Programming the extinguishant board
Conventional fire detection control panel
To ensure proper programming of the gas extinguishant system you must:
1. Configure the extinguishant module
2. Program the operating principles
3. Configure the Detection lines and I/O utilized by the extinguishant module
11.1 Configuring the extinguishant module
From panel:
<key>, Programming, Configuration, Acquire int.bus, Ok, Ok
This function allows the control panel to detect the presence of the expansion boards and the extinguishant
module.
11.2 Programming the module
From panel:
<key>, Programming, ExtinguishBoard, Ok
Program the parameters that define the operating principles of the extinguishant system.
11.2.1 Module parameters
Mask zone
Zones that activate extinguish commands when they go into alarm status.
Mode:
At least 1 / 2
/ All
The extinguishant gas release will activate if at least one/two/all of the selected
zones go into alarm status.
Confirm
extinguish
Extinguishant module feature that provides confirmation of extinguishant gas release.
Press the
Ok
button corresponding to the option below.
Do not con-
firm
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
press.
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 extinquish time.
Example: you can connect a pressure gauge to the PRESS. input, or to an input
with the "pressure switch" attribute, that will signal when the cylinders empty
(in order to confirm the successful saturation of the protected space).
Wait for flow
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 an input point set up as a “flow detector”).
EXAMPLE: You can connect a gas-flow signalling 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.
Press the
Ok
button corresponding to the option below.
Supervisory
Activation of the input signals a drop in gas extinguishant pressure.
From pres-
sure
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. If this option is selected, and the
pressure switch activates during control panel standby status, it will trigger a
control panel alarm.
Time pre-
extinction
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 the value is not specified, fire extinguishment will be continue until the control panel
RESET
button is pressed.
