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 - 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 sensor's device door jumper must be enabled (jumper removed) and a magnetic door switch is required to be wired to the sensor door terminal block. By factory default, the door monitoring feature is disabled. For door switch monitoring, it's recommended to supply AC power to the sensor device and apply battery power for backup power purposes only.
The Differential Pressure Sensor door monitoring feature is designed to allow the status of a magnetic door switch and the sensor's Door Delay setting time period to manage when a monitored asset is set to the Alarms Disabled state. When set to the Alarms Disabled state, OneVue does not monitor the differential pressure readings or the sensor device operating status and will not generate alerts for the Monitored Asset.
Use of this feature eliminates manually setting the Monitored Asset 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.
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 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. OneVue 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 OneVue. 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.
