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:
othe ambient temperature is between -10°C and +50°C.
othe 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:
oSituations, in which there is heavy condensation.
oSituations, in which aggressive gases are present.
oSituations, in which dust or steam is present.
oSituations, in which obstructions could hinder the flow of air to the fire detectors.
oAreas 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:
oDismantling the housing.
oImpacts 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:
oa visual check for dirt and mechanical damage to the fire detector.
oa 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!
