CNPP acquires a new test tunnel dedicated to fire detectors
To meet the requirements of European standards dedicated to fire detectors, CNPP has acquired a new, latest-generation test tunnel.
Fire detectors tested in the latest generation tunnel
To meet the growth of its activities and the objective of modernizing its test benches, CNPP Fire Electronic Laboratory has recently equipped itself with a new modern and versatile test tunnel. This equipment specifically dedicated to the evaluation of fire detection systems conforms to the EN54 series of standards, which establishes the criteria, evaluation procedures and performance for the elements making up the alarm and fire detection systems.
What are the specific features of this test tunnel ?
Designed to meet the requirements of EN 54-7 and EN 54-5, which relate to spot smoke and heat detectors, used in fire safety systems fitted to buildings. This tunnel also meets the standard EN 14604 for household smoke detectors.
Essentially used for certification processes and conformity tests (CE/RPC marking, NF, etc.), this test tunnel allows the performance evaluation of fire detectors, thus ensuring their reliability and accuracy in the early detection of fires.
The detectors are subjected to various test conditions, including controlled variations in smoke concentration, temperature rises and other parameters related to fire detection.
What are the specific features of this test tunnel ?
The automation of this new test tunnel optimizes testing by reducing the manual interventions of technicians. By way of example, the rotation support is motorized to allow the rotation of the detector and the tests can be sequenced.
In addition, a cooling unit makes it possible to perform tests at temperatures below the atmosphere, thus significantly reducing the cooling times between two heat detection tests. Finally, the heated inner walls guarantee a homogeneous distribution of the temperature inside the tunnel.
