Alarm module (MID40)
The Alarm modules are used for remote monitoring of alarms present in the system and
detectable via digital input.
Each module has four independent inputs for tension-free contacts that can be either
latched (switch) or not latched (button).
Each input has an alarm type assigned to it in order to activate any RMs assigned to it.
The type of input contact (latched/button) is selected through a way of the 4-way SW1
DIP switch (SW1.1 for input 1 and so forth, as shown in Fig. 11.4).
The type of alarm to assign to each input is selected through SW2 DIP switch (one pair
for each input: SW2.1 and SW2.2 for input 1 and so on, as shown in Fig. 11.4); the
possible types of alarm are:
Pre-alarm
