Normal Operation Indicators Explained
Power Up
Twist off the Detector from the mounting plate (see Quick
Start Guide). Remove the battery tab to power the Detector,
the red LED will flash once followed by one flash of the
yellow LED to indicate that the Detector has been powered
successfully and is now in standby mode.

4
Standby
In standby mode there are no active visible or audible
indications to the occupant. To confirm that the Detector is
operational perform a weekly button test.
Weekly Button Test
Press and hold the test button and verify that the red LED
flashes rapidly and the Detector ramps up to full sound.
Sensing Fire
As soon as the Detector senses smoke it will go into alarm
(along with any interconnected Detectors). The red LED on
the Detector sensing smoke flashes rapidly to indicate this is
the Detector sensing smoke / fire. Follow the instructions in
section 3 and evacuate the building.
Silence False / Nuisance Detector Activations
Occasionally Smoke Detectors can be activated by phenomena
other than fire, such as dust, insects, cooking smoke and
shower steam. Once you are sure it is a nuisance activation
press the large test button to silence the Detector for 10
minutes – the red LED will then flash every 8 seconds for
10 minutes. Pressing the test button will make the unit less
sensitive, but if a large amount of smoke / steam / dust is
observed the unit will remain in the activation condition.
Nuisance activation in an Interconnected System
In the case of a real fire, the occupiers of the dwelling
should proceed to evacuate as per instructions in section 3.
However, if the system is responding to a recurring nuisance
activation it is very important that the Detector at fault is
identified so the problem can be eliminated by cleaning or
replacing the Detector. The Detector at fault can be identified
by a rapidly flashing red LED. Once it has been located follow
directions for Silence False / Nuisance Detector Activations
above.
Fault Condition Indicators Explained
Low Battery
The Detector will emit a short beep and flash the Yellow LED
when it becomes partially depleted. Check the date when the
Detector should be replaced which is given on the sidewall of
the Detector. When electronic self testing indicates that the
battery is becoming low the Detector will beep, and the yellow
LED will flash at the same time (about every 48 seconds) to
warn the user. This indicates that the battery or batteries must
be replaced.
Contaminated Chamber
If the Detector sounds with no apparent smoke present, press
the test button to silence it for 10 minutes (as described
above). If Detector sounds again it may be contaminated.
Pressing the test button again, within 4 minutes of the
Detector re-sounding, will cause the Detector to compensate
for chamber contamination and normally resolve the problem.
If the Detector re-sounds a third time, it is likely that the
Detector is excessively contaminated and needs replacing.
If it is not convenient to replace it immediately, pressing the
test button within 4 minutes of it going into alarm (for the
third time) will silence the Detector for 8 hours – however
it will give two short beeps (second apart) every 10 minutes
to remind the user it has been disabled. If the contamination
clears the Detector will return to normal operation.
(Note: this does not reduce the users fire protection, as a
Smoke Detector in continuous alarm due to a fault, is useless
and must be silenced – by taking the Detector down or as
described here. This procedure has the added benefits that
the user is reminded every 10 minutes by two short beeps
that the Detector needs to be replaced and that if the
problem clears the Detector will return to detecting fire).
The unit should flash the yellow LED 4 times if dust level is
too high and user should clean the Detector as described in
section 8.4.

Faulty Smoke Chamber
In the unlikely event of the smoke sensing chamber becoming
defective, the Detector will give 2 short beeps with 2 yellow
LED flashes every 48 seconds. The Detector must then be
replaced. If it is not convenient to replace it immediately,
pressing the test button will silence the beeps and stop the
yellow LED flashing for 12 hours. This can be repeated as
required.
End of Life
When the sensor has reached its End of Life the Detector will
beep and flash the amber light 3 times every minute. The
remedy for this failure is to replace the Detector.
The number of Detectors necessary for minimum protection is
mandated by the NFPA (National Fire Protection Association)
as shown below:
NATIONAL FIRE PROTECTION ASSOCIATION REQUIRED
PROTECTION
Where required by applicable laws, codes, or standards for the
specified occupancy, approved single- and multiple-station
Smoke Detectors shall be installed as follows:
(1) In all sleeping rooms and guest rooms
(2) Outside of each separate dwelling unit sleeping area
within 6.4m (21ft) 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 (small facility)
* Where two or more Detectors are installed they shall be
interconnected.
The equipment should be installed using wiring methods in
accordance with the National Fire Protection Association’s
Standard 72, Chapter 11. (National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269).
ELK-6052 Smoke Detectors and ELK-6053 Heat Detectors
are designed for use with ELK-M1 Alarm Control panels and
ELK-M1XRFTWM Wireless Receivers and utilize Wireless
Two-Way communications which provides for the required
interconnection of two or more Detectors.
The required number of smoke Detectors may not provide
reliable early warning protection for those areas separated
by a door from the areas protected by the required smoke
Detectors. For this reason, it is recommended that the
occupant consider the use of additional smoke Detectors for
those areas for increased protection. The additional areas
include the basement, bedrooms, dining room, furnace room,
utility room, and hallways not protected by code mandated
smoke Detectors. The installation of smoke detectors in
bathrooms, shower rooms, kitchens, attics (finished or
unfinished), or garages is not normally recommended, as
these locations occasionally experience conditions that can
result in improper operation. Heat Detectors can be installed
in kitchens, garages and other areas where Smoke Detectors
are unsuitable.
IMPORTANT!
Specific requirements for Smoke Detector installation vary
from state to state and from region to region. Check with your
local Fire Department for current requirements in your area.

2. Location, Positioning & NFPA Requirements

SMOKE DETECTION
Sufficient smoke must enter your Smoke Detector before it will
respond. Your Smoke Detector needs to be within 6m (20ft) of
the fire to respond quickly. Smoke Detectors also need to be in
positions where they can be heard throughout the property,
so they can wake you and your family in time for everyone to
escape. A single Smoke Detector will give some protection if it
is properly installed, but most homes will require at least two
or more Detectors, interconnected to ensure that a reliable
early warning is given. For recommended protection you
should put individual Smoke Detectors in all rooms where fire is
most likely to break out (apart from the kitchen and bathroom).
Multi Level Dwellings
If your home has more than one floor, at least one Detector
should be fitted on each level (see Figure 1) and still following
the minumum NFPA requirements. When two or more
Detectors are installed they shall be interconnected so as to
provide sufficient warning throughout the property.
Figure 1 illustrates where Smoke and Heat Detectors should
be located in a typical two story house. Note the spacings in
“Protection Levels” which ensure the early detection of fire
and that the warning will be heard.
Heat Detectors should be located in places were Smoke
Detectors are unsuitable - i.e. kitchen, garage, furnace room,
Single Story Dwelling
6
Figure 1
For minimum protection and as per NFPA requirements
Smoke Detectors shall be installed as follows:
- In all sleeping rooms and guest rooms
- Outside of each separate dwelling unit sleeping area within
6.4m (21ft) of any door to a sleeping room, the distance
measured along a path of travel
- On every level of a dwelling unit, including basements
- On every level of a residential board and care occupancy
(small facility), including basements and excluding crawl
spaces and unfinished attics.
- In the living area(s) of a guest suite
- In the living area(s) of a residential board and care occupancy
(small facility)
- all units interconnected
For recommended protection (in addition to the above) Smoke
Detectors may be installed in:
- All rooms (except unsuitable locations such as kitchen, baths,
garage, etc.)
- In locations unsuitable for Smoke Detectors consider
installing Heat Detectors placed within 5.3m (17ft) of
potential fire sources.

If the premises is one story you should put your first Smoke
Detector in a corridor or hallway between the sleeping and
living areas. Place it as near to the living area as possible, but
make sure that it can be heard loudly enough in the bedroom
to wake someone. See Figure 2 for placement example.
In houses with more than one sleeping area, Smoke Detectors
should be placed between each sleeping area and the living
area and it is recommended that Heat Detectors should be
placed in the kitchen and garage.
Recommended Protection
Checking to Make Sure Detectors Can Be Heard
With the Detectors sounding in their intended locations check
to make sure that the sound can be heard in each bedroom
with the door closed, above the sound of any TV/audio
systems. The TV/ audio systems should be set to a reasonably
loud conversation level. If you cannot hear the Detector
sounding its alarm over the sound of a TV/audio system,
the chances are it would not wake you. Interconnecting the
Detectors will help to ensure that the Detector sound will be
heard throughout the property.
Positioning
Ceiling Mounting
Hot smoke rises and spreads out, so a central ceiling position
is the recommended location. The air is “dead” and does
not move in corners, therefore Smoke Detectors must be
mounted away from corners. Keep at least 305mm (12”) from
walls and corners (see Figure 3). Additionally, mount the unit
at least 305mm (12”) from any light fixture or decorative
object that might prevent smoke from entering into the
Smoke Detector.
Wall Mounting
If ceiling mounting is impractical, Smoke Detectors may be
mounted on a wall, provided that:
a) the top of the smoke Detector is between 150mm (6”) and
305mm (12”) below the ceiling;
b) the bottom of the smoke Detector is above the level of any
door openings;
Wall mounting should only be considered where closely
spaced beams or similar obstructions may preclude ceiling
mounting. It is considered to be the responsibility of the
installer/client to determine if the presence of asbestos in the
ceiling material would make ceiling mounting ‘impractical’.

On a Sloping Ceiling
With a sloping or peaked ceiling install a Smoke Detector
within 610mm (24”) of the peak (measured vertically). If this
height is less than 610mm (24”) the ceiling is regarded as
being flat (see Figure 4).
Locations to avoid
DON’T place Smoke Detectors in any of the following areas:
• Bathrooms, kitchens, showers, garages or other rooms
where the Smoke Detector may be triggered by steam,
condensation, cooking smoke, etc. Keep at least 6m (20ft)
away from potential sources of cooking smoke, fireplaces, etc.
• Locate away from very dusty or dirty areas as dust build-up
in the chamber can impair performance. It can also block the
insect screen mesh and prevent smoke from entering the
smoke Detector chamber.
• Do not locate in insect infested areas. Small insects getting
into the Smoke Detector chamber can cause intermittent
Detector alarming conditions.
• Places where the normal temperature can exceed 100°F
(38.7°C) or be below 40°F (4.4°C) such as attics, furnace
rooms, directly above ovens or cooktops, bathrooms,
etc., as mounting in such locations could cause nuisance
Detector alarming conditions.
• Near a decorative object, door, light fixtures, window
molding etc., that may prevent smoke from entering the
Detector.
• Surfaces that are normally warmer or colder than the rest of
the room (e.g. attic access). Temperature differences might
stop smoke from reaching the Detector.
• Next to or directly above heaters or air conditioning vents,
windows, wall vents etc. that can change the direction of
airflow.
• In very high or confined areas (e.g. over stairwells) where it
may be difficult to reach the Detector (for testing, hushing
or battery replacement).
• Locate the Detector at least 900mm (3ft) from dimmer
controlled lights and wiring as some dimmers can cause
interference.
• Locate Detector at least 1.5m (5ft) and route wiring at
least 1m away from fluorescent light fixtures as electrical
“noise” and/or flickering may affect the unit.
When using household protective devices, basic safety
precautions should always be followed, including those listed
below
• Please read all instructions.
• Rehearse emergency escape plans so everyone at home
knows what to do in case the Detector sounds.

• Use the Test Button to familiarize your family with the
Detector sound and to practice fire drills regularly with all
family members. Draw up a floor plan that will show each
member at least two escape routes from each room in the
house. Children tend to hide when they don’t know what
to do. Teach children how to escape, open windows, and
use roll up fire ladders and stools without adult help. Make
sure they know what to do if the Detector sound goes off.
• Constant exposures to high or low temperatures or high
humidity may reduce battery life.
• Nuisance Detector sounds can be quickly silenced by
fanning vigorously with a newspaper, by removing the
Detector from its base or pressing the test / hush button.
• Do not attempt to recharge, or burn the battery, as it may
explode.
• In the event that the batteries may have leaked or
corroded, handle carefully to avoid possible eye damage
or skin irritation.
• To maintain sensitivity to smoke, do not paint or cover the
Detector in any manner; do not permit accumulation of
cobwebs, dust, or grease.
• If Detector has been damaged in any way or does not
function properly, do not attempt a repair - see section 5
‘Getting Your Detector Serviced’.
• Smoke Detectors must be mounted following the
instructions provided in this manual.
• Smoke Detectors are not a substitute for insurance. The
supplier or manufacturer is not your insurer.
Fire Safety Hints
Store fuel and other flammable materials in proper containers.
Discard oily or flammable rags.
Always use a metal fireplace screen and have chimneys
cleaned regularly.
Replace worn or damaged sockets, switches, home wiring and
cracked or frayed electrical cords and plugs.
Do not overload electrical circuits.
Keep matches away from children.
Never smoke in bed. In rooms where you do smoke, always
check under cushions for smoldering cigarettes and ashes.
Be sure all electrical appliances and tools have a recognized
approval label. Smoke Detectors are not to be used with
detector guards unless the combination has been evaluated
and found suitable for that purpose.
This device cannot protect all persons at all times. It may not
protect against the three most common causes of fatal fires:
• Smoking in bed.
• Leaving children at home alone.
• Improper use of flammable liquids.
Further information can be obtained from the Fire
Department.
What to Do In The Event Of A Fire
1. Check room doors for heat or
smoke. Do not open a hot door. Use
an alternate escape route. Close
doors behind you as you leave.
2. If smoke is heavy, crawl out,
staying close to floor. Take short
breaths, if possible, through a wet
cloth or hold your breath. More
people die from smoke inhalation
than from flames.

3. Get out as fast as you can. Have a
prearranged meeting place outside
for all family members. Check to
make sure everyone is accounted for.
4. Call the Fire Department from a
neighbor’s house or mobile phone.
Remember to give your name and
address.
5. NEVER re-enter a burning house.
Limitations of Smoke Detectors
While Smoke Detectors are extremely effective, independent
authorities have stated that under some circumstances they
may become ineffective. A number of reasons for this are:
• Smoke Detectors will not work if the batteries are depleted
or if they are not correctly installed. Replace the batteries
if necessary. Also check the replace by date on the side of
the Detector.
• Smoke Detectors will only work when sufficient smoke
reaches the Detector. Smoke may be prevented from
reaching the Detector if the fire is too far away, for
example, if the fire is on another floor, behind a closed
door, in a chimney, in a wall cavity, or if the prevailing
air drafts carry the smoke or heat away. Installing Smoke
Detectors on both sides of closed doors and installing
more than one Detector as recommended by code, may
significantly improve the probability of early detection.
• The Smoke Detectors may not be heard due to other loud
noise, hearing impairment, etc.
• A Smoke Detector may not wake a person who has taken
drugs or alcohol.
• Certain types of fires may be difficult to detect in time to
provide sufficient early warning. Examples include; fires
caused by smoking in bed, gas leaks, explosions, poor
storage of flammable rags and/or liquids, for example fuels,
paint, paint thinner, etc., overloaded electrical circuits, or
children playing with matches.
• Current studies have shown that Smoke Detectors may not
awaken all sleeping individuals. It is the responsibility
of individuals in the household who are capable of
assisting others, to provide assistance to those who
may not be awakened by the Detector alarming sound,
or to those who may be incapable of safely escaping the
area unassisted.
Limitations of Heat Detectors
There are various situations where a Heat Detector may not
be effective:
• Fires where the victim is directly exposed to flame for
example; clothes catching fire while cooking.
• Fires where the heat is prevented from reaching the Heat
Detector due to a closed door or other obstruction.
• Incendiary fires where the fire grows so rapidly that an
occupant’s egress is blocked even with properly located
Heat Detectors
If your Detector fails to work after you have read the sections
on “Installation”, “Testing and Maintenance”, then contact
Customer Service at the address given at the end of this manual.

similarly.
Installer shall conduct a go/no-go field test using approved
canned smoke product: “SMOKE CHECK, Model 25S, Smoke
Detector Tester.” Follow Instructions printed on the can.
Contact your Central Monitoring Station to notify them of
the impending test.
Tamper Proofing the Detectors
The Detector can be made tamper proof to prevent
unauthorized removal of the Detector.
Break off the small pillar on the base as shown in Figure 8a.
To remove the Detector from the ceiling it is now necessary
to use a small screwdriver, to release the catch (push catch
towards the ceiling) and then twist off the Detector (see
Figure 8b).

If necessary, it is possible to further secure the Detector by
using a 2-3mm (1/8”) diameter x 6-8mm (1/4”) long self
tapping screw (not supplied) to firmly lock the Detector and
its’ mounting plate together (see Figures 8c and 8d).
Attach the Detector to the mounting plate.
Line up the screw (not supplied) on the “U” shaped recessed
area shown in Figure 8c and install screw until fully secured.
To remove the Detector from the ceiling, remove the screw
first, and then twist off counterclockwise.
Your Detector is a life safety device and should be checked
periodically.
Manually Testing your Detectors
It is recommended that you test your Detectors after
installation and then at least weekly to ensure the units are
working. It will also help you and your family to become
familiar with the Detector alarming sound.
- Press and hold the Test Button until the Detector sounds
and the red LED flashes (see Figure 7). The Detector will
stop sounding shortly after the button is released.
- Repeat this procedure for all other Detectors in the system.
WARNING: Do not test with flame. This could set fire to
the Detector and damage the house. We do not recommend
testing with actual smoke as the results can be misleading
unless special apparatus is used.
When you press the Test button it simulates the effect of
smoke in a Smoke Detector which it could experience in a
real fire.
Test/Silence Button to Control Nuisance Detectors
The Smoke Detector has a combined Test/Silence button to
help you control nuisance/false detections.
When the Detector sounds if there is no sign of smoke or
noise to indicate that there is a fire, it should be assumed that
it is due to an actual fire, the dwelling should be evacuated
immediately and contact the local Fire Department.
It is possible that cooking smoke, steam, etc., may be the
source of a nuisance/false detection.
If there are frequent nuisance/false detection of alarms, it
may be necessary to re-locate the Detector away from the
source (cooking smoke, shower steam, etc.)

1. To cancel a false detection from a Detector (which has its
red light flashing rapidly), press the Test/Silence button and
the Smoke Detector will automatically switch to a reduced
sensitivity condition.
The Smoke Detector will be silenced for a period of
approximately 10 minutes. The red light on the cover of the
Smoke Detector will flash every 8 seconds to indicate that the
unit has been silenced.
2. The Smoke Detector will reset to normal sensitivity at the
end of the 10 minute silenced period. If additional silenced
time is required, simply push the Test/Silence button again.
3. If kitchen usage/layout is such that there is an unacceptable
level of nuisance detection of alarms, re-locate the Smoke
Detector further away where it will be less affected by cooking
smoke, steam, etc.
We recommend the use of a Heat Detector in the Kitchen
area to avoid such nuisance detection of alarms.
What to do when a Detector is beeping:
Detector will beep twice every 48 seconds and yellow LED will
flash if the smoke chamber is degraded. See Smoke Detector
Auto Self-Test for details.
Detector will beep once every 48 seconds and yellow LED
will flash for at least 30 days when the battery power is low.
This indicates that it is time to replace the Battery(s). Battery
replacement should also be done if the Detector does not
sound when the Test Button is pressed.
Battery Replacement
Use only specified battery model: Panasonic CR123A
Use of a different battery may have a detrimental effect on
Detector operation.
After replacing the battery always press the Test button to
check that the Detector is functioning correctly.
WARNING!
CONSTANT EXPOSURES TO HIGH OR LOW TEMPERATURES OR
HIGH HUMIDITY MAY REDUCE BATTERY LIFE.
These batteries are intended for use at ordinary temperatures
where anticipated high temperature excursions are not
expected to exceed 212°F (100°C).
Prolonged periods of Detector sounding will also reduce
battery life.
CAUTION: The battery used in this device may present a fire
or chemical burn hazard if mishandled. Do not recharge,
disassemble, heat above 212°F (100°C )or dispose of in fire.
Replace battery with Panasonic CR123A, use of another
battery may present a risk of fire or explosion.
Dispose of used battery promptly. Keep away from children.
Do not disassemble and do not dispose of in fire.
Cleaning your Detector
Clean your Detector regularly. Use a soft bristle brush or the
brush attachment of your vacuum cleaner to remove dust and
cobwebs from the side slots where the smoke enters. To clean
the cover, wipe with a damp cloth and dry thoroughly.

Chamber Cleaning
Cleaning or replacing of the chamber cover should only be
carried out by suitably trained personal.
1. Remove the Detector from the mounting plate.
2. Remove the battery or batteries.
3. With a flat screwdriver unclip the three cover clip points (see
figure 9a).
4. Remove the cover (see figure 9b).
5. If the unit is a model containing a thermistor you will need
to unplug the thermistor by holding the thermistor PCB and
pulling the pins out of the sockets (see figure 9c).
6. To remove the chamber top turn the chamber anti-clockwise
approx. 15 degrees (see figure 9d).
7. Blow out or use a soft bristled brush to remove dust and dirt
from the chamber base.
8. Fit a new chamber top and clip in place by turning clock-wise
15 degrees.
9. Insert the thermistor PCB into the sockets and ensure the
thermistor is perpendicular to the chamber (see figure 9e).
10. Place the cover back on the Detector taking care to ensure
the thermistor is protruding through the cover (see figure 9f).
11. Replace the battery / batteries and reattach to the mounting
plate.

12. Press the test button to ensure the Detector is working correctly.
Smoke Detector Automatic Self-Test
The smoke chamber in the Smoke Detector automatically
tests itself every 16 seconds. If the chamber is degraded it
will beep twice every 48 seconds with 2 yellow LED flashes at
the same time. If this happens clean the unit. If the beeping
persists and the beep does not coincide with a yellow light
flash, return the unit for service (see Section 5 - Getting Your
Detector Serviced).
Dust and Insect Contamination
All Smoke Detectors and particularly the optical (photoelectric)
type are prone to dust and insect ingress which can cause a
nuisance/false detections.
The latest design, materials and manufacturing techniques
have been used in the construction of Detectors to minimize
the effects of contamination. However, it is impossible
to completely eliminate the effect of dust and insect
contamination, and therefore, to prolong the life of the
Detector you must ensure that it is kept clean so that excess
dust does not build up. Any insects or cobwebs in the vicinity
of the Smoke Detector should be promptly removed.
Excessive dust may cause the unit to fault with 4 amber
flashes every 48 seconds and 4 chirps with 4 flashes on test
button.
In certain circumstances even with regular cleaning,
contamination can build up in the smoke sensing chamber
causing the Detector to sound. If this happens the Smoke
Detector must be returned for servicing or replacement.
Contamination is beyond our control, it is totally unpredictable
and is considered normal wear and tear. For this reason,
contamination is not covered by the guarantee and a charge
is made for all such servicing work.
End of life
The entire Detector must be replaced if:-
• The unit is installed for over 10 years (check the “replace
by” date marked on the side of the unit).
Before the Detector is safely discarded, remove from the
mounting plate and disconnect the batteries.
Do not put the Detector into a fire.
The Detector should be disposed in a safe and environmentally
sound manner at your local recycling center.
Detector sounds for no apparent reason
• Enrolling your Detectors - see relevant RF Module
instructions. If the Detectors are in the default factory
settings neighboring units may cause them to sound.
• Check for smoke, steam, etc. from the kitchen or bathroom.
Paint and other fumes can cause nuisance alarms.
• Check for any sign of contamination such as cobwebs or
dust. Clean Detector as described in Section 8 if necessary.
• Press the Test/Silence button on the Smoke Detector
causing the alarm (this can be identified as the Detector
with the red light flashing rapidly) – this will silence the
Smoke Detector for 10 minutes.
The Detector fails to sound when the Test button is pressed
• Check the age of the unit - see the “replace by” label on
side of unit.
• If necessary, replace the battery or batteries with Panasonic
CR123A.
