Boolean Equations for Mass Notification
7.1.1 Device Status
The Device Status allows a user to apply a mask to any device. Masks include:
“:A" – Alarm
“:B” – Bypass
“:F” – Fault
“:L” – Level
If a mask is applied to a device then the equation will only become TRUE when the specific
status changes. For Example “07-02-01-IZ-001:B”, this alarm zone will only become TRUE
when this zone is bypassed.
To apply a mask, use the drop down and select the desired mask before moving the input into
the Equation Dialog Box. If no mask is applied, any change in status will result in the equation
becoming TRUE.
7.1.2 Eligible Input List
A list of all eligible inputs that can be referenced by equations. The list consists of local input
circuits and zones, remote zones, intervals, timers, and switches.
The ID column lists identification values for all eligible inputs. An ID is assigned to each input,
interval, timer, or switch to aid in identification when referenced in the equation dialog. The
address of each is used to structure the ID.
The ID is structured in the following manner:
Node No._CPU No._Loop No._CKt Type_CKt No.
Node No. – The numerical value assigned to the node.
CPU No. – The numerical value assigned to the CPU within the node
Loop No. – The numerical value assigned to the SLC where the device is physically
connected, if applicable
CKt Type – The circuit type. This is used to distinguish between an input circuit, zone, interval,
timer or status. The following are the abbreviations used for each circuit type:
IN – Input circuit
IZ – Input zone
SW – Switch
ST – System status
IT – Interval
TM – Timer
