Ei Electronics Ei 100TYC - Manual

1. Basic Information about your Smoke Alarm
A Smoke Alarm is an early warning device. Used correctly it can give you
and your family valuable extra time to escape.
Push the power-on button (inside the cover) until it clicks to connect the
battery permanently. Close the cover and press the test button - horn
should sound. Note: Battery cannot be disconnected using the power on
button.
· A Smoke Alarm does not prevent fires.
· Install correctly, in the centre of the ceiling if possible.
· Test weekly.
· Plan your escape route.
· Proper protection may require more than one Smoke Alarm.
· If you have any doubt or query about Smoke Alarms consult the sup-
plier or your local Fire Brigade.
· Nuisance alarms can be quickly silenced for 8 minutes by pressing the
hush button on the cover.
· The complete smoke alarm must be replaced by the year marked on
the unit.
· The complete Smoke Alarm must also be replaced if it beeps every 40
seconds for over an hour as this indicates the battery is depleted. Cut
the “end of life” red wire before discarding, to stop beeps.
2. Locating your Smoke Alarm
Sufficient smoke must enter your Smoke Alarm before it will respond.
Your Smoke Alarm needs to be within 10 paces (7.5 metres/25 feet) of the
fire to respond quickly. It also needs to be in a position where its alarm can
be heard throughout your home, so it can wake you and your family in time
for you all to escape. A single Smoke Alarm will give some protection if it
is properly installed, but most homes will require two or more to ensure
that a reliable early warning is given. For maximum protection you should
put individual Smoke Alarms in all the rooms where fire is most likely to
break out.
Your first Smoke Alarm should be located between the sleeping area and
the most likely sources of fire (living room or kitchen for example). But it
should not be more than 10 paces (7.5 metres) from the door to any room
where a fire might start and block your escape from the house.
(a) Single Storey Dwelling.
If your Home is on one level (a bungalow or mobile home for example) you
should put your first Smoke Alarm in a corridor or hallway between the
sleeping and living areas. Place it as near to the living area as possible,
but make sure you can hear it loudly enough to wake you in the bedroom.
(for example, see figure 1)
If your bungalow is very large and the corridor or hallway is more than say
20 paces (15 metres) long, one Smoke Alarm will not be sufficient. This is
because no matter where it is located it will be more than 7.5 metres from
potential fires.
In houses with more than one sleeping area, Smoke Alarms should be
placed between each sleeping area and the living area (for example, see
figure 2).
(b) Multi Storey Dwellings.
Multi storey dwellings should have a smoke alarm at each level (see fig-
ure 3). The best place for your first Smoke Alarm is in the downstairs hall-
way near the stairs. This is because smoke is likely to be detectable in the
hallway before it reaches the upstairs landing and bedrooms. Your sec-
ond Smoke Alarm should be upstairs, because the downstairs Smoke
Alarm is unlikely to detect the smoke from a fire in a bedroom upstairs.
(c) Maximum Protection.
For maximum protection you should put individual Smoke Alarms in all
the rooms where fire is most likely to break out (apart from the locations to
avoid, mentioned on page 4). The living room is the most likely place for a
fire to start at night, followed by the kitchen and then the dining room. You
should also consider putting Smoke Alarms in any bedrooms where fires
might occur, for instance, where there is an electrical appliance such as
an electric blanket or heater, or where the occupant is a smoker. You
should also consider putting Smoke Alarms in any rooms where the occu-
pant is unable to respond very well to a fire starting in the room, such as an
elderly or sick person or a very young child.
(d) Checking you can hear your Smoke Alarm.
With the Smoke Alarm sounding in its intended location, check you are
able to hear it in each bedroom with the door closed, above the sound of
your radio. The radio should be set to a reasonably loud conversation
level. If you can’t hear it over your radio the chances are that it wouldn’t
wake you.
If a Smoke Alarm is too far away for it to wake you, it is best to link it to an-
other Smoke Alarm near the bedroom. The model
Ei 100TYC Smoke
Alarms can be interconnected so when one alarm senses smoke, all con-
nected alarms respond. (see page 6 for further details).
3. Positioning your Smoke Alarm
(a) Ceiling Mounting.
Hot smoke rises and spreads out, so a central ceiling position is the pre-
ferred location. The air is “dead” and does not move in corners, therefore
Smoke Alarms must be mounted away from corners. Place the unit at
least 300mm (12 inches) from any light fitting or decorative object which
might obstruct smoke entering the Smoke Alarm. Keep at least 300 mm
(12 inches) away from walls and corners. See figure 4.
(b) Wall Mounting.
When a ceiling position is not practical (for example on a ceiling having
exposed beams or joists, or built-in radiant heating) put the top edge of
your Smoke Alarm between 150 and 300mm (6 and 12 inches) below the
ceiling. Keep at least 300mm (12 inches) from corners. (see figure 4).
(c) On a sloping Ceiling.
In areas with sloping or peaked ceilings install your Smoke Alarm 900mm
(3 ft) from the highest point measured horizontally (see figure 5), because
“dead air” at the apex may prevent smoke from reaching the unit.
(d) Locations to Avoid.
Don’t place your Smoke Alarm in any of the following areas:
· Bathrooms, kitchens, shower rooms, garages or other rooms
where the smoke alarm may be triggered by steam, condensation,
normal smoke or fumes. Keep at least 6 metre (20 ft) away from
sources of nuisance alarms - wall mounting if necessary.
· Attics or other places where extremes of temperature may occur (be-
low 4
° C/34 ° F or above 40 ° C/104 ° F).
· Near a decorative object, door, light fitting, window molding etc.,
that may prevent smoke from entering the Smoke Alarm.
· Surfaces that are normally warmer or colder than the rest of the room
(for example attic hatches, uninsulated exterior walls etc). Tempera-
ture differences might stop smoke from reaching the unit.
· Next to or directly above heaters or air conditioning vents, win-
dows, wall vents etc. that can change the direction of airflow.
· In very high or awkward areas where it may be difficult to reach the
alarm (for testing, etc).
· Locate unit at least 1.5m (5 feet) and route wiring at least 1m (3 feet)
away from fluorescent light fittings as electrical “noise” and/or flick-
ering may affect the unit.
· Locate the unit at least 1 metre (3ft) from dimmer controlled lights
and wiring - some dimmers can cause interference.
· Locate away from very dusty or dirty areas as dust build-up in the
chamber can make unit too sensitive and prone to alarm. It can also
block the insect screen mesh and prevent smoke from entering the
chamber.
· Do not locate in insect infested areas. Small insects getting in to the
chamber can cause intermittent alarms.
(e) Nuisance/False Alarms.
If, when the alarm goes off, there is no sign of smoke heat or noise to indi-
cate that there is a fire, you should get your family into a safe place, before
you start investigating.
Check the house carefully in case there is a small fire smouldering some-
where.
Check whether there is some source of smoke or fumes, for example
cooking fumes being drawn past the Smoke Alarm by an extractor.
If there are frequent nuisance/false alarms it may be necessary to re- lo-
cate the device away from the source of the fumes.
This Smoke Alarm is designed for more difficult areas, as you can silence
the alarm for 8 minutes. This gives time for smoke or fumes to clear, (see
page 7 for more details).
4. Installing your Smoke Alarm
(a) Attaching to Ceiling or Wall.
(NB details of how to interconnect the Smoke Alarm Ei 100TYC are given
on page 6).
The Smoke Alarm is battery operated and needs no wiring, (except when
interconnecting). Use figure 6 below, as a help in mounting.
1. Pull Cover open at Tab (2). Remove Cover from Base by separating at
rear Snap-in Hinges (5).
2. Place the Base on ceiling or wall exactly where you want to mount the
unit. With a pencil, mark the location of the Screw Holes (6)
3. Taking care to avoid any electrical wiring in the ceiling or wall, drill a
hole through the centers of the marked locations. Push the plastic Screw
Anchors provided into the drilled holes. Screw in firmly.
(b) Connecting the built-in Lithium battery.
Push the power-on button (8), (see figure 6) until it clicks to connect the
battery permanently. Note: You may hear a loud chirp when pressing the
button. This is normal.
To close the cover match up the snap-in hinges (5) and gently press to-
gether until they are attached. Press the test button (3) - the horn should
sound to show the Smoke Alarm is now working. If the horn does not
sound try pushing the power-on button (8) again. Note: The power-on but-
ton cannot be used to disconnect the battery.
5. Interconnecting your Smoke Alarm
A maximum of twelve Ei 100TYC Smoke Alarms may be wired together
such that when one unit senses smoke all other units sound a warning.
This helps ensure smoke alarms will be heard. (Model
Ei 100TY & Ei
100TYK can not be interconnected).
The Ei 100TYC Ionisation Smoke Alarm may also be interconnected to
the Ei Optical Smoke Alarm, model number Ei 3105TYC.
Warning: Do not interconnect to any other Smoke Alarms
A maximum of 250 metres (820 feet) of wire can be used, (maximum re-
sistance between detectors 50 ohm). The units are interconnected by wir-
ing all the terminals marked 1 together, and all the terminals marked 2
together, as shown in Figure 7. An opening should be made in the label
covering the wiring hole in the base, and the wires routed into the unit as
shown. Note that the wiring inside the unit must be kept clear of the test
button contacts, but must not impede the air flow. Draughts from wiring
openings, conduit, or mounting boxes/holes, may blow smoke away from
the sensing chamber, making it insensitive. It is essential that all such
openings are sealed by silicone sealant or similar.
After wiring together the Interconnect Smoke Alarms, test the first unit by
pressing the button. All the detectors should alarm within about 5 sec-
onds. Check all the other units similarly.
These Smoke Alarms should be interconnected only within the confines
of a single family living unit. If they are connected between different units
there may be excessive nuisance alarms. Everybody may not be aware
that they are being tested or that it is a nuisance alarm caused by cooking
etc.
Indicator light
When interconnected units are in alarm the fast flashing red light behind
the test button indicates the unit initiating the alarm. To silence a nuisance
alarm, the hush button on the unit with the fast flashing red light must be
pushed. (Pressing the hush button on any of the other units will not silence
the alarm.)
6. Looking after your Smoke Alarm
(a) Testing your Smoke Alarm
It is recommended that you test your Smoke Alarm once a week to be sure
the unit is working. It will also help you and your family to become familiar
with the sound of the Alarm.
Press and hold the test but-
ton until the Alarm sounds (it
may take up to 10 seconds),
(Figure 8). The Alarm will
stop sounding shortly after
the button is released. If the
Alarm fails to sound, follow
this checklist.
1. Press the power on button
to connect the battery per-
manently.
2. Check the cover is cor-
rectly snapped on to its
hinge and that it is fully
closed.
3. Refer to “Cleaning Your Smoke Alarm” 6 (c) below.
WARNING: Do not test with flame.
This can set fire to your Smoke Alarm and damage your house.
We do not recommend testing with smoke as the results can be mislead-
ing unless special apparatus is used. Pressing the test button simulates
the effect of smoke during a real fire and is the best way to ensure the
Smoke Alarm is operating correctly.
Power Indicator Light.
Some Smoke Alarms (models Ei100TY and Ei100TYC) have a Power In-
dicator Light which flashes once a minute through the test button to show
the Smoke Alarm is powered. Check regularly. Replace the Smoke Alarm
if the flashing stops. (This does not apply to the Ei100TYK model)
(b) Hush Button
This model has a special false Alarm silencer feature to help you control
nuisance false alarms.
1. To cancel a false Alarm, press the Hush Button located on the lower
right-hand corner. The Alarm will automatically switch to a reduced sensi-
tivity condition. This condition allows unwanted alarms to be silenced for a
period of approximately 8 minutes.
2. The unit will reset to normal sensitivity at the end of the silenced period.
If additional silenced time is required, simply push the Hush Button again.
3. To quickly return to normal non-silenced operation, simply push the
Test Button; the Alarm will sound briefly and return to its normal, sensitive
Alarm mode.
