Associated Receiver or Gateway

RECEIVER (Wireless-to-Analog)
The wireless receiver from BAPI receives the data from one or more wireless sensors. The data is then transferred to the analog output modules and converted to an analog voltage or resistance. The receiver supports up to 32 sensors and up to 127 different analog output modules.

GATEWAY

The wireless gateway receives the data from one or more wireless sensors. The gateway then provides the data to the cloud via MQTT. The gateway also sends a confirmation signal to each sensor upon a successful reception of data. The gateway supports up to 32 sensors.

See BAPI’s gateway instructions on the BAPI website (www.bapihvac.com/wp- content/uploads/50387_Wireless_BLE_Gateway.pdf) to establish communication between the sensors and gateway or the receiver instructions (www.bapihvac.com/wp- content/uploads/50335_Wireless_BLE_Receiver_AOM.pdf) to establish communication between the sensors and receiver

Initial Activation

For convenience, BAPI recommends pairing the sensor to the intended receiver or gateway prior to mounting either device. Both devices need to be powered-on to pair. See the receiver or gateway installation manual for instructions on pairing the sensor.

Battery Power Units

The unit comes with two preinstalled batteries. To activate the unit, remove the base plate and pull out the two battery insulator tabs as shown in Fig. 2. Press the Service button and the Service LED should flash once to confirm power. If the sensor will not be commissioned for more than a couple of days, BAPI recommends reinstalling both battery insulator tabs to conserve battery life.

Wire Power Units

Wired power units have a power terminal block near the top center of the unit. To activate the unit, apply 9 to 30 VDC (50 mA max) or 15 to 28 VAC (50 mA max) as shown in Fig. 3. Press the Service button and the Service LED should flash once to confirm power.

Drywall Mounting

1. Place the base plate vertically against the wall where you want to mount the sensor and mark the two mounting holes.
2. Drill two 3/16” (4.8mm) holes in the center of each marked mounting hole. Insert a drywall anchor into each hole.
3. Secure the base to the drywall anchors using the #6 x 1” (25mm) mounting screws provided.
4. Attach Cover by latching it to the top of the base, rotating the cover down and snapping it into place. Secure the cover by backing out the lock-down screw using a 1/16” (1.6mm) Allen wrench until it is flush with the bottom of the cover.

Operation

Power the unit as described in “Initial Activation” section. Follow the gateway or receiver instructions for pairing the unit and changing the adjustable settings. (The instructions are available on the BAPI website.)

Wireless Sensor Reset

Sensors remain paired to the gateway or receiver and output modules when power is interrupted or the batteries are removed. To break the bonds between them, the sensors need to be reset. To do this, press and hold the “Service Button” on the sensor for about 30 seconds. During those 30 seconds, the green LED will be off for about 5 seconds, then flash slowly, then begin flashing rapidly. When the rapid flashing stops, the reset is complete. The sensor can now be paired to a new receiver or gateway. To re-pair to the same receiver or gateway, you must reset the receiver or gateway. Output modules that were previously paired to the sensor do not need to be re-paired.

Onboard Memory

Sensor retains up to 16,000 readings should the communication become interrupted. The sensor only stores readings from missed transmissions and only when the sensor is paired to a gateway. Once communication is re- established with the gateway, the stored readings are transmitted and then erased from the sensor. The current reading and nine previous readings are sent at each transmit interval until the sensor is caught up. Temporarilyshortening the transmit interval will allow the sensor to more quickly clear any stored readings.

Battery Replacement

1. Remove the cover from the base plate by turning in the cover lockdown screw with a 1/16” (1.6mm) Allen wrench until the covercan be removed.
2. Remove the used batteries from their holders and discard in an environmentally safe manner. Replace with new batteries in the correct orientation (Fig 6).
3. Attach Cover by latching it to the top of the base, rotating the cover down and snapping it into place. Secure the cover by backing out the lock-down screw using a 1/16” (1.6mm) Allen wrench until it is flush with the bottom of the cover.
