All processing of the functions necessary for the electrical control of the fire extinguishing installation shall be carried out by the e.c.d..

The e.c.d. shall be able to carry out the following compulsory functions (see also Figure 1):

1. Reception and processing of at least one input fingering signal from an f.d.a.s. and an input triggering signal from manual triggering device(s) connected directly to the e.c.d. (see also 4.4);

2. On receipt of the input triggering signal(s), transmission of the extinguishing signal (see also 4.5, 4.3.2 g) and 4.17);

3. On receipt of the input triggering signal(s) activation of alarm devices (see also 4.6);

4. Indication of each condition unambiguously e.g. activated condition, fault warning condition (see also 4.7 to 4.16);

5. Transmission of the information of the incorrect status of components as specified in 4.19 (monitoring), if provided, and of the information of the fault warning condition (see also 4.14 and 4.19);

6. Transmission of the information of the released condition (see also 4.11);
