User manual HONEYWELL C7110A1010 DATASHEET

[. . . ] It detects unpleasant odors, tobacco smoke, and vapors emitted by such materials as furniture, carpets, paint, glue, etc. As proven in practice, this device detects those substances typically present in air having a poor quality, some of which may otherwise go undetected by room occupants, themselves. This sensor has proven itself in numerous applications over many years. [. . . ] The cover of the air quality sensor is fixed by a tab on the underside of the unit; to disassemble the cover and the sub-base, see Fig. To access all of the mounting holes, pull off the perforated cover, bend down slightly the tab to release the printed circuit board, and leverage the printed circuit board out (see Fig. 3). INCREASING OUTPUT VOLTAGE LIFT INCREASING GAS CONCENTRATION 2 Fig. Output voltage as a function of gas concentration INSTALLATION Wiring All wiring must comply with local electrical codes and ordinances or as specified on installation wiring diagrams. Wall module wiring can be sized from 16 to 22 AWG (1. 5 to 0. 34 mm2), depending on the application. The maximum length of wire from a device to a wall module is 1000 ft (305 m). Twisted pair wire is recommended for wire runs longer than 100 ft (30. 5 m). Keep wiring at least one ft (305 mm) away from large inductive loads such as motors, line starters, lighting ballast, and large power distribution panels. Run wall module wiring separately from 50 Vac or greater power wiring. 1 PRESS Fig. a) Mount the sensor onto the wall outlet box, or b) bore wall holes as specified in Fig. 3 and mount the wall module with appropriate screws. CAUTION Low Voltage Equipment. The 24 Vac power source for this product must be a safety isolating transformer. A transformer that is CE certified and meets the Low Voltage Device (LVD) requirements must be used in Europe for all installations of this product.

After re-inserting the printed circuit board and the perforated plate, connect the wires to the terminal block as follows: a) Strip 3/16 in. Adjust the trimming potentiometer (see section "Adjusting the Offset Signal"). When the air quality deteriorates, the voltage of the output signal will rise. Adjusting the Offset Signal After mounting the device, the output signal should be adjusted in accordance with expected ambient conditions and individual preferences. The output signal is adjusted using the trimming potentiometer located on the sensor board (see Fig. [. . . ] NOTE: When first operating the device or after the device has been powered down for more than 4 weeks (e. g. , during storage), the output signal may vary during the first 48 hours of operation. In this case, you should verify the output signal after 48 hours of operation.
