System Components SB-ECM Module
Ch-4 Automatic Input Off
When this input is active, activation of the discharge sequence is possible only by using the manual
discharge button. In this state, the automatic alarm does not trigger activation of the discharge
sequence.
Ch-5 Low Cylinder Pressure (PSL)
When this input is activated, the module sends the control panel a fault signal indicating low cylin-
der pressure.
Ch-6 System Tripped (PSH)
When this input is activated, the module permanently activates the outputs configured as visual sig-
nals (TO).
Ch-7-8 Automatic Inputs 1-2
Activation of these inputs in rest condition, with Automatic inputs off and discharge inhibition dis-
abled, starts the automatic discharge sequence (activated). If during panel programming both inputs
are defined, the automatic discharge sequence will be triggered only if both inputs active. If during
panel programming only one input is defined, the automatic discharge sequence will be triggered
by the activation of the defined input. It is also possible to activate the automatic discharge
sequence using virtual 15 simply by defining it during configuration. This makes it possible to acti-
vate the automatic discharge sequence from detection systems outside the module. In this phase,
activation of automatic discharge can occur only if the module is connected to the control panel.
Ch-9-10 EV Outputs
When configured, these outputs are activated once the discharge delay time has elapsed and cause
the release of the extinguishing agent in the protected area.
Ch-11-12 EV/TOA/TO Outputs
These outputs can be configured individually during programming as EV, TOA, or TO.
If configured as EV, activation occurs as with channels 9 and 10.
If configured as TOA, these outputs are managed as follows:
NOTE: Activation of this input in rest condition immediately triggers continuous activation of the
outputs configured as TO and TOA.
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 the active condition before the configured reset inhibition time
has elapsed.
NOTE: Enabling of the EV outputs during the presence of an alarm cause the discharge of the
extinguishing agent only when the set discharge activation delay time has elapsed.
