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.
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.
For door switch monitoring, it's recommended to supply AC-power to the sensor device and apply battery power for backup power purposes only.
Remove the device cover; simultaneously press the two tabs located on the top side of the device.
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.
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.
Remove the jumper from the lower circuit board. Move the jumper to one pin only on jumper block to retain the jumper.
Wire the two door switch wires to the 2-pin terminal block header by loosening the lock down screws on the header. Insert the wires and tighten the screws to secure the wires.
Reinsert the terminal block header to the receptacle on the lower circuit board.
Reinstall the bottom plate containing the dual port sensor by routing the door switch wires trough the wire slot on the bottom plate cover – make sure to reattach connecting cable to dual port sensor if previously removed. Applying slight outward pressure on the sides of the sensor housing allows bottom plate to slide in. Make sure the bottom plate slides into the retention tab slots on the housing.
Reattach the device cover.
The sensor device is now configured to monitor the door status set by the magnetic door switch.
