| Property | Value | Description |
|---|---|---|
| Closed State | open or closed |
Defines the normal state of the designated input to match the requirements of the sensor device. |
| Status | read-only | Indicates the current state of the sensor (Locked or Unlocked), and its status {ok}, or other possibilities. |
| Door Held Open Limit | minutes and seconds | Defines the length of time that the door is allowed to be held open before the system generates an alarm. |
| Debounce Time | None (no debounce time used), minutes and seconds (0 minutes to 59 minutes); defaults to 1 second | Minimizes Door Forced alarms around the time of a validation, exit request activation, or manual door override. The intent is to prevent unwanted Door Forced alarms caused by a door bouncing open momentarily just after or just prior to an authorized entry. Two scenarios use this property.In the first scenario, a bounce after open or close occurs when a legitimate open or close is followed by slamming the door, which bounces it open momentarily causing a forced-door alarm. Setting a debounce time allows time for a bounce to occur without creating an alarm. In the second scenario, a bounced door can be quickly followed by a legitimate opening when a person attempts to open a door and the door slips out and closes momentarily before the person opens it fully. A bounce closed is not counted if it is less than the debounce time. |
