49799 Wireless Duct Temperature Sensor
Product Information
The Wireless Duct Temperature Sensor is a device designed for
monitoring and transmitting temperature data from ducts. It is
equipped with adjustable settings and onboard memory. The sensor
can transmit data to a digital Gateway or a wireless-to-analog
Receiver.
The sensor is compatible with BAPI’s wireless devices and can be
field adjusted to suit the installation requirements. All settings
can be configured using the gateway or receiver. For more detailed
information on adjusting the settings, refer to the gateway or
receiver instructions available on the BAPI website.
Associated Receiver or Gateway
Receiver (Wireless-to-Analog): The wireless
receiver receives data from one or more wireless sensors. It
transfers the data to analog output modules and converts it into 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 data
from one or more wireless sensors. It provides the data to the
cloud via MQTT and sends a confirmation signal to each sensor upon
successful reception of data. The gateway supports up to 32
sensors.
To establish communication between the sensors and the gateway
or receiver, refer to BAPI’s Wireless Quick Start Guide or the
gateway/receiver instructions on the BAPI website.
Initial Activation
Battery Power Units: The unit comes with two
pre-installed batteries. To activate the unit, follow these
steps:
- Open the cover to access the batteries.
- Remove the battery tab insulators.
- Press the Service button, and the Service LED should flash once
to confirm power.
Wire Power Units: To activate the unit, follow
these steps:
- Open the cover to access the circuit board.
- Apply 9 to 30 VDC or 24 VAC to the power terminals as
shown. - Press the Service button, and the Service LED should flash once
to confirm power.
Mounting
To achieve the best temperature reading, follow these steps for
mounting the sensor:
- Place the sensor in the middle of the duct, away from
temperature stratified air, coils, or humidifiers. - Drill the probe hole as shown in Fig 3. Use the enclosure tabs
to mark the pilot hole locations and drill 1/8 (3.2mm) pilot
holes. - Mount the enclosure to the duct using the provided mounting
screws. - Tighten the screws until the foam backing is depressed slightly
to prevent air leakage.
Note: Do not drill into the enclosure, as it will violate the
NEMA and IP rating.
Product Usage Instructions
Operation:
1. Power the unit as described in the Initial Activation
section.
2. Follow the gateway or receiver instructions for pairing the
unit and changing adjustable settings. Refer to the instructions
available on the BAPI website.
3. Pressing the Service button on the circuit board will force a
transmission.

Overview and Identification
User adjustable settings Onboard memory Transmits to a digital Gateway or a wireless-to-analog
Receiver
BAPI’s Duct Wireless Sensor measures the temperature and transmits the data via Bluetooth Low Energy to a receiver or gateway. This unit features a rugged IP66-rated BAPI-Box enclosure and ¼” (6.4mm) stainless steel probe with standard probe lengths from 4″ to 18″ (102 to 457mm).
Duct Temperature Sensor
Adjustable Settings
BAPI’s wireless devices have several settings that can be can be field adjusted to suit the needs of the installation. All settings are configured by either the gateway or the receiver. (See the gateway or receiver instructions documents available on the BAPI website for more information on adjusting the settings.)
Sample Rate/Interval The time between when the sensor wakes up and takes a reading. The available values are 10 sec, 30 sec, 1 min, 3 min or 5 min with the gateway, or 30 sec, 1 min, 3 min or 5 min with the receiver.
Transmit Rate/Interval The time between when the sensor transmits the readings to the gateway or receiver. The available values are 30 sec, 1, 2, 3, 4, 5, 10, 15, 20 or 30 minutes, or 1, 6 or 12 hours with the gateway, or 1, 5, 10 or 30 minutes with the receiver.
Delta Temperature The change in temperature between sample intervals that will cause the sensor to override the transmit interval and transmit the changed temperature at the next sample interval. The available values are 0.1, 0.2, 0.3, 0.4, 0.5, 1, 2, 3, 4, 5 °F or °C with the gateway, and 1 or 3 °F or °C with the receiver.
Temperature Min/Max The maximum or minumum temperature that will cause the sensor to override the transmit interval and immediately transmit a reading to the gateway. (Only available when using a gateway.)
Temperature Offset Adjusts the temperature value being transmitted to match that of a calibrated reference device. The available values are ±0.1, 0.2, 0.5, 1, 2, 3, 4 or 5 °F or °C. (Only available when using a gateway.)

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.
Battery Replacement
Open the cover to access the batteries (Fig 6).
Remove the batteries from their holders and discard in an environmentally safe manner. Replace with new batteries in the correct orientation.
Battery Specifications: Two 3.6V Lithium batteries: (#14505, 14500 or equivalent)
Remove and replace batteries
in the correct orientation as
shown.
