Mercury points properties
This extension is the container for all proxy points that represent real-time data originating from the Mercury panel(s).
This includes virtual points.
Types of points
Two types of points are supported:
- Portal points represent “real” proxy points that are associated with devices.
- Virtual points represent “logical” points used to communicate with the Mercury panel(s).
Portal points
Points properties describe the proxy points that relate to portal events.
| Type | Value | Description |
|---|---|---|
| IsLatched | Default: true or false | This is a state of the locking device for a portal. It means that the portal is in a locked position. |
| IsOpen | Default: true or false | This means that a door is normally open. It does not indicate an alarm state. |
| IsAccessOverridden | Default: true or false | This is a state of the door in which normal access control has been suspended. A door in this state may be latched or unlatched. The purpose of this state is to keep the door either latched or unlatched until the IsAccessOverridden state is released. |
| IsMasked | Default: true or false | This is a state in which normal reporting of state changes is suspended. A portal or an input point may be masked for alarm events. If a portal or an input point is masked, it is not monitored, and it will not generate alarm events. A portal may be in one of two states: monitored or masked. By default, ,state has a value of “Masked.” |
| IsTampered | Default: true or false | |
| IsForcedOpen | Default: true or false | |
| IsHeldOpen | Default: true or false | |
| IsDeviceInAlarm | Default: true or false | Indicates that the input is in an alarm condition. An input may not be able to function correctly. An audible signal may indicating an alarm condition that requires immediate attention, such as an alarm initiated from an intrusion detector, door switch, or the like. |
Virtual points
Each pair of points is associated with an alarm proxy point in the BAS. An input proxy point reports the state of the device represented by the proxy point to the Mercury panel and an output virtual point communicates the acknowledgment from the Mercury panel back to the NiagaraAX station.
| Type | Value | Description |
|---|---|---|
| Facets | Default: true or false | Changing Facets may help to explain how these points are used. |
| Proxy Ext | Multiple properties | These properties are standard Niagara properties. For more information, see ProxyExt Properties (module://docDrivers/doc/aProxyExtProperties.html) in the NiagaraAX Drivers Guide (module://docDrivers/doc/index.html). |
| Out | Indicates the current status of the virtual point. |
