
Ch-12 EV-Reserve/TOA/TO Output
This output can be configured during programming as EV-Reserve, TOA or TO.
If configured as EV-Reserve, activation occurs as with channel 10.
If configured as TOA or as TO, these outputs are managed as those in Type-1 embedded logic.
Type-3 Embedded Logic
This type of embedded logic is typical of extinguishing systems with a main discharge and a sec-
ondary discharge, typical of CO
2 systems. 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 following exceptions:
 Ch-1 Primary Discharge Input
Activation of this input in normal condition triggers the start of the main manual discharge
sequence. The logic executed following activation of this input, when another automatic sequence
is in progress, depends on the manual discharge mode set for this input during configuration.
 Ch-5 Secondary Discharge Input
Activation of this input triggers the immediate activation of the outputs configured as EV-Second-
ary. The outputs are activated only under all of the following conditions:
• The primary extinguishing sequence has been completed (Released)
• The TOA sound devices have not been silenced
• The reset command has not been executed by the panel (Reset)
 Ch-9 EV-Primary Output
This output is activated once the discharge delay time has elapsed and triggers the discharge of the
primary extinguishing agent in the protected area.
 Ch-10 EV-Secondary Output
This output is activated immediately following activation of the Secondary Discharge input. The
output is activated only under all of the following conditions:
• The primary extinguishing sequence has been completed (Released)
• The TOA sound devices have not been silenced
NOTE: Manual discharge mode: Determines manual discharge input operation during an
automatic discharge sequence:
n-DO: Activation of the manual discharge button does not cancel the delay in progress due to
automatic discharge
y-DO: Activation of the manual discharge button cancels the delay in progress due to automatic
discharge
NOTE: Once manual discharge has been activated, it is no longer possible to disable
the channels in the extinguishing area.
NOTE: It is not possible to reset this output before the configured reset inhibition time has
elapsed.
NOTE: Enabling of the EV-Primary outputs in the presence of an alarm causes the discharge of
the extinguishing agent only when the set discharge activation delay time has elapsed.
