System Components SB-ECM Module
Ch-15 Virtual automatic Input
Activation of this virtual input triggers the automatic discharge sequence (activated).
Type-2 Embedded Logic
This type of embedded logic is typical of extinguishing systems with two groups of cylinders
(main/reserve). The logic used by the module in this mode complies with EN 12094 standards. The
15 module channels carry out the same functions as those in Type-1 embedded logic, with the fol-
lowing exceptions:
Ch-5 Main/Reserve input
When this input is inactive, the extinguishing/release command will be carried out by the output
channels configured as EV-Main. When this input is active, the extinguishing/ release command
will be carried out by the channels configured as EV-Reserve.
Ch-9 EV-Main output
This output is activated once the discharge delay time has elapsed if the Main/Reserve input is
inactive, and actuate the solenoid valves of the main set of extinguishing agent in the protected
area.
Ch-10 EV-Reserve Output
This output is activated once the discharge delay time has elapsed if the Main/Reserve input is
active , and actuate the solenoid valves of the reserve set of extinguishing agent in the protected
area.
Ch-11 EV-Main/TOA/TO Output
This output can be configured during programming as EV-Main, TOA or TO.
If configured as EV-Main, activation occurs as with channel 9.
If configured as TOA or as TO, these outputs are managed as with Type-1 embedded logic.
NOTE: Once automatic discharge is activated it will no longer be possible to disable the ECM
module channels from the control panel.
NOTE: It is not possible to reset the active condition before the configured reset inhibition time
has elapsed.
NOTE: It is not possible to reset this output before the configured reset inhibition time has
elapsed.
NOTE: Enabling of the EV-Main outputs in the presence of an alarm causes the discharge of the
extinguishing agent only when the set discharge activation delay time has elapsed.
NOTE: It is not possible to reset this output before the configured reset inhibition time has
elapsed.
NOTE: Enabling of the EV-Reserve outputs in the presence of an alarm causes the discharge of
the extinguishing agent only when the set discharge activation delay time has elapsed.
