Extinguishment Module Terminals
EM Supervised/Bypassable Manual Extingui-
shment Input
This Input is for manual activation of the Extingui-
shment devices.
Standby status of this Input can be either Normally
Open (at default) or Normally Closed (refer to “Manual
Extinguishment Input” under “Enrolling: Extinguishment
Modules” in the “PROGRAMMING FROM PC”)
Operating principles:
Ø
the Control panel will consider the EM Input OPEN
when a 3.900 ohm resistance is applied to its [+] and
[–] terminals;
Ø
the Control panel will consider the EM Input CLOSED
when one or more (up to 10) 680 ohm resistor is/are
applied in parallel to the 3.900 ohm resistance.
The EM Input will activate when inverse conditions to its
standby conditions occur.
Activation of the EM Input will start the Pre-Extingui-
shment Time.
Activation of the EM Input will be indicated by Glowing
on the ON Manual Ext. LED.
Short-circuit or power supply interruption on the EM
Input will be indicated by fast blinking on the Fault Ma-
nual Ext. LED.
The EM input can be disabled by means of the Disable
Manual Extinguish. key.
Disablement of this Input will be indicated by Glowing
on the Disable Manual Extinguish. LED.
IE Supervised Inhibit Extinguishment Input
This Input is for the inhibition of Extinguishment devices.
The standby status of this Input can be either Normally
Open (at default) or Normally Closed (refer to “Disable
Extinguishment Input” under “Enrolling: Extinguishment
Modules” in the “PROGRAMMING FROM A PC”).
Operating principles:
Ø
the Control panel will consider the IE Input OPEN
when a 3.900 ohm resistor is applied between its [+]
and [–] terminals;
Ø
the Control panel will consider the IE Input CLOSED
when one or more (up to 10) 680 ohm resistor is/are
applied in parallel to the 3.900 ohm resistor.
The IE Input will activate when the inverse conditions to
its programmed standby conditions occur.
Activation of the IE Input will start the Pre-Extingui-
shment Time.
If the IE Input is active when Extinguishment conditions
occur, the Control panel will activate the PR Output
(Pre-Extinguishment) but WILL NOT START the
Pre-Extinguishment Time.
If the IE Input activates during the Pre-Extinguishment
phase, the Control panel will stop Pre-Extinguishment
Time. The Control panel will restart the Pre-Extingui-
shment Time when the IE Input restores to standby.
If the IE Input is activated during the Extinguishment
phase, the Control panel will reset the EV Output (Elec-
trovalve). The Control panel will re-activate the EV Out-
put when the IE Input restores to standby.
Activation of the IE Input will be indicated by Glowing on
the ON Disab. Ext. LED.
Short-circuit or power supply interruption on the IE Input will
be indicated by fast blinking on the Fault Disab. Ext. LED.
PS Supervised Pressure Switch Input
This Input is for the Pressure Switch connection.
Standby status of this Input can be either Normally
Open (at default) or Normally Closed (refer to “Pres-
sure Switch Input” under “Enrolling: Extinguishment
Modules” in the “PROGRAMMING FROM A PC”).
Ø
the Control panel will consider the PS Input OPEN
when a 3.900 ohm resistor is applied across its [+]
and [–] terminals;
Ø
the Control panel will consider the PS Input CLOSED
when one or more (up to 10) 680 ohm resistor is/are
applied in parallel to the 3.900 ohm resistor.
The PS Input will activate when the inverse conditions
to its programmed standby conditions occur.
Activation of the PS Input will be indicated by Glowing
on the ON Pres. Switch LED.
Short-circuit or power supply interruption on the PS
Input will be indicated by fast blinking on the Fault Pres.
Switch LED.
If the Pressure Switch Input of an Extinguishment Modu-
le is activated during or after the Extinguishment phase,
and the respective Extinguishment Confirmation op-
tion is ENABLED (refer to “Pressure Switch Input” under
“Enrolling: Extinguishment Modules” in the “PRO-
GRAMMING FROM A PC” section), the Control panel
will activate the AE Output (Activated Extinguishment).
EV Supervised Electrovalve Output
This Output is for the Electrovalve connection.
Operating principles:
Ø
in Standby status, the EV terminals will be OPEN;
Ø
during the Extinguishment phase, the EV terminals
will be CLOSED.
Activation of the EV Output will be indicated by Glowing
on the ON Electrovalve LED.
Short-circuit or power supply interruption on the EV
Output will be indicated by fast blinking on the Fault
Electrovalve LED.
Up to 5 A can circulate on the EV Output.
24P Power Boost Input
This Input is for the Power boost required by the devi-
ces connected to Outputs PR and AE.
Wiring instructions:
Connect the [+] and [–] terminals of this Input to the [+]
and [–] terminals 47 of the Switching Power Supply.
PR Supervised Pre-Extinguishment Output
This Output is for Pre-Extinguishment signalling.
Operating principles
Ø
Standby status: negative pull-down to 0 V on the [+]
terminal; positive pull-up to 27.6 V on the [–] terminal.
Ø
Pre-Extinguishment phase: positive pull-up to 27.6 V
on the [+] terminal; negative pull-down to 0 V on the
[–] terminal.
Activation of the PR Output will be indicated by Glowing
on the ON Pre Ext. LED.
Short-circuit or power supply interruption on the PR Input
will be indicated by fast blinking on the Fault Pre Ext. LED.
Up to 1 A can circulate on the PR Output.
