Programming the extinguishant module
Installation and programming manual
To ensure proper programming of the gas extinguishant system you must:
1. Configure the extinguishant module
2. Program the operating principles
3. Program the input and output extinction points
12.1
Configuring the extinguishant module
From panel:
<key>, Programming, Configuration, BUS, Extinguish board, Ok
This option allows the panel to determine how many extinguishant modules are connected (this model
accepts one module only).
12.2
Programming the module
From panel:
<key>, Programming, ExtinguishBoard, Ok
Program the parameters that define the operating principles of the system.
12.2.1 Parameters
Mask zone
Zones that will activate the fire extinguishant system if one (or more) of their input points
goes into alarm status.
Mode:
At least 1: If you select this mode, only one of the selected zones need be in alarm status in
order to activate the fire extinguishant system.
At least 2: If you select this mode, at least 2 of the selected zones must be in alarm status in
order to activate the fire extinguishant system.
ALL: If you select this mode, ALL the selected zones must be in alarm status in order to
activate the fire extinguishant system.
Confirm
extinguish
Extinguishant module feature that provides confirmation of extinguishant gas release.
Do not confirm
If an “Extinguish” event occurs, the extinguishment module will activate the VALVE output
(for the pre-set time) and the RELEASED output without awaiting confirmation of
extinguishant gas release.
Wait for pressure
switch
The RELEASED output will be activated when the
Extinguish time
expires, that is, if the
“pressure switch” signal has been activated (from the pressure switch input or from an point
set up as a “pressure switch” input). The “pressure switch” signal will be considered valid only
when the signal persists after expiry of the Extinguish time.
EXAMPLE: You can connect a pressure-drop signaling device to the PRESS. input or an input
point set up as a “pressure switch” (the device will signal when the cylinders empty thus
confirming that the protected space has been successfully saturated).
Wait for flow
detector
The RELEASED output will be activated when the
Extinguish time
expires, that is, if the
“from flow detector” signal has been activated during this phase (from the pressure switch
input or from a point set up as a “flow detector” input).
EXAMPLE: You can connect a gas-flow signaling device to the PRESS input or a point set up as
a “flow detector” input (the device will signal when gas is being released).
Pressure switch
Defines the significance of the signal coming from the PRESS input.
Supervisory
: activation of the input signals a drop in gas extinguishant pressure.
From pressure
: activation of the input indicates that the gas cylinders are empty, therefore,
the protected space is saturated and activates the “confirm extinction from pressure switch”
signal.
From flow detector
: activation of the input indicates that gas has been released and
activates the “confirm extinction from flow detector” signal.
Pre-extinguish
Time
Duration of the automatic
Pre-extinguish Time
, activated by a zone in alarm status.
Extinguish Time
Length of time the electrovalve remains active, starting from the end of the pre-extinguish
phase. If this value is not defined, the extinction phase will last until a “stop extinction”
command is received (from a STOP-EXT input, or point programmed as “stop ext.”
or from a
button on the panel) or until the
RESET
button is pressed.
