● The HOA module can be used to override outputs and monitor inputs.
● The HOA mapping and definition of a logical point in the database can be done in
any order.
● The HOA is hot-swappable. The module can be installed without powering down
the controller and interrupting facility operations.
● The HOA module can also be remote mounted on the inside or outside of an
enclosure door, using an optional accessory sold separately.
The firmware provides a default HOA switch assignment based on the type of the host
field panel. There are new menus available that allow for the identification of what HOA
module is connected and communicating, along with the ability to view and customize
the HOA switch mapping.
