Sensors Parameters

The Touch Point panel supports 3 types of sensors, all of which are equipped with configurable software filter and user offset. Values measured by sensors can be shown on the device’s display (if available) or read through communication protocols.

Information about available sensors can be read from the following register or in the iSMA Configurator:

SENSORS: contains an information about the sensors built-in the panel according to the table below (if the bit is active, it means the sensor is built-in in the panel):

• Modbus register: 30029;
• BACnet object: MSI0, property: Present Value.

Temperature Sensor

A temperature sensor is a standard equipment in the Touch Point panel. The temperature sensor's configuration data is available in the following parameters or in the iSMA Configurator:

TEMPERATURE_SENSOR: indicates a current temperature value with offset;

• Modbus register: 30301;
• BACnet object: AI4, property: Present Value;

TEMPERATURE_SENSOR_OFFSET: allows to set an offset value for the temperature sensor (correction to the temperature sensor's value). The default value is 0;

• Modbus register: 40304;
• BACnet object: AI4, property: 4205;

TEMPERATURE_FILTER: allows to set a filtering value for the temperature sensor (expressed in seconds). The default value is 2 seconds;

• Modbus register: 40307;
• BACnet object: AI4, property: 4003.

Humidity Sensor (Optional)

A humidity sensor is an optional equipment in the Touch Point panel. It is marked with a letter H in a product code, for example: TP-H (means the panel is equipped with a temperature sensor and humidity sensor). The humidity sensor's configuration data is available in the following parameters or in the iSMA Configurator:

HUMIDITY_SENSOR: indicates a current humidity value with offset;

• Modbus register: 30302;
• BACnet object: AI5, property: Present Value;

HUMIDITY_SENSOR_OFFSET: allows to set an offset value for the humidity sensor (correction to the humidity sensor's value). The default value is 0;

• Modbus register: 40305;
• BACnet object: AI5, property: 4205;

HUMIDITY_FILTER: allows to set a filtering value for the humidity sensor (expressed in seconds). The default value is 2 seconds.

• Modbus register: 40308;
• BACnet object: AI5, property: 4205.

CO2 Sensor (Optional)

A CO2 sensor is an optional equipment in the Touch Point panel. It is marked with a letter C in a product code, for example: TP-C (means the panel is equipped with a temperature sensor and CO2 sensor). The CO2 sensor's configuration data is available in the following parameters or in the iSMA Configurator:

CO2_SENSOR: indicates a current CO2 value with offset;

• Modbus register: 30303;
• BACnet object: AI6, property: Present Value;

CO2_OFFSET: allows to set an offset value for the CO2 sensor (correction to the CO2 sensor's value). The default value is 0;

• Modbus register: 40306;
• BACnet object: AI6, property: 4205;

CO2_FILTER: allows to set a filtering value for the CO2 sensor (expressed in seconds). The default value is 2 seconds;

• Modbus register: 40309;
• BACnet object: AI6, property: 4003.
