REPLACING THE SENSOR ELEMENT

The Hansen Gas Detectors come with a pre-calibrated

sensor elements which maintain the sensor’s gas

type and calibration information. Replacement

sensor elements come pre-calibrated as well for the

refrigerant type and calibration level. To replace the

gas detector’s sensor element:

1. Power-down the gas detector.
2. Using a 5/32” (4mm) hex key/ allen wrench (not

included), remove the lid and disconnect the

ribbon cable from the sensor element.
3. Remove installed sensor element from lid by

holding onto the housing and turning counter

clockwise 90°. Take care not to apply excessive

force to the sensor element’s circuit board. When

the square tab of the sensor housing is aligned

with the lock icon, firmly pull the module to

remove it from the housing.
4. Install the new sensor element by aligning the

square tab with the lock icon before firmly

pressing it into the enclosure. Taking care not to

apply excessive force to the sensor element’s

circuit board, rotate the sensor element clockwise

90° (or until the triangle icon aligns with the lock

icon on the lid).
5. Connect the ribbon cable (to the sensor element

and transmitter) and close the lid.
6. Ensure gasket is aligned correctly and tighten

the lid using the supplied hardware in an “X”

pattern. Tightening torque should be limited to

hand tight and should be uniform.
7. Power-up the gas detector.
8. After start-up sequence has finished, check

sensor response (bump test).

RESET SYSTEM TO FACTORY DEFAULT
SETTINGS

To reset system to factory defaults, remove lid and

hold TACT#1 and TACT#2 simultaneously for 30

seconds. Instrument will restart to confirm factory reset.

Alarm Delay

A time delay for the operation of the relay and alarm

horn can be adjusted.

Alarm Buzzer

Alarm Buzzer can be reconfigured to up to 15 minute

delay. Alarm Buzzer is >72dB at 4 default factory

setting is enabbled, with option to disable

BLUETOOTH INSTRUCTIONS

The Hansen Gas Detector has a Bluetooth® feature to

allow a smartphone to communicate with the individual

detector. This feature allows the user to confirm the

target gas, the target gas level, log the sensor readings,

and initiate calibration/bump tests. To start this option,

user would need to download the Hansen Gas Detector

App from either Google Play Store or Apple Store.

SENSOR SETUP

In order to utilize the Bluetooth® option, sensors will

need to be setup individually thru the APP. To do this:

1. Enable Bluetooth® discovery by tapping MAG#1

for 1-second. After 10-seconds, device will indicate

that it is discoverable with audible heartbeat until

it has been paired, discovery has timed-out or has

been cancelled
2. Launch the Hansen Gas Detector APP and click the

Bluetooth® icon at the bottom of the screen to

initiate a scan
