DocumentDocument1. Short description TSM400-1-CP is a multi-parameter sensor that supports the 1-Wire protocol. The sensor measures the concentration of carbon dioxide and atmospheric pressure. Both basic sensor elements, for carbon dioxide and pressure, used in the device are digital. This ensures high measurement accuracy and longterm stability. The basic sensing element for atmospheric pressure is factory calibrated and it does not require any lifetime recalibration. Automatic calibration is available for carbon dioxide measurements. TSH400-1-CP is housed in a slim plastic enclosure. The bottom part of the enclosure is suitable for installation on standard flush-mounted/cavity wall boxes ø68mm, with installation openings on 61mm. 2.

Pinout Pin 1-W +5÷30V GND Description 1-Wire data Positive power supply Ground (negative) supply A+ BTERM Not used Not used Not used UTP wires color Green Orange Green/White tracer Orange/White Tracer 6. Installation It is strongly recommended to use UTP/FTP cables and daisy-chained (linear) topology for multiple sensors and keep the total cable length up to 30 meters. Attention! Due to the high peak current, only one TSM400-1-CP sensor can be connected to a controller. The length of the cable between the controller and the sensor should not exceed 10 meters. If you want to connect more than one TSM400-1-CP sensor, please contact your supplier for technical guidance. "Star" topology can be used only as a last resort for up to 4 sensors and a total cable length of up to 10 meters. 7. Status indicator The status of the device is shown by a single LED, located inside the box: · If the LED blinks for a period of 1 second, the sensor works properly; · If the LED blinks for a period of 3 seconds, there isn`t communication with the controller; · If the LED doesn't blink, there isn't a power supply.

The tips below will ensure good measuring results: · The sensor shall be installed about 1.2-1.4 m above the floor; · To avoid solar radiation, the sensor should not be installed next to windows or directly in the sunlight; · The sensors shall be installed in a place with sufficient air circulation. 1-Wire is a registered trademark of Maxim Integrated Products, Inc. It is strongly recommended to read Maxim's 1-Wire tips at http://www.maxim-ic.com/appnotes/index.mvp/id/148. TSM400-1-CP sensor is intended for installation on a cavity wall box with 68mm diameter and 61 mm screw spacing. 9. Firmware update The firmware of the sensor can be updated with any Teracom controller which supports a 1-Wire interface.
