Abstract

The invention relates to a detection system employed for securing a start-up of an application, said system comprising at least one first detector (D2) and one second detector (D3), each detector comprising two input terminals (I1, I2) connected to its logic inputs, two output terminals (O1, O2) connected to its logic outputs and two power supply terminals (0V, +24V) connected to two electrical power supply lines. The two output terminals (O1, O2) of the first detector (D2) are connected to the two input terminals (I1, I2) of the second detector (D3) and the two output terminals (O1, O2) of the second detector (D3) are connected to control devices (K1, K2) of the application to be secured, so as to form a detection chain.
