When some zones are in alarm, a condition of
pre-activation is signalled by the Control panel by
means of the ON Pre. Ext., which flashes quickly.

Pre-Extinguishment Time This field will allow you to
program a delay between verification of the Activation
Mode conditions and activation of the Electrovalve out
-
put ([EV] terminals). The Pre-Extinguishment output
([PR] terminals) will be active during the Pre-Extingui-
shment Time.
Accepted values: 0 to 60 seconds, in steps of 1 second.
Default value: 20 seconds.
Extinguishment Time This field will allow you to set
the Extinguishment Time. If you DISABLE the Bistable
option, the EV output will restore to standby when the
programmed Extinguishment Time expires.
Accepted values: 0 to 300 seconds (5 minutes ) in steps
of 5 second.
Bistable If you ENABLE the Bistable option, the EV
output will restore to standby when the Control panel
Resets.
Manual Pre-Extinguishment Time Set the time that
must elapse from the point at which the EM Input is acti
-
vated to the point at which the Electrovalve Output ([EV]
terminals) are activated. During the Manual Pre-Extin
-
guishment Tim e, the Pre-Extinguishment Output
([PR] terminals) is activated.
Accepted values: 0 to 60 seconds, steps of 1 second.
Default value: 0 seconds.
Manual Pre-Extinguishment When the Manual
Pre-Extinguishment option is enabled, the Manual
Pre-Extinguishment Time may be set. When the option
is disabled, the Pre-Extinguishment Time will also be
used by the Control panel for manual activation.
Reset Inhibit Time This is the amount of time that
must elapse from the point at which the Extinguishment
Module is enabled to the point at which the module may
be reset. If the reset is performed during the Reset Inhi
-
bit Time, the Control panel will reset all systems (except
for the activated Extinguishment Module) for a few se
-
conds, after which it will return to an alarm condition.
Accepted values: 0 to 30 minutes, steps of 1 minute.
Default value: 0 minutes.

Manual Extinguishment Input
This field will allow you to set up the Standby status of
the Manual Extinguishment Input ([EM] terminals).
Normally Closed If this option is DISABLED (at Defa
-
ult), there must be a 3900 ohm resistance across the [+]
and [–] terminals of the EM Input during Standby status.
When this option is enabled, the resistor in standby
must be 680 ohm.
n
Disable Extinguishment Input
This field will allow you to set up the Standby status of
the Disable Extinguishment Input ([IE] terminals).
Normally Closed If this option is DISABLED (at Defa-
ult), there must be a 3900 ohm resistance across the [+]
and [–] terminals of the IE input during Standby status.
When this option is enabled, the resistor in standby
must be 680 ohm.
n Pressure Switch Input
This field will allow you to set up the Standby status of
the Pressure Switch Input ([PS] terminals).
Normally Closed If this option is DISABLED (at Defa
-
ult), there must be a 3900 ohm resistance across the [+]
and [–] terminals of the PS input during Standby status.
When this option is enabled, the resistor in standby
must be 680 ohm.

ü Enrol the Power Supply Stations (if installed).
A tick (þ) indicates that the respective Power Supply
Station is part of the system.
Description This 16 character field will allow you to as

example, it may be useful to assign the name of the
area where the device is located. The assigned label
