information relating to its operation and use. Always observe all safety instructions. If you have
any questions or are uncertain regarding the use of this product seek specialist advice, refer to
our internet side at www.dexaplan.com or contact the service office. Keep these instructions in
a safe place and provide them to any third party who may require the information.
Proper use
This heat detector is intended for use indoors within private households. At a tempera-
ture above approx 60 °C the heat detector will sound a 85 dB(A) loud alarm signal, as a
warning in case of fire.
Install heat detectors in areas in which dust, steam or cooking fumes could cause a
false alarm from a smoke detector, for example in the kitchen, and possibly also in the
cellar, laundry room and garage. Heat detectors must not be used in place of smoke
detectors in escape routes, living rooms or bedrooms. Observe local building regula-
tions. In general smoke detectors react to fire quicker than heat detectors, therefore
smoke detectors must be installed appropriately, especially in the hallway outside the
room in which a heat detector is installed. Without the additional protection of smoke
detectors, heat detectors will not provide adequate protection in case of fire.
The heat detector is powered by a 9 V block battery. The heat detector will only
function when a correct and good condition battery is correctly inserted. Do not use
rechargeable batteries.
Unless there is a legal responsibility, no liability will be accepted for any damages in
particular to persons or property caused by non-functioning or incorrect functioning of
the heat detector.
Smoke and heat detectors are no substitute for your duty of supervision and care, and are
no substitute for property or life insurance. You are responsible for provision of adequate
insurance cover. No liability for damages will be accepted in case of fire or false alarm.
This heat detector is not suitable for persons with impaired hearing. Replace the heat
detector within 10 years from the date of manufacture.

Safety instructions
The following instructions are for your own safety when installing and operating the
heat detector. Please note that non-compliance with these safety instructions leads to a
serious risk of danger.
m
Danger to life and risk of injury!
•
Do not leave small children unsupervised with the packaging material,
the device or with any small parts. Danger to life from suffocation!
•
Do not damage any gas, electricity or telecommunication lines when
fitting the device. Danger to life, risk of injury and damage!
•
Ensure that the battery is inserted with the correct polarity. Ensure that the
battery is not short circuited or exposed to excessive heat such as sunshine
or fire. The battery must also never be recharged. Danger to life from explosion!
•
Make sure that your hearing is not exposed to the loud alarm signal for any length
of time and that the signal is not triggered close to the ears. This can cause serious
damage to hearing.
•
Leaking or damaged batteries can cause acid burns if they come into
contact with the skin. Always use suitable protective gloves when handling.
•
Never attempt to repair the device yourself. Otherwise there is a risk of damage to
the device and of improper functioning. The guarantee will also be invalid.
•
Do not paint or apply any covering over the heat detector otherwise the function
will be impaired!
•
Do not use an open flame to test the heat detector. Otherwise there is a
risk to life and of damage through fire!
Preparation in case of fire
•
Draw up an emergency escape plan by drawing the escape routes on a floor plan
of your home. Draw at least two escape routes from every bedroom.
•
Discuss the emergency escape plan with all family members / occupants. Child-
ren will often hide when they are unsure of what action to take. Practice your
escape routine together.
•
Familiarise all family members with the alarm sounds of the heat and smoke detec-
tors. They must be prepared for fire and must know what action they should take.
•
Determine a place outside your home for a meeting point. This way you can
check if all persons have left the building.
•
Ask your fire brigade for advice about fire extinguishers and fire blankets and their
use, and also about how you can best protect yourself against the danger of fire.
What to do in case of fire?
•
Never use water to extinguish a chip-pan or deep-fat fryer fire as this causes an
explosion. Use a fire blanket to cut off the oxygen supply to the flames.
•
Alert all occupants.
•
Keep calm and avoid panic. Follow your emergency escape plan. Your safe
escape depends on clear thinking and remembering what you have practiced.
•
Leave the house as quickly as possible using the safest exit. Do not waste time
getting dressed or collecting valuables. Do not use lifts.
•
Close all doors behind yourself in order to slow down the spread of the fire.
•
If you have to cross a smoke filled room, keep your head as low as possible. Hold a
(preferably damp) cloth in front of your mouth.
•
Feel doors before opening them.
- if these are warm, it is possible they are holding back the fire. Try to find an
alternative escape route.
- if the surface of the door is cool, then hold your shoulder against the door and
open it carefully a few centimetres.
If you can see smoke or flames then close the door.
•
Call the fire brigade as soon as you have left the house. Give your exact address
and wait at the roadside until the fire brigade arrives.
•
Do not return into a burning house.
Where to locate
o
Install the heat detector in areas in which dust, steam or cooking fumes could
cause a false alarm from a smoke detector, for example in the kitchen, and
possibly also in the cellar, laundry room and garage. The heat detector must not
be used in place of a smoke detector in escape routes, living rooms or bedrooms.
Observe local building regulations. In general smoke detectors react to fire quicker
than heat detectors, therefore smoke detectors must be installed appropriately,
especially in the hallway outside the room in which the heat detector is installed.
o
Check that the alarm sound is loud enough in the bedrooms to wake occupants
in the case of fire.
o
The heat detector must be installed on the ceiling, as close to the centre of the
room as possible. The distance to each wall must not exceed 5,3 m. The distance
between two heat detectors within a room should not exceed 5,3 m. In larger
rooms the installation of additional heat detectors may be necessary.
o
The distance to walls and corners must not be less then 30 cm.
o
A closed door or other obstacles will block heat from the device and reduce the
audibility of the alarm sound. Install an adequate number of detectors.
o
The heat detector must be easily accessible for testing and battery replacement.
o
For complicated or larger dwellings seek advice from a fire safety specialist or
from the fire brigade.
