Memory feature allows easy identification of any unit that has previously
been in the Alarm condition. If a unit enters the Alarm condition and
subsequently returns to the Normal condition, the Alarm Memory is set. Initially,
the red LED will flash three times every 48 s. In order to preserve battery power,
this visual indication will stop after 24 hours and the unit will return to normal
operation.
If the Alarm Memory is active, pressing and releasing the Test/Hush button
resets the Alarm Memory with 3 short beeps.
Interconnection Terminals
Interconnected smoke alarms will activate sounders on all units if any smoke
alarm detects smoke. In this case, only the smoke alarm(s) that detected smoke
will flash the red LED indicator. This allows the home owner to quickly locate the
cause of the alarm. Up to 24 units can be interconnected as long as the cabling
is less than 250 m in length.

Location Selection in Homes and Apartments
WARNING: Location and number of smoke alarms may be specified in
relevant regulations. Where these do not exist, the requirements of
NFPA 72 can be used. For your information, the National Fire Alarm Code,
NFPA, reads as follows.
11.5.1 *Required Detection.
*Where required by applicable laws, codes, or standards for a specific type of occupancy,
approved single- and multiple-station smoke alarms shall be installed as follows:
(1) *In all sleeping rooms and guest rooms
(2) *Outside of each separate dwelling unit sleeping area, within 6.4 m (21 ft.) of any door
to a sleeping room, the distance measured along a path of travel
(3) On every level of a dwelling unit, including basements
(4) On every level of a residential board and care occupancy (small facility), including
basements and excluding crawl spaces and unfinished attics
(5) *In the living area(s) of a guest suite
(6) In the living area(s) of a residential board and care occupancy
For complete coverage, smoke alarms should be installed in all rooms, halls,
storage areas, basements, and attics in the dwelling. The minimum coverage
is one smoke alarm on each floor and one outside each sleeping area. Please
use the following location guide.
Single Storey Dwellings
Install a smoke alarm in the hallway outside every separate bedroom area, as
shown in Fig. 1 a). Two smoke alarms should be installed in dwellings with two

Fig. 2 – Multi-storey dwelling
Enhanced Safety
To improve early detection performance and safe evacuation, consider
installing additional smoke alarms as follows.
•At least of two smoke alarms.
•Inside every bedroom.
•At both ends of a bedroom hallway if the hallway is more than 12 m.
•Inside every room where one sleeps with the door partly or completely
closed, since smoke could be blocked by the closed door, and a hallway
alarm may not wake up the sleeper if the door is closed.
•At the bottom of the basement stairwell.
•Second-floor smoke alarms at the top of the first-to-second floor stairwell.
•In your living room, dining room, family room, attic, utility and storage
rooms.
Be sure no door or other obstruction blocks the smoke path to the smoke
alarm.
Installation Location
Install smoke alarms as close to the centre of the ceiling as possible, away
from light fittings and air-conditioning ducts. If this is not practical, put the alarm
on the ceiling, no closer than 50 cm from any wall or corner as shown in Fig. 3.
Fig. 3 – Smoke alarm location from walls
If some of your rooms have sloped, peaked, or gabled ceilings, try to mount
alarms 0.9 m measured horizontally from the highest point of the ceiling.
Where Not to Install Your Smoke Alarm
Nuisance alarms occur when smoke alarms are installed where they will not
work properly. To avoid nuisance alarms, do not install smoke alarms in the
following situations.
•In or near areas where combustion particles are present, such as
kitchens with few windows or poor ventilation, garages where there may
be vehicle exhaust, near furnaces, combustion heaters, and space
heaters. Combustion particles are the by-products of something that is
burning, which the smoke alarm may detect.
•Within 6 m of kitchens where combustion particles are normally present.
If a 6 m distance is not possible, e.g. in a mobile home, try to install the
smoke alarm as far away from the combustion particles as possible,
preferably on the wall. Ensure the area is well ventilated.
•In dead-air areas, where ventilation systems cause air-flow that would
not pass through the smoke alarm sensing chamber. Avoid also air-flow
from areas where normal combustion particles are expected, such as
kitchens. Fig. 4, which indicates the correct and incorrect smoke alarm
locations.
Fig. 4 – Dead-air areas
•In damp or very humid areas, or within 3 m of bathrooms with showers.
Moisture in humid air can enter the sensing chamber, then condense into
droplets upon cooling, which can cause nuisance alarms.
•In very cold or very hot areas, including unheated buildings or outdoor
rooms. If the temperature rises above or falls below the operating range
of smoke alarm, it may not function properly. The temperature range for
your smoke alarm is 0 °C ~ 45 °C.
•In very dusty or dirty areas. Dirt and dust can build up on the smoke
alarm’s sensing chamber, to make it overly sensitive. Additionally, dust
or dirt can block openings to the sensing chamber and limit the smoke
alarm from sensing smoke.
•Near fresh air vents or high draft areas like air conditioners, heaters or
fans, fresh air vents and drafts, which can drive smoke away from smoke
alarms.
•In dead air spaces, which are often at the top of a peaked roof or in apex
of ceilings and walls. Dead air may prevent smoke from reaching a
smoke alarm. See Fig. 3 and 4 for recommended mounting locations.
•In insect-infested areas. If insects enter a smoke alarm’s sensing
chamber, they may cause a nuisance alarm. Where insects are a
problem, get rid of them before installing the smoke alarm.
•Near fluorescent lights. Electrical “noise” from fluorescent lights may
cause nuisance alarms. Do not install smoke alarms within 1.5 m of such
lights.
In the above locations, a heat alarm could be installed as additional protection.
Also the product shall not be contaminated by paint.
Installation
Please read the previous section Installation Preparation, before
commencing installation.

Low Battery Alert
When the battery becomes depleted, the smoke alarm will signal a short beep
every 48 s. Immediately replace the battery with an approved model (see the
section User Replaceable Parts).
NOTE: Batteries supply a lower voltage in cold conditions, so the Low Battery
signal may start operating late at night. To avoid annoyance, keep a spare
battery on hand. The Low Battery signal will operate for at least 30 days.
Protection From Fire
Installing smoke alarms is only one step in protecting your family from fires.
You should also reduce the chances that fires will start in your home and you
must increase your chances of escaping safely if one does start. The following
information will help you develop a fire safety program.
1. Install smoke alarms properly. Carefully follow all the instructions in this
manual. Keep your smoke alarms clean, and test them every week.
2. Non-working smoke alarms will not alert you. Replace your smoke
alarms immediately if they are not working properly.
3. Follow fire safety rules, and prevent hazardous situations:
•Use smoking materials properly. Never smoke in bed.
•Keep matches and cigarette lighters away from children.
•Store flammable materials in proper containers. Never use them
near open flames or sparks.
•Keep electrical appliances in good condition. Do not overload
electrical circuits.
•Keep stoves, fireplaces, chimneys, and barbecue grills grease free.
Make sure they are properly installed and away from any
combustible materials.
•Keep portable heaters and open flames such as candles away
from combustible materials.
•Do not allow rubbish to accumulate.
•Keep a supply of extra batteries on hand for your battery powered
smoke alarms.
Prepare and practice a family escape plan. Review the following with your
children each time you have fire escape drills. This will help everyone
remember them in case of a real fire emergency.
1. Don’t panic and stay calm. Your safe escape may depend on thinking
clearly and remembering what you have practiced.
2. Get out of the house as quickly as possible. Follow a planned escape
route. Do not stop to collect anything or to get dressed.
3. Feel the doors to see if they are hot. If they are not, open them carefully.
Do not open a door if it is hot. Use an alternate escape route.
4. Stay close to the floor. Smoke and hot gases rise.
5. Cover your nose and mouth with a wet or damp cloth. Take short,
shallow breaths.
6. Keep doors and windows closed. Open them only if you have to in order
to escape.
7. Meet at your planned meeting place after leaving the house.
8. Call the Fire Service as soon as possible from outside your house. Give
the address and your name.
9. Never go back inside a burning building.
10. Contact your local Fire Service. They will give you more ideas about how
to make your home safer from fires and how to plan your family’s escape.
