5.1.2 Device Status
The Device Status menu applies a status (also called a mask) to an input. If you apply a
status to an input, then the equation becomes true when the input has that status.
The statuses are:
:A – Alarm
:B – Bypass
:F – Fault
:L – Level (used with 4-20 mA input modules)
For example:
• The equation 07-02-01-IZ-001:B is true only when this zone is bypassed.
• The equation 01-00-02-IN-001:A is true only when this input device is in alarm.
If you do not apply a Device Status to an input, any change in the input’s status results in the
equation becoming true. For example, the equation 01-00-02-IN-002 (a single input device
with no Device Status) is true whenever this input device changes status.
To apply a Device Status
1. Click a Device Status in the pulldown menu.
2. Double-click the input in the Inputs list.
The input and the Device Status appear in the Equation box.
5.1.3 Operators
Operators are the operations that you apply to the inputs in the equation. The operators are:
AND Syntax: input AND input
An equation with AND is true only if both inputs are true. For example, the
equation 01-00-02-IN-001:A AND 01-00-02-IN-002:A is true only if both input
01-00-02-IN-001 and input 01-00-02-IN-002 are in alarm.
This equation can turn on a relay if a smoke detector in the lobby is in alarm, but
not if the smoke detector in the elevator machine room is detecting smoke.
OR Syntax: input OR input
An equation with OR is true if either input is true. For example, the equation 01-
00-02-IN-001:A OR 01-00-02-IN-002:A is true if either input 01-00-02-IN-001 or
input 01-00-02-IN-002 is in alarm.
NOT Syntax: NOT input
An equation with NOT is true only if the following input is not true.
For example, the equation NOT 01-00-02-IN-001:A is true only if input 01-00-
02-IN-001 is not in alarm.
The equation 01-00-L2-SM-001:A AND NOT 01-00-L2-SM-002:A is true if the
first input (01-00-L2-SM-001) is in alarm, and the second input (01-00-L2-SM-
002) is not in alarm.
