1 Safety
Ensure that this manual is read and understood BEFORE installing / operating / maintaining the
equipment.
WARNINGS
Unipoint 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.
Unipoint should be installed inside a lockable enclosure or in a
secure location to prevent unauthorized access.
Before carrying out any work ensure local regulations and site
procedures are followed. Work must only be conducted by trained
personnel. 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.
The fault and alarm relay outputs may be used to switch voltages
in excess of 50Vac. Ensure circuits have DOUBLE or REINFORCED
insulation and are segregated in accordance with the voltage being
switched and access is restricted to authorized personnel only.
Unipoint must be zero and span calibrated with the
detector before operation.
Disposal should be according to local waste management
requirements and environmental legislation. Alternatively contact
your local Honeywell Analytics representative.
Honeywell Analytics can take no responsibility for installation and/or use of its equipment if
this is not done in accordance with the appropriate issue and/or amendment of the manual.
The reader of this manual should ensure that it is appropriate in all details for the exact
equipment to be installed and/or operated. If in doubt, contact Honeywell Analytics for advice.

3 Introduction
Unipoint is a self-contained single channel gas detection controller for use in indoor safe areas.
It is designed for use with any mV ammable gas detector as well as any 2 wire or 3 wire
4-20mA source gas detector*. Unipoint is DIN rail mounted and displays gas concentration,
alarm, fault and status information via its backlit LCD and LEDs, as well as providing a built
in audible alarm. A keypad located below the display provides the facility to make changes
to the system conguration. Unipoint is powered from 24VDC via the DIN rail. The detectors
are connected to the controller via terminals on the side of the controller where terminals for
remote inhibit/reset and output relays are also located.
There are two versions of Unipoint controller available. The mV version is for use with 3 wire
mV ammable gas detectors such as the Signalpoint or Sensepoint range of ammable
detectors. The 4-20mA version is for use with 2 wire and 3 wire 4-20mA source detectors such
as the Signalpoint or Sensepoint range of toxic and oxygen detectors. It has 4 buttons: ‘s’
up, ‘t’ down, ‘x’ reset and ‘3’ OK, that are used navigate through the menus and change the
conguration settings.
*All Honeywell Analytics gas detectors and third party detectors subject to overall power
requirements.
4 Installation
WARNING
Unipoint is designed for installation and use in indoor safe area
non-explosive atmospheres. Installation must be in accordance
with the recognised standards of the appropriate authority in the
country concerned. Prior to carrying out any installation ensure local
regulations and site procedures are followed. The detectors used with
Unipoint are often designed for use in hazardous atmospheres. Refer
to the individual detector instructions for details of their installation.

UNIPOINT OPERATING MANUAL 2306M5001 MAN0638 ISSUE 7 01/2011
The Unipoint controller is mounted on standard symmetrical ‘top hat’ DIN Rail (35 x 7.5mm).
To attach the Unipoint controller to the DIN rail follow the procedure below use the Installation
Diagram as reference.
1. Clip the Unipoint controller socket on to the DIN rail (note the correct orientation from the
diagram below).
2. Clip the power connector on to the DIN rail beside the controller socket.
3. Slide the connector and socket together until clip engages.
4. Attach the Unipoint Controller on to the socket by gently but rmly pushing it down onto the
socket until it clips in place.
5. Additional Unipoint Controllers can be added to the DIN rail on the right hand side of the rst
unit. Clip additional controller sockets to rail and slide together until clips engage. Then attach
the additional Unipoint Controllers.
Note: If mounting the Unipoint controller(s) inside an enclosure, ensure that the temperature inside
the enclosure does not exceed the specified operating temperature.

4.2.3 Terminal Detail
All electrical connections except power are made via removable terminals located on the top
and bottom of the controller. The power connection is made via the power connector attached
to the DIN rail.
For security we recommend the use of Key Switches for the remote reset and inhibit inputs
mounted on the front of the enclosure in which the Unipoint is mounted.
4.2.4 Detector Types
Unipoint can accept signals from three types of detector. The table below summarizes the
types of detector compatible with Unipoint.
Type of detector Output to detector Recommended detector
2 wire 4-20mA Controller Input (18-32Vdc)-1.5*Vdc,
30mA (max). Sense resistor 33 Ohms.

4.2.5 Generic Detector Wiring Schematics
To connect the detector to the Unipoint use a 2 or 3 wire cable (as appropriate) that is suitably
armoured (e.g. Steel Wire Armour) or conduit according to local requirements. Acceptable wire
cross sectional area is from 0.5 to 1.5mm2 with overall screen. Connect the screen to ground at
the enclosure that the Unipoint is mounted in.
