15.2.6 Reset inhibit time
It is a requirement of the extinguishing control panel standard EN12094-1 to inhibit reset of the system after it
has been activated until there is a signal representing the end of the discharge (a released input) or for an
adjustable time period of up to 30 minutes. The factory default for the reset inhibit time is 0.
To change the reset inhibit time, switch on the enable controls keyswitch and slide the write enable switch on the
module to be configured gently to the left. Press the ENTER button on the extinguishing module then press the UP
button until the display shows:
RESET INHIBIT
TIME = 0
Press the ENTER button and the display will show:
RESET INHIBIT
TIME = 0 ? To change the reset inhibit time, press the UP or DOWN buttons until the time
required is displayed and then press ENTER.
To save the settings, slide the write enable switch gently to the right.
Resetting of the extinguishing module after it has been activated will now be prohibited until the set reset inhibit
time.
15.2.7 Pre-release delay time
The extinguishing control panel standard EN12094-1 allows for a time delay to be set from activation of the
extinguishing module to operation of the extinguishing release output. This time may be between 0 and 60
seconds with a maximum of 5 second steps.
The factory default time delay on the Sigma XT+ extinguishing modules is 30 seconds.
To change the pre release delay time, switch on the enable controls keyswitch and slide the write enable switch on
the module to be configured gently to the left. Press the ENTER button on the extinguishing module then press the
UP button until the display shows:
pre-rel delay
TIME = 30 sec. Press the ENTER button and the display will show:
pre-rel delay
TIME = 30 sec.? To change the time, press the UP or DOWN buttons until the required time is
displayed.
To save the settings, slide the write enable switch gently to the right.
The pre=release delay time will now be set to the chosen value.
15.2.8 Output 2 delay
If the configured extinguishing output mode is Common (rather than MAIN/RESERVE), it is possible to set
extinguishing output 2 to have a further delay of up to 10 minutes in steps of 1 minute.
Extinguishing output 2 delay timer will be started when extinguishing output 1 is asserted.
This could be used to provide an additional discharge of extinguishing agent to maintain concentration for a longer
period of time.
Output 2 Delay
TIME = 00 min. Press the ENTER button and the display will show:
Output 2 Delay
TIME = 00 min.? To change the time, press the UP or DOWN buttons until the required time is
displayed
To save the settings, slide the write enable switch gently to the right.
The extinguishing release time will now be set to the chosen value.
Note: This option is available only on modules fitted with firmware version 1.59 or higher.
15.2.9 Extinguishant release time
The time that the extinguishant output is active for can be set between 60 and 300 seconds. The factory default
time for this is 60 seconds. It is also possible to disable this timer such that the extinguishant outputs remain
active until the module is reset. See Release timer menu option section 15.2.12.
To change the extinguishant release time, switch on the enable controls keyswitch and slide the write enable
switch on the module to be configured gently to the left. Press the ENTER button on the extinguishing module then
press the UP button until the display shows:
EXTING. RELEASE
TIME = 60 sec. Press the ENTER button and the display will show:
