The OneVue Differential Pressure Sensor is equipped with an optional door switch monitoring feature.
This feature is designed to monitor whether a door in the room being monitored is open or closed - eliminating false alarms when a door is intentionally left open for an extended period of time signaling that the room is not in use.
When a door status change is detected, the sensor device automatically transmits the door status to OneVue. To enable the door monitoring feature, the device door jumper must be enabled (jumper removed) and a magnetic door switch is required to be wired to the device door terminal block. By factory default, the door monitoring feature is disabled.
The door monitoring feature is designed to allow the status of a magnetic door switch to manage when a monitored room is set to the Alarms Disabled state. During the Alarms Disabled state, OneVue does not monitor the differential pressure sensor readings or the sensor device operating status and will not generate alerts for the Monitored Asset (room).
Use of this feature eliminates manually setting the Monitored Asset in your OneVue account to a Suspended state when a room is not in use and is not required to be monitored. When a room is not in use, you can simply open the door to disable the monitoring of the room's differential pressure. For door switch monitoring, it's recommended to supply AC-power to the sensor device and apply battery power for backup power purposes only.
When an Open status is detected, the sensor device automatically transmits an Open status to OneVue and the sensor status is set to Open.
When the door switch has remained in an Open status for longer than the time period set in the sensor's Door Delay setting, the sensor and its assigned Monitored Asset (room) is automatically set to an Alarms Disabled state with a status of Past Door Delay.
During the Alarms Disabled state, the sensor device continues to transmit its readings and operating statuses, but the data is only logged and stored in your OneVue account. The system does not monitor the sensor readings or device operating status and disables the alerts assigned to the Monitored Asset during the Alarms Disabled state.
When the door switch changes from an Open status to a Closed status, the device automatically transmits the Closed status to your OneVue account. The sensor and its Monitored Asset (room) are then set to a Normal state and the system begins to monitor the sensor readings and device operating conditions.
