If an alarm condition occurs, all active TIM devices will be deactivated. All TIM equations will be ignored until all alarms are restored,
at which point all TIM devices will return to their proper state.
A.3 Operators
OR
Operator: The first (and most useful) operator is OR.
Equation: OR(Z9 Z15 Z23)
If ANY one of the three operands in the equation are in alarm, then the control mod-
ule will be activated.

IF Software Zone 15 is in alarm OR
IF Software Zone 23 is in alarm,
THEN this control module will be activated.
AND
Operator: The AND operator requires that each operand be in alarm.
Equation: AND(Z9 Z15 Z23)
ALL three operands in the equation MUST be in alarm for the control module
to be activated.
IF Software Zone 9 is in alarm AND
IF Software Zone 15 is in alarm AND
IF Software Zone 23 is in alarm,

NOTE:
Software Zone 240 is used to activate FSCS mode priority for AM2020/AFP1010 Revision 4.0
Software or later. Once this zone is activated, subsequent automatic events will be locked out. Smoke control
operation can only be overridden manually. Each smoke detector input that will lock out the system must be
mapped to Z240. Inputs that should not activate lockout, such as pull stations, should not be mapped to Zone
240.
