The sensor is encapsulated in a 0.25”O.D. 304 stainless steel probe with various probe lengths (4”, 6”, 8”, 12”, 18”) for single point duct temperature monitoring. ACI’s mesh network Series 2000 wireless sensors utilize reliable Spread Spectrum Radio technology. They can be installed easily in minutes eliminating hundreds of feet of wire and saving installation cost while reducing installation labor risks. The Series 2000 sensor Data-Link LED confirms the data transmission was received by the receiver for fast and reliable positioning of the sensor during installation. There is no need for special wireless installation equipment or tool. Together with the ACI Series 2000 receivers and controllers, the ACI wireless sensors can be used with any LON, BacNet, MODbus, or DDC control system or panel. The maximum radio transmission distance is dependent on the building type. The maximum open air transmission distance is one mile. In a typical commercial building with steel I-Beam construction, concrete floors with reinforcing rod, and metal stud walls, it can be expected that transmissions will penetrate vertically through floors and horizontally through 200 to 500 feet of walls, furniture and air. Installation Wireless sensors should be installed within 200 to 500 feet of the receiver. RR2552 signal repeaters can be installed as to increase transmission distance between sensors and receivers. CAUTION Observe battery polarity when installing battery. To select the proper sensor location, first install and power the receiver. To activate the sensor insert the battery observing the polarity. The mesh networked Series 2000 system does not require any additional wireless equipment to determine the proper location of the sensors. While the sensor is attempting to connect to the receiver the Data-Link LED will blink rapidly 8–10 times every 10 seconds. Once a connection has been established the Data-Link LED will blink once to indicate the data transmission has been received successfully. The Data-Link LED will continue to blink once for every data transmission. The data transmission rate is programmed into the sensor (normally 1 minute intervals). To manually initiate a data transmission press the push button switch located by the negative terminal of the battery. Install the duct sensor through a 1” opening in the side of the duct. Since the sensor is located at the tip of the probe, consideration should be made to place the tip of the probe in the middle of the airflow. Mount the plastic housing of the sensor onto the duct work using four (4) sheet metal screws. Locate the sensor at a straight section of the duct and away from heating, cooling or humidifying elements. Locate and record the sensor TXID numbers located on a label on the inside of the enclosure cover. The sensor has a Low Battery LED that will start to blink continuously when the battery voltage is low. A low battery signal is also sent to the receiver for remote indication that the battery should be replaced. If the battery is not replaced in approximately 2 months the battery voltage will become so low that the Low Battery and Data-Link LEDs will not blink. Replace the battery and the Data-Link LED will start blinking while the sensor is re-establishing communications with the receiver. Attach the cover of the duct sensor by installing the four screws to complete the installation. !
