Zero and Span 
This menu is for calibrating the controller measurements to the connected gas detector. 
1 Access the menu system and select the   menu option.
Press Up or Down. The icon flashes.
2 Press OK.
The top left of the display reads CO to indicate the set zero menu mode. The gas reading
displays the current real zero value.
Note Ensure the sensor is in clean air before carrying out the next step. For oxygen 
apply nitrogen to the sensor at 0.3 l/min.
3 When the gas reading is stable adjust the reading to zero.
Use the Up/Down buttons. 
Note Honeywell Analytics recommend the use of half full-scale gas for calibration 
purposes (contact a distributor for the supply of calibration gas).  4 Press OK when the reading is zero. 
The display now shows a 10 second countdown. 
When the countdown is complete the display shows GOOD if the zero
has succeeded and then change to the span mode. 
If the zero fails the display shows FA I L  and returns to the beginning of
the set zero mode.
After successfully setting the zero the display then changes to show CS
in the top left to indicate the set span mode. 
For O

Alternatively press Cancel to by-pass   the zeroing and move directly to
the span function.
5 Fit a flow adapter to the gas detector sensor.
First remove any accessory fitted to the sensor, e.g. weather protection.
6 Apply calibration (span) gas to the detector at a flow rate of 0.3 l/min. 
The gas reading on the controller display shows the measured reading
from the detector
7 When the gas reading is stable adjust the reading to the actual 
concentration of the calibration gas being applied to the detector. 
Use the Up/Down buttons.
8 Press OK. 
The display then shows a 10 second countdown. 
When the countdown is complete the display shows GOOD if the span
has succeedd. 
If the span fails the display shows FA I L and returns to the beginning of
the span menu.

Alarm Levels and Relay Action 
Sets the alarm levels for Alarm 1 and Alarm 2 as well as how the alarm relays operate. For oxygen
either a Rising (oxygen enrichment) or Falling (oxygen deficiency) alarm can be selected.
The display changes to the relay latching or non-latching menu and shows either r 1-L 
(for relay 1 latching), or r 1-N (for relay 1 non-latching). 
Use Up/Down to change the relay action. The diagram on page 47 shows the effect of
latching or non-latching relays.
8 Press OK to accept the change.
The display now changes to the current A2 Alarm 2 setting.
9Alarm 2 settings are changed in the same way as for Alarm 1. 
A2 alarm levels can be set between the A1 alarm level and the full scale range. The default
setting is 50% of the full scale range. 1 Access the menu system and select the   
menu option.
Press Up or Down. The icon flashes.
2 Press OK.
The current A1 (alarm 1) setting is displayed.
3 Use Up/Down to change the value.

If the gas units are %V/V and the gas being detected
is oxygen then a rising alarm UP or a falling alarm
DOWN, can be selected. Use Up/Down to change
the value.
5 Press OK to accept the change.
The display changes to the A1 relay action menu.
The display shows either r 1-d (for Relay 1 de-
energized), or r 1-E (for Relay 1 energized).

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.
Caution Calibration of the gas detector and the controller is mandatory 
during commissioning to ensure their proper functioning.
The controller with attached gas detectors should be commissioned in the following order:
• first set the general controller configuration, see page 45
• set up any gas detectors that require local commissioning, e.g. Sensepoint Pro — 
this has its own display and user interface
• set the configuration of the channels fitted to the controller, see page 51
• further commission the channels to match the types of gas detector attached to the 
controller following the procedures described in this chapter 
The chapter describes how to put the two versions of each channel module into service with the
following types of gas detectors:
• 3-wire mV bridge
• 2-wire 4-20 mA sink, see page 59
• 3-wire 4-20 mA source, see page 60
Note On the subsequent diagrams,   = LED ON,  = LED OFF
3-wire mV Bridge
This description covers connection to gas detectors such as Sensepoint
Flammable. Carry out the following procedure.
1 Check that all power and electrical connections to the 
controller, and electrical connections to the gas detector are 
correct.
For gas detector details see its user manual. For detector to
controller wiring details see page 21.
2 Apply power to the controller and check basic channel 
information is displayed.
See page 29. To skip the channel warm up sequence press and
hold the Cancel button on the Channel Module for 3 seconds.

10 Fit a flow adapter to the gas detector sensor.
First remove any accessory fitted to the sensor, e.g. weather protection.
11 Apply calibration (span) gas to the detector.
Adjust the gas flow rate to 0.3 l/min. 
Note Honeywell Analytics recommend the use of half full-scale gas for calibration 
purposes (contact a distributor for the supply of calibration gas). 
The controller now displays the actual gas measurement at the gas detector.  3 Check for a minimum voltage of 2.9 Vdc at the detector. 
If incorrect check for constant current supply of 200 mA +/-2 mA.
For detectors other than Sensepoint Flammable refer to their
operating instructions. 
4 Close the detector enclosure.
For gas detector details see its user manual. 
5 Press the Up/Down buttons on the controller simultaneously.
This enters configuration mode and the Set Gas Units and Range
menu icon is displayed and flashes.
6 Select the Calibration Menu icon 
Use the Up/Down buttons.
7 Press the OK button.
The top left of the display reads C0 indicating the set zero menu
mode. The display shows the current gas reading real zero value.
Ensure the sensor is in clean air.
8 When the gas reading is stable, adjust the reading to zero.
Use the Up/Down buttons. 
9 Press OK. 
The display shows a 10 second countdown.
When the countdown finishes the display shows GOOD if set zero
has succeeded. The display then changes to the set span menu
mode indicated by CS in the top left of the display.
If set zero fails the display shows FA I L and returns to the start of
the set zero mode.

2-Wire 4-20 mA Sink
This describes connection to gas detectors such as Sensepoint Toxic.
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 21.
3Follow step 2 on page 57.
4 Check for a minimum voltage of 16 Vdc at the gas detector. 
For detectors other than Sensepoint Toxic/Oxygen refer to their operating instructions.
5 Check that the Touchpoint 4 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. 12 When the gas reading is stable adjust the reading to 
the actual concentration of the calibration gas applied 
to the sensor.
Use the Up/Down buttons.
13 Press the OK button.
The display shows a 10 second countdown.
If the set span succeeds the display shows GOOD. 
If the set span fails the display shows FAIL and returns to the
beginning of the set span mode.
After successfully setting the span the display returns to the menu
selection mode.
14 Switch off the calibration test gas and remove the flow 
adapter from the detector.
15 Refit any accessory to the detector.
16 Return Touchpoint 4 to normal operation.
Press the Cancel button. Alternatively select a different menu
option.
