2.3. Guideline for the installation of sensors and bases or fire detectors
− Make sure that fire detectors are installed according to the applicable building
regulations and standards.
− Sensor and base combinations should only be installed where:
o the ambient temperature is between -10°C and +50°C.
o the condensation and humidity values are between 10% and 95% RH – non-
condensing (at 40°C).
− Only install fire detectors in suitable environments.
− The following environments should be avoided:
o Situations, in which there is heavy condensation.
o Situations, in which aggressive gases are present.
o Situations, in which dust or steam is present.
o Situations, in which obstructions could hinder the flow of air to the fire detectors.
o Areas at risk of explosion.
− Do not use high-voltage testers on the sensor or the base.
− Certain actions can lead to permanent damage to the sensor:
o Dismantling the housing.
o Impacts or shocks.
2.4. Testing the fire detectors
− If damage to a fire detector is suspected, it is to be replaced.
− After installation, all fire detectors in the fire alarm system are to be tested to ensure
that all function correctly.
− Installation and maintenance should only be carried out by appropriately trained
specialist personnel.
− Do not test the function of fire detectors with a flame or open fire.
− Functional tests should be performed with appropriately configured sensor test devices
in order to be able to determine correct functioning.
− Maintenance must be carried out after a testing period specified by the regulations of
the person responsible for the fire detector system.
− If no such regulations are available, we recommend annual testing. In this case, the
following tests are to be included:
o a visual check for dirt and mechanical damage to the fire detector.
o a normal function test with smoke detector and/or heat detector test devices.
− Sensors are delivered with a dust protection cover to keep out dirt during installation.
This is only to be removed after installation!
