3-wire 4-20 mA Source
This covers connection to gas detectors such as Sensepoint Plus/Pro.
1 Set up the gas detector.
Refer to the detector’s user manual for details describing how to set up the detector. 
2 Check that all power and electrical connections to the controller, and electrical 
connections to the gas detector are correct.
For gas detector access see its user manual. For detector to controller wiring details see
page 20.
3Follow step 2 on page 57.
4 For Sensepoint Plus/Pro check for a minimum voltage of 12 Vdc at the gas 
detector.
For detectors other than Sensepoint Plus/Pro refer to their operating instructions.
5 Check that Touchpoint 4’s display shows the correct gas units and range for the 
detector in use.
If not follow the procedure on page 52 to change the gas units and range.
6Follow step 5 on page 58, to step 16 on page 59.

WARNINGS
Touchpoint 4 is designed for installation and use in indoor safe area 
non-explosive atmospheres. Installation must be in accordance 
with the recognized standards of the 
appropriate authority in the country concerned.
Before carrying out any work ensure local regulations and site procedures 
are followed. 
Access to the interior of the controller, when carrying out any work, 
must only be conducted by trained personnel. Switch off and isolate 
the power supply to the controller when access is required. 
Take any necessary precautions to prevent false alarms.
The detectors/sensors that the controller connects to may be used for gas 
detection in hazardous atmospheres. Refer to the individual detector/sensor 
instructions for their details. 
This chapter details the following:
• general maintenance
• troubleshooting, see page 62
• system configuration sheet, see page 63
• system review check sheet, see page 64
General Maintenance
Honeywell Analytics recommend that the controller’s configuration and operation are checked
annually using the two check sheets shown at the end of this section. 
The System Configuration Sheet should be referenced during system checks and updated if
any changes to the system configuration have been made as well as a calibration log. 
The System Review Check Sheet contains a list of the minimum checks that should be made
to ensure the proper and safe functioning of a system.
The gas detectors connected to the controller should be checked by following the procedures
detailed in their user guides.
