7.4.3 LOGIC OPERANDS
Two types of operand exist. (Operands are items that can be used within an equation i.e. as
inputs).
The first is an item which requires a further qualifier e.g. Zone
requires a zone number (1-64) and a condition e.g. Alarm. (The zone item and alarm
condition are abbreviated to ZN and Alm in the LCD option menu, but become Z and A when
entered into an equation). Hence, when entering a zone operand, it must be qualified by
entering first the zone number, and then the zone condition e.g. Z14A is zone 14 in alarm.
The second type of operand is a token which needs no further qualification e.g. BLO which is
Battery Voltage Low.
In the following documentation the first type of operand (when qualified e.g. Z1A) and the
second type of operand, are both called "tokens".

Zone (ZN)
Zxxq
where xx = 1 - 64, (see note 1 below), q can be A,F,I,N,D,M,R as follows :
A - Alarm . ^ (Isolated + Auto-reset mode) (i.e. Alarm in a zone which is not
isolated or in Auto-reset mode).
F - Fault . ^ (Isolated + Auto-reset mode).
I - Isolated + Auto-reset mode.
N - Normal - true when none of A, F or I are true.
D - True if the current state of the circuit input is "Detector Operated" (Alarm). I.e.
the voltage is in voltage band B2, or B1 or B3 and these are programmed as
"Alarm". (See note 4 and warning below).
M - True if the current state of the circuit input is "MCP Operated" (Instant Alarm)
i.e. the voltage is in voltage band B1 or B3 and these are programmed as
"Instant Alarm". (See note 4 and warning below).
R - True if a reset is currently being applied to the zone. This is true for the
duration of the 5 second reset applied to the circuit when the zone is reset by
an Operator; for the 5 second AVF reset; and also for the 15 second Auto-
reset mode reset.
Following the reset of a zone there is a 2 second ignore period during which
time this token returns false.
