							   Introduction
TP1MAN Issue 4_03-10 (MAN0630)7
Touchpoint 1 is a self-contained single channel gas detector controller for use in indoor safe
areas. It is designed for use with the Honeywell Analytics range of Flammable, Toxic and Oxygen
gas detectors — Sensepoint, Sensepoint Plus and Sensepoint Pro. Other types of detector may
also be connected to the unit after verification of power requirements.
Two types of controller are available:
• mV version — for 3-wire mV flammable gas detectors, e.g. Sensepoint Flammable 
detector
• 4-20 mA version — for 2 and 3-wire 4-20 mA gas detectors, e.g. Sensepoint Toxic and 
oxygen detectors, Sensepoint Plus and Sensepoint Pro detectors
Touchpoint 1 is wall mounted and displays gas concentration, alarm, fault and status
information via a backlit LCD and LEDs, together with a built in audible alarm. A keypad, located
beneath a panel under the display, allows user interaction with the unit.
The controller is AC and/or DC powered. A gas detector is connected to the controller via a
terminal module that also provide connections for relay and repeated 4-20 mA signals.

Enclosure
The rigid steel enclosure houses the Display Module and Terminal Module, and has integral
mounting hooks on the rear for fitting to a supplied mounting plate.
The base of the box has 3 cable/conduit knock-out entries to enable wiring to the Terminal
Module. A hinged door below the Display Module provides access to the Terminal Module. it
may be latched open for hands-free access. For mechanical installation details see page 9.
Display Module
One of the following two types of Display Module is fitted to the controller:
•  mV module
• 4-20 mA module
The module allows easy set-up and configuration/calibration of the channel and attached gas
detector.
It features an LCD screen, to display gas concentrations and ranges, settings, time, alarms and
faults, and 4 buttons, three behind a Controls Access Door, that are used to navigate through
an integral menu system to set-up the controller/detector settings and view an event record of
controller status, e.g. alarms, etc.
Terminal Module
This module provides the connection point for power and signals, and features the following:
• 16-wire terminal block for the gas detector signals, relay outputs, repeated 
4-20 mA signal and battery supply/backup power
•  3-wire terminal block for AC power
•  power on/off toggle switch and replaceable fuse
• 3 relays for alarms and faults
For electrical installation details see page 13.
General

WARNINGS
Touchpoint 1 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, or obtain a hot work permit, 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. 
Caution When carrying out any work ensure that executive outputs from the 
controller are inhibited in order to prevent false alarms.
This chapter provides the following information about installing Touchpoint 1:
• where to locate the controller, its dimensions and how to mount it
• how to access the interior of the controller, see page 12
• cabling and wiring, see page 13 and page 14
Note It is recommended that a local fused power feed spur, with lockout switch, is used.
Earth/Ground loops or poor screening are the most common cause of false alarms. 
Proper installation, using appropriate earth techniques improves:
• resistance to radio frequency interference (RFI), e.g. mobile phones and walkie-talkies
• resistance to induced signals from magnetic fields (EMC), e.g. high power cables 
and switch gear.
Location
Touchpoint 1 can only be installed in indoor safe areas. 
Refer to International codes of practice, e.g. National Electrical Code (NEC) or Canadian
Electrical Code (CEC), where applicable, for guidance when installing.
Ensure that the maximum distance from the controller to the detector is within specification.
Locate the bracket so that when the controller is fitted to it there is:
• easy access to it
• a clear view of the controller‘s display (normally eye level), check for national/
local regulations regarding the viewing of displays

• enough space to open the enclosure’s access panels, for cabling, maintenance, 
adjustments, etc.
• enough space for cable or conduit access to the bottom of the enclosure
Follow the advice of:
• experts having specialist knowledge of gas detection and control systems 
• experts having knowledge of the process plant system and equipment involved
• safety and engineering personnel
Always record the location of the detector that is connected to the controller.
