Overview
Honeywell 2106B1822 Nitrogen Dioxide Sensor 2106B1822
The Unit should be fitted to a suitable junction box appropriate to the rating of the area where it will be installed. The sensors should be fitted to a tapped hole within the enclosure. Cabling should be multicore, two wires plus screen, conductor size 14AWG (2.5mm2)max.2106B1822 Nitrogen Dioxide Suitable conduit should be used appropriate to the rating of the area where the unit is installed, e.g. Class I Div. 2. Please refer to local and national electrical regulations. Sensors are supplied
pre-calibrated.
The apparatus should be installed in a location free from dusts and direct heat sources. For optimum protection against water ingress ensure that the sensor is installed facing downwards.Installation is to be performed by a qualified installation engineer,with the power to the unit disconnected.2106B1822 Nitrogen Dioxide For oxygen versions, remove the neoprene stopper and snap the RFI screen and internal hydrophobic assembly (supplied
separately) into place (page 9).See the technical handbook for details of installation in a duct or in
forced air conditions.

Sensepoint for toxic gas detection is supplied pre‑calibrated,however, for increased accuracy in specific applications, on‑site calibration is recommended.Re‑calibration should only be attempted by qualified service personnel. Calibration should only be attempted after the sensor has been installed and powered for a time exceeding the warm up time (Table 1).First zero the control system with no gas present on the sensor. 2106B1822 Nitrogen Dioxide If target gas is suspected to be in the vicinity of Sensepoint, flow clean
air over the sensor using a flow housing (see below).Fit a flow housing and connect a cylinder of either air, for a zero, or a known concentration of gas (approximately 50% FSD) to the flow housing using nylon or PTFE tubing. Tubing lengths should be kept to a minimum to avoid extending the speed of response. 2106B1822 Nitrogen Dioxide Connect the outlet of the flow housing to a safe exhaust area. Pass the gas through the flow housing at a flow rate of approximately 1 l to 1.5 l per minute.

Allow the sensor to stabilise. When gassing with air, adjust thecontrol card to indicate zero. For span, the control card should
be adjusted to indicate the concentration of the target gas being
applied. Remove the flow housing and the gas supply.
Note: for oxygen, the span gas is normally air at 20.8%vF%7B0XCAB)LKNIT0K@G.gif)
O2
. The Honeywell 2106B1822 Nitrogen Dioxide Sensor 2106B1822
control card should be adjusted to indicate this when the
sensor is in either clean ambient air, or in a flow of 20.8%v
O2 in nitrogen from a cylinder. A zero adjustment is not
normally required, however it is recommended that the alarm
levels are tested using a cylinder of a lower concentration of
oxygen in nitrogen.
See Table 1 for details of concentrations and times to be used. If
the controller cannot be spanned, consult the technical handbook.
For calibration using the Weather Protection in high flow
applications refer to the technical handbook.
