12.3.1 Gas Concentration Priority Logic
This setting allows you to configure the number of channels that are required to trigger this
priority based on gas concentration level, set allow remote disable and/or remote override
and set a timer (JTimer) that will escalate the event to a higher priority if required.
Use the - and + buttons to ensure Gas Concentration is showing.
Priority:
Choose a priority number that will be assigned to the channels that you want to
assign the Gas Concentration Priority to.
Qty:
Select the channel quantity (0 to the number of channels that will have that priority).
This is the number of channels that need to be in alarm before the priority will be
triggered.
DRE:
(DRE = Disable Remote Enable) Choose On to allow remote disable and Off to
disable remote enable. If the gas detection system is not connected to a remote interface
such as a DDC, BAS, FIRE PANEL etc., the flag should be set to Off. If set to On, it means
the priorities can be enabled from a remote device (such as a BAS or DDC system).
ORE:
(ORE = Override Remote Enable). If set to On means the remote enable can be
overridden.
J Level:
Specify which priority level to jump forward to if the length of time set in JTimer
runs out.
JTimer:
Specify the length of time in seconds (0 to 30,000 / 500 minutes maximum)
before the priority escalates to the next level.
The J Level and JTimer can be used to trigger additional actions if the first priority has
not generated resolution to the alarm condition. The priority being jumped to normally will
not monitor any channels but will be assigned to a Relay or Strobe or Audible or Analog
Output. The timer will normally be set to a value large enough to give the first priority time to
complete or resolve the cause of the issue. The jump to priority is used as an escalation tool.
