5.1.1 Inputs List
The Inputs list is a list of all inputs that you can use in equations. The inputs are:
• Local input circuits
• Local input zones
• Remote input zones
• Custom Intervals
• Custom Timers
• Switches
As per UL 864 and UL 2572, the use of Custom Timers which would delay the operation of
Input Zones or Outputs is not permissible.
The columns in the Inputs list are ID, Node, Type, and Tag.
• ID: This column displays IDs for all inputs. IDs aid in identifying the input. IDs have the
following structure:
Node Number-CPU Number-Loop Number-Circuit Type-Circuit Number
Node Number – The two-digit number assigned to the node.
CPU Number – The two-digit number assigned to the node’s CPU.
Loop Number – The two-digit number assigned to the loop the device is on, if
applicable.
Circuit Type – The two-letter code that identifies the type of circuit. This is used to
distinguish between an input circuit, zone, interval, timer, and status. The circuit type
uses the following abbreviations:
IT – Interval
ST – System status
SW – Switch
TM – Timer
ZS – Zone switch
NS – Node status
IZ – Input zone
IN – Input circuit
Circuit Number – The three-digit number assigned to each status, switch, timer,
interval, zone or input.
A double asterisk (**) appears if there is no applicable value for certain components,
such as a Loop Number for a system status.
• Node: This column displays the node number of each input device or zone. Global
inputs, such as system statuses, control switches, timers, and intervals, have no node
number.
• Type: This column identifies the type of input. Inputs can be intervals, system statuses,
switches, timers, zone switches, node statuses, input zones, and input circuits.
• Tag: This column displays a description of each input.
