STOVE GUARD SGK500 USER MANUAL
1.2 Structure of the Stove Guard
The Stove Guard is composed of an Intelligent Heat Sensor, attached underneath the cook-
er hood, on the wall or on the cooker panel, and a Control Unit, connected to the cooker.
With the additional Innohome Smart Socket, various distance alarms, like flashing lights or
vibrating alarms, can be linked to the system, or the Stove Guard can be set to automatically
operate the extractor fan. The Intelligent Heat Sensor, the Control Unit and the Smart Socket
communicate using a radio connection.
The Stove Guard can also be used with gas and dual-fuel cookers, with the additional gas in-
stallation kit, including an electric valve tted into the cooker gas supply.
The Control Unit has an alarm output that enables the Stove Guard to be linked to social alarm
systems, such as Telecare.
The Intelligent Heat Sensor outlook can be changed using optional colour covers.
The whole Intelligent Heat Sensor cover works as a
push-button, but it is recommendable to press it at the
point of the round light (1). Pressing the cover resets the
alarm, reconnects the gas/electricity supply to the cook-
er and turns o the Safety Lock. Green light (2) lights up
at one-minute intervals and when the Sensor is being
pressed. During an alarm, a red light ashes. Solar panels
(3) power the Sensor.
Distinguishing the Stove Guard type:
Stove Guard SGK500-2 includes a Control Unit SGC500-2 with one blue connector, SGK500-3
includes a Control Unit SGC500-3 with two white connectors.

1.3 Stove Guard use and features
Stove Guard use
When the cooker has been turned o and the Stove Guard is signalling, rst turn all cook-
er knobs to ‘0’, then press the Intelligent Heat Sensor cover once. In cookers that are operated
by touch, just press the Intelligent Heat Sensor cover once.
An Intelligent Heat Sensor pre-alarm signal, that has a short sound and a long break
(--___--___ ), sounds one minute before turning the cooker o. If the situation is not hazard-
ous, press the Intelligent Heat Sensor cover once during the pre-alarm signal. The Intelligent
Heat Sensor will learn that the situation was not hazardous.
A Control Unit pre-alarm signal (sounds from behind the cooker), that has a short sound
and a long break (--___--___ ), indicates that the Intelligent Timer will turn the cooker o after
one minute’s time. By pressing the Intelligent Heat Sensor cover once, you will get more time
to use the cooker.
If the Safety Lock has ‘locked’ the cooker, you can get it back in use by pressing the Intelli-
gent Heat Sensor cover once.
Stove Guard features
a) Overheating Monitor
The Intelligent Heat Sensor, installed above the cooker, reacts to a dangerously high temper-
ature or steep temperature rise. Several sensors with self-adjusting programming detect tem-
perature and its change. The Sensor ‘learns’ the users’ cooking styles, making hazard recogni-
tion precise, with no false alarms. The rate of temperature increase alarm is based on the steep
temperature rise that happens when the cooking vessel’s liquid has dried out. Reacting to the
temperature rise allows for an early detection and prevention of re risk situations.
The Intelligent Heat Sensor will rst sound a one minute-long pre-alarm signal (see Intelligent
Heat Sensor pre-alarm signal, on previous page), after which the cooker is turned o. Reset-
ting the pre-alarm signal causes the Intelligent Heat Sensor to become less sensitive.
The Intelligent Heat Sensor alarm is also reset automatically in about two minutes, after the
cooker has been turned o and the temperature starts to drop.
After automatic alarm reset, the cooker is turned back on normally: rst turn all cooker knobs
to ‘0’, then press the Intelligent Heat Sensor cover once. In cookers that are operated by touch,
the electricity supply is returned automatically (burners are o after the electricity cut-o).

STOVE GUARD SGK500 USER MANUAL
1. Innohome Stove Guard and how to use it (cont.)
N.B. The Overheating Monitor alarm is not triggered if the hob’s temperature is too low for
a hazardous situation to be identied, or if the cooker automatically limits a temperature in-
crease. When the alarm has been reset manually it cannot be triggered by the rate of temper-
ature change for 30 minutes, but can still be triggered by the heat level. The Stove Guard is an
additional safety device that does not necessarily cover all possible hazardous situations, but
does signicantly improve cooker safety.
b) Intelligent Timer
Electric cookers: The Intelligent Timer identies a burner that has been accidentally left on by
monitoring burner heat adjustments. If a burner has been left on, the cooker is turned off
within a time period between 30 minutes and 3 hours, depending on the burner setting - the
higher the setting the sooner the cooker is turned o (in some cookers, the oven is not turned
off). Before the cooker is turned off, the Control Unit will emit a one-minute long pre-alarm
signal (see Control Unit pre-alarm signal, on previous page). Resetting the pre-alarm signal will
restart the Timer.
Note that in some cookers that are operated by touch or have a clock, and with the SGK500-3
model in all electric cookers, the Intelligent Timer does not necessarily start if the burner is on
a very low heat setting.
Gas and dual-fuel cookers’ timer: The timer has a xed time and starts when the hob tempera-
ture starts to rise. The cooker is turned o after two hours (in some dual-fuel cookers the oven
is not turned o). Before the cooker is turned o, The Control Unit will emit a one-minute long
pre-alarm signal (see Control Unit pre-alarm signal on previous page). Resetting the pre-alarm
signal will give two hours more time.
c) Alarm Signal Detection (re, carbon monoxide and gas alarms)
The Stove Guard identies external (re, carbon monoxide and gas) alarm signals using sound
detection. An alarm signal emitted by an external alarm triggers the Stove Guard to turn the
cooker o (in some cookers the oven is not turned o).
d) Cooker knob Safety Lock
The Safety Lock can only be used with the SGK500-2 model and only on electric cookers with
mechanical knobs (excluding cookers with a clock). The Safety Lock ‘locks’ the cooker so that it
cannot be turned on accidentally, for example, by a child, a person with memory disorders, or
a pet. To use the cooker, press the Intelligent Heat Sensor cover once or turn one of the cooker
knobs on and o three times, at one second intervals (on, o – wait one second – on, o – wait
one second – on, o). The Control Unit emits two signals as the cooker is ready for use. The
cooker is ‘locked’ 20 minutes after last use. The Safety Lock feature can be activated or deacti-
vated by carrying out the Control Unit setup (see section 5).

STOVE GUARD SGK500 USER MANUAL
1.5 Sensor Dislocation Alarm
The Sensor Dislocation Alarm ensures that the Intelligent Heat Sensor is not accidentally re-
moved from its location. If the Sensor is removed, it will sound an alarm and the Control Unit
will turn the cooker off. To restore normal operation of the cooker, return the Sensor back to its
place and press the cover once.
If the Sensor cannot be returned back to its place, the alarm can be reset by switching the Con-
trol Unit power o for a moment, using the main switch. After this the cooker can be used for
30-45 minutes, when the Stove Guard will sound another alarm and turn the cooker o.
1.6 Automatic fault diagnosis
Electric cookers: The automatic fault diagnosis ensures that the Stove Guard is working per-
fectly each time the cooker is used for cooking (the diagnosis will not start if the cooker is only
used for a short period of time eg. to boil water). The diagnostic tool analyses the function of
the Intelligent Heat Sensor and the Control Unit, and the radio communication link between
the devices. The automatic fault diagnosis alarm can also be triggerd by the Intelligent Heat
1. Innohome Stove Guard and how to use it (cont.)
Sound Meaning Course of Action
Control Unit: a short
signal, followed by
a long signal (‘be-
beep’), at approx-
imately 5 second
intervals
The cooker has been turned off due to
the automatic fault diagnosis detecting
a temporary error in the Intelligent Heat
Sensor’s connection to the Control Unit
or in the functioning of a part of the sys-
tem. The automatic fault diagnosis alarm
can also be triggered by the Intelligent
Heat Sensor not being in its original
installation location, or if the Sensor has
not been installed correctly.
First turn all cooker knobs to ‘0’,
then turn off the electricity for
around 15 seconds, using the
main switch. Ensure that the Intel-
ligent Heat Sensor is in its original

STOVE GUARD SGK500 USER MANUAL
Sensor not being in its original installation location, or if the Sensor has not been installed
correctly. If the fault diagnosis detects something abnormal in the functioning of the system,
the Control Unit will emit a fault signal (a short signal, followed by a long signal ‘be-beep’, at
approximately 5 second intervals), and after a minute’s time, it will turn the cooker off.
If the fault diagnosis is signalling, press the Intelligent Heat Sensor cover once during the first
minute of the alarm. If the fault diagnosis alarm was triggered by a temporary glitch or by the
Intelligent Heat Sensor not being in its original installation location, the cooker shutdown will
be prevented and cooking can be continued normally. If the fault diagnosis alarm was caused
by an actual fault situation, the alarm cannot be reset and the cooker is turned off.
If the cooker has been turned o by the fault diagnosis (the Control Unit carries on signalling
the fault alarm signal), it can be turned back on by rst turning all cooker knobs to ‘0’, then by
turning the electricity supply o for 15 seconds, using the main switch. If the fault diagnosis
has detected a problem, rst make sure that the Intelligent Heat Sensor is in its original instal-
lation location. If the automatic fault diagnosis carries on detecting a problem, contact the
product retailer.
For gas/dual- fuel cookers: Refer to the gas kit manual.
1.7 Additional devices
With the Innohome Smart Sockets, additional signalling devices can be joined to the system
or the Stove Guard can be set to automatically operate the extractor fan. Several additional
signalling devices, such as ashing light or vibrating alarms, can be linked and placed around
the house. The extractor fan can be set to automatically turn on when the cooker is used, and to
turn o if the Stove Guard alarm is triggered.
The Control Unit has an external alarm output that enables the alarms to be transferred to social
alarm systems, such as Telecare.
The Intelligent Heat Sensor outlook can be changed with optional colour covers.
See more detailed information about using and installing additional devices from
www.innohome.com.
1. Innohome Stove Guard and how to use it (cont.)
2. Monthly Maintenance
Electric cookers: Since the automatic fault diagnosis tests the Stove Guard operation every
time the cooker is used for cooking, only the Alarm Signal Detection feature needs to be test-
ed on a monthly basis. For the Alarm Signal Detection test, refer to the section 6.2.
Gas/dual-fuel cookers: Refer to the gas kit manual.
Clean the Intelligent Heat Sensor by wiping it with a cloth dampened with a mixture of house-
hold detergent and water. Only use a cloth that does not leave bres.

STOVE GUARD SGK500 USER MANUAL
The Intelligent Heat Sensor is powered by solar panels, using a battery for back-up power. The
working life of the Sensor is at least 15 years, but in practice will be longer, if the solar panels
receive enough light. A low battery in the Intelligent Heat Sensor causes both the Intelligent
Heat Sensor and the Control Unit to emit a signal once a minute. The battery is xed and can-
not be changed. When the Sensor is at the end of its working life, please take care to recycle
the old Sensor appropriately.
The low battery alarm can be postponed for 12 hours by pushing the Intelligent Heat Sensor
cover once. The Control Unit will carry on emitting the battery alarm signal after the Intelligent
Heat Sensor has been removed or its battery has run out. Reset the Control Unit battery signal
by turning the electricity o and then back on using the main switch. An empty battery in the
Intelligent Heat Sensor does not aect the safety features of the Control Unit.
2. Monthly Maintenance (cont.)
3. Low battery alarm
1. Remove the Intelligent Heat Sensor from its packaging and allow about 15 minutes
for it to reach room temperature.
2. The Intelligent Heat Sensor uses dierent settings for electric and gas burners. Carry out
initialization as described below, depending on hob type. If later you wish to change the hob
type setting, see‘Changing the hob type setting’section 7.
Electric burners: Remove the installation plate (1, see image on next page) that covers the
bottom of the Intelligent Heat Sensor by lifting it up. Lifting up the installation plate will also
bring up the battery disconnection piece (2, see image on next page), connecting the battery.
The Intelligent Heat Sensor will emit a signal signifying that the battery is connected. Initialize
the Intelligent Heat Sensor by pressing the cover once. Save the battery disconnection piece
for possible later use..
Gas burners: Remove the installation plate (1, see image on next page) that covers the bot-
tom of the Intelligent Heat Sensor by lifting it up. Lifting up the installation plate will also

piece. Wait that the Sensor emits two signals, then release the
cover. The Intelligent Heat Sensor has now been initialized
and set to gas burners setting. Save the battery disconnec-
tion piece for possible later use..
If the Intelligent Heat Sensor only emits one signal the gas burn-
ers setting was not implemented successfully. In this case see
‘Changing the hob type setting’, section 7.
3. Attach the Intelligent Heat Sensor underneath the cooker
hood with magnets, as close to the central point of the cooker as possible. If the cooker hood
has lights, make sure there is at least 10 cm (4’’) distance between the lights and the Intelli-
gent Heat Sensor. If the magnets do not stick to the hood, the Intelligent Heat Sensor can be
attached using the self-attaching installation plate (1). If using the installation plate, rst make
sure that the attaching surface is cleaned and dry. With gas cookers, the Intelligent Heat Sen-
sor needs to be installed at the minimum height of 65 cm (26’’). If the cooker has no cooker
hood, the Intelligent Heat Sensor can be installed on the wall or if the cooker has a panel on
the back, on the cooker panel. Install the Sensor on the wall using screws (see instructions be-
low), at the height of approx. 40 cm (16’’) above the cooker for electric burners, 65 cm for gas
burners. The Sensor is installed on the cooker panel using a bracket (available separately).
4. The sensitivity level is factory set to suit most installations. However, if the Intelligent Heat
Sensor is installed higher than 65 cm (26’’) for electric burners or higher than 70 cm (28’’) for
gas burners, or if one wants to pre-adjust the sensitivity level to a certain level (when used in
supported housing, for example), set the sensitivity level manually (section 9).

STOVE GUARD SGK500 USER MANUAL
The sensitivity level determines the level of heat and the rate of temperature change required to
trigger an alarm.
The Intelligent Heat Sensor reduces its sensitivity automatically, when the user presses the Intelli-
gent Heat Sensor cover during the Intelligent Heat Sensor pre-alarm signal (see section 1.3). If the
Intelligent Heat Sensor is installed to a cooker hood that is higher than 65 cm (26’’) for electric burn-
ers or higher than 70 cm (28’’) for gas burners, or if one wants to pre-adjust the sensitivity to a certain
level (when used in supported housing, for example), set the sensitivity level manually. Electric bun-
ers: see recommended sensitivity level from the table below. Gas burners: see the table in the gas
installation kit manual. Note that when the Intelligent Heat Sensor is installed on the wall, it needs to
be attached at the height of approx. 40 cm (16’’) for electric burners, 65cm (26’’) for gas burners.
Electric burners sensitivity level. The grey area indicated in the table (30 – 65 cm, 11 - 26’’) shows
where manual setting of the sensitivity level is not required (unless it is pre-adjusted to a certain lev-
el). The level is indicated by the numbers 1 to 16, where 1 represents the most sensitive level, and 16,
the least sensitive. The factory setting is 5.
Setting the sensitivity level manually:
1. Detach the Intelligent Heat Sensor (if attached with screws see‘Detaching an Intelligent Heat Sen-
sor attached with screws’in section 4). Mark the Sensor’s original installation location, if necessary.
Press the Intelligent Heat Sensor cover once.
2. Put the battery disconnection piece into the hole on the bottom surface of the Sensor (2, see im-
age on page 9). Place the Sensor on top of a metallic surface (eg. a cooker), bottom downwards,
for about ve seconds.
3. Remove the battery disconnection piece. The Intelligent Heat Sensor will emit one or two signals
(one if the Sensor has electric burners setting, two if gas burners setting). Save the battery discon-
nection piece for possible later use.
4. Put the Sensor back to its original installation place, unless it is attached with screws in which case
put it on a metallic surface, eg. a cooker.
5. Press the Intelligent Heat Sensor cover for about ve seconds, until you hear a signal.
6. Release the cover and press it again until you hear a signal.
7. Press the cover as many times as is the sensitivity level you want to adjust the Sensor to. Wait that
the Sensor light turns o before pressing again.
8. The Intelligent Heat Sensor will now emit twice as many signals as is the sensitivity level it has
been set to, and a third signal X that gives information to Innohome technical sta. The signals are
given in three lots: 2+2+X for level 2, 3+3+X for level 3, 4+4+X for level 4, and so on.

The alarm output is a 3.5 mm stereo jack found on the Control
Unit. The alarm output is potential free and normally open
(opto). It closes for one second when the Control Unit cuts the
cooker’s gas or electricity supply.
If the alarm output does not work properly, change the polarity
of the cable connecting to the alarm output.

out NO
The cooker has been turned o and no signal sounds
• The Control Unit overheating protection has turned the Control Unit and the cooker o. This has
probably happened due to a wrong installation place that becomes apparent when the cooker is
used on a high power setting. The cooker can be turned back on by turning the electricity o for
a moment using the main switch. If the overheating protection turns the cooker o again change
the Control Unit installation location to a cooler one or to one that has better ventilation.
The Intelligent Heat Sensor alarm sounds in a non-hazardous situation
• When the Intelligent Heat Sensor is rst installed, it needs to adjust to the kitchen environment
and learn the users’ cooking styles. If the Intelligent Heat Sensor starts to signal in a normal cook-
ing situation, press the Sensor cover during the pre-alarm signal. This will cause the Intelligent
Heat Sensor to reduce its sensitivity automatically.
The Intelligent Heat Sensor does not signal when it should
• If the Intelligent Heat Sensor is installed higher than 65 cm for electric burners or higher than
70 cm for gas burners, the sensitivity level needs to initially be set to a more sensitive level (after
which it will sef-adjust to the environment and to the cooking styles of the user(s)). If you are not
certain whether the level was pre-set, set the level again, see section 9.
• If the Intelligent Heat Sensor still does not work, contact the product retailer.
The Control Unit emits a short signal, followed by a long signal (‘be-beep’), at approxi-
mately 5 second intervals
• The automatic fault diagnosis has detected that the Intelligent Heat Sensor is not in its original
installation location, or that there is a problem in the connection between the Intelligent Heat
Sensor and the Control Unit, or in the functioning of some part of the system. The fault diagnosis
alarm can also be triggered by the Intelligent Heat Sensor not being installed correctly. To turn the
cooker back on, rst turn all cooker knobs to ‘0’, then turn the electricity o for about 15 seconds,
using the main switch.

11. Troubleshooting (cont.)
• Ensure that the Intelligent Heat Sensor is in its original installation location.
• If the automatic fault diagnosis carries on nding a problem, contact the product retailer.
The Control Unit signals every hour or half hour
• There has been an error in the identification of the cooker. Repeat the setup procedure in the
following manner; 1) Turn the electricity o for 15 seconds, using the main switch. 2) Let the elec-
tricity be on for 5 seconds. 3) Turn the main switch o again for another 15 seconds. After turning
the electricity back on, the Control Unit will emit a signal signifying that the setup has been com-
pleted. Then carry out the Safety Lock activation/deactivation if applicable (only SGK500-2 in electric
cookers with mechanical knobs excluding cookers with a clock). Activation: Turn any of the hot-
plates on for 5 seconds, then turn it o. Wait until you hear a signal. Deactivation: Turn a hotplate
on, wait until you hear a beep from the Control Unit, then turn it o.
The Control Unit did not identify the alarm signal of the re/CO/gas alarm
• Clean the alarm with a vacuum cleaner.
• Change the batteries in the alarm if necessary.
• Check that the alarm is not located too far from the Control Unit.
The alarms should be located at a maximum distance of 16.5ft (5
metres).
• Adjust the signal recognition frequency by turning the trimmer on
the Control Unit using a screwdriver (frequency adjustment, see the picture). Turn the trimmer
slowly between tests until the Control Unit identies the signal.
The Control Unit responds to other sounds e.g. a telephone ringing or noise from a tele-
vision
• Change the telephone’s ring tone or turn down the volume on the television. If the signal that
causes the false alarm cannot be disabled, adjust the signal recognition frequency by turning the
trimmer on the Control Unit using a screwdriver (frequency adjustment, see picture above): turn
the trimmer slowly, approx. 0.5mm at any one time, then see if the sound still triggers a false alarm.
When a false alarm is no longer triggered, then make sure that the Stove Guard still responds to
the alarm signals of external alarms by re-testing the Alarm Signal Detection feature as advised in
section 6.2.
• It is also possible to disable the Alarm Signal Detection feature, see section 4 ‘Disabling the Alarm
Signal Detection feature’.
Sometimes when a burner is on a low heat setting the cooker lights shut down for a cou-
ple of seconds
• This is a normal function of the Stove Guard. In electric cookers with mechanical knobs (except
cookers with a clock), when a burner is turned on a very low heat, the Stove Guard performs a
check every 15 minutes to see if the cooker is still being used.

The Safety Lock did not activate within 20 minutes
• Check the setting of the Control Unit as advised in section 8. If the Safety Lock was not activated,
redo the setup process as described in section 5.
Intelligent Timer did not cut o the electricity supply in 3 hours
• In some cookers that are operated by touch or that have a clock, and with the SGK500-3 model in
all electric cookers, the Intelligent Timer will not start when a hotplate is on a very low setting.
What to do when changing the cooker to a new one?
• If your hob type has changed (ie. you used to have an electric cooker, and now you have a dual-fu-
el cooker with gas burners) change the hob type setting (see section 7).
• Return the Intelligent Heat Sensor to its factory settings, see section 4. If it is installed higher than
65cm (26’’) for cookers with electric burners or 70cm (28’’) for gas burners, set the sensitivity level
manually (see section 9).
