10.2 Producing a Zone Latching Sequence

1. Create an initiating device. This can be a monitor zone, input circuit, or a status such as

All Call.

2. Create a non-latching zone such as a monitor zone. This will be used as the "Latching"

zone.

3. Highlight the "Latching" zone, and select the Advanced logic tab.

4. Create an equation that will activate the "Latching" zone by the initiating zone, input, or

status OR by the "Latching" zone itself.

Advanced Logic Equation shown for the "Latching" zone, 01-00-**-IZ-011

**-**-**-SW-017 OR 01-00-**-IZ-011

**-**-**-SW-017 – All Call Common switch

01-00-**-IZ-011 – Latching Zone

The Latching Zone, 01-00-**-IZ-011, will latch once the All Call switch is activated. If the

All Call is restored, the latch will remain latched until a system reset is initiated.
