Numbering the field devices
After installation, all the field devices must be numbered as follows:
1.
Attach a clearly visible label to each detector and write a progressive identification
name on each one, from 1 to N, where N is the number of detectors installed. The
numbering criteria is at operator's discretion (for example, the detectors can be grouped
by type, by zone or any other way)
2.
Apply the same number identification procedure to the relay modules (MAR40), the
display modules (MDD40) and the alarm modules (MID40). In each case, numbers
begin from 1 (one), like for the detectors.
Fig. 3.15 – Identifying the field devices
Below is an example table that can be used to input all the data indicated above. It may
need to be extended for large systems, if it is too small.
The alarm modules can be seen as detectors since each of the four inputs must be
configured (using DIP switches) as a pre-alarm, a threshold one alarm or a threshold two
alarm.
At the AM level, again by DIP switches, it is possible to configure the nature of the input
signal between steady and pulsed, the latter necessary for acquisition of push buttons.
