Differential Pressure Install: Enable door switch monitoring
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 status change is
detected, the sensor device automatically transmits the door status to OneVue.
Use door switch monitoring to manage when monitoring is enabled or disabled
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.
Enable door switch monitoring
To enable the door monitoring feature, the device door jumper must be enabled (jumper removed) and a door switch is
required to be wired to the device door terminal block. By factory default, the door monitoring feature is disabled.
IMPORTANT
For door switch monitoring, it's recommended to supply AC power to the sensor device and apply
battery power for backup power purposes only.
1.
Remove the device cover; simultaneously press the two tabs located on the top side of the device.
2.
Remove the bottom plate containing the dual port sensor by applying slight outward pressure on the sides of the
sensor housing to allow the bottom plate to slide out. It's recommended to disconnect the cable connection to the
dual port sensor and note the cable orientation and pin connection.
3.
Remove the 2-pin terminal block located on the edge of the lower circuit board. The use of needle nose pliers can
be used to pull off the terminal block header.
4.
Remove the jumper from the lower circuit board. Move the jumper to one pin only on jumper block to retain the
jumper.
