Zareba Unipoint controller

The Zareba Unipoint,
a simple DIN rail
mounted controller

Unipoint DIN controller

Typical Applications

• Small and medium integrated systems

• Custom control cabinets and panels

• Unmanned equipment rooms

• Boiler Houses

• HVAC systems

• Analyzer houses

• Car Parks

• Crane cabs

• Laboratories

User Friendly

• Ultra-clear backlit display

• System status codes

• Built-in audiovisual alarms

• Intuitive menu system

• Simple pushbutton operation

• Remote accept, reset and inhibit inputs

Easy to Install

• TS35 (‘top hat’) DIN rail mounting

• Removable terminal connectors.

• DC operation

• 3 x alarm relays

• 1 x system fault relay

• Field inhibit input (mA versions)

Flexible Operation

• Fully user programmable scale, units

and calibration

• Relays configurable as energized, de-energized,
latching or non-latching, alarm relay on/off delay

• Compatible with a wide range of gas detectors

The Zareba Unipoint is a simple
DIN rail mounted controller offering
integrators a flexible and low cost solution
to incorporate flammable, toxic or oxygen
gas detection into their control systems.

Unipoint can be easily installed into any plastic
or metal enclosure for use indoor or outdoors
and even in potentially explosive atmospheres.
With the addition of one of the Zareba range of
flammable, toxic or oxygen detectors, systems
may be configured to monitor gases in a wide
range of applications from car parks and boiler
houses to analyzer shelters or crane cabs in
offshore facilities.

Two versions of Unipoint are available; one
for mV bridge, catalytic bead type, flammable
gas detector and the other for any 2 or 3 wire
4-20mA type gas detector. Each Unipoint is
easily installed onto the DIN rail via a special
socket (provided) that also interconnects power
to adjacent units. With removable terminal
connectors individual Unipoint controllers can be
easily changed without disturbing other devices.

By clipping together multiple Unipoints small
to medium sized monitoring solutions can be
realized. Each unit includes built-in audiovisual
alarms, three programmable alarm relays and
a fault relay. Gas concentration and system
status is displayed on the backlit LCD and each
controller is fully user programmable via an
intuitive, push button operated menu system.
Configuration menus can be password protected
to prevent unauthorized access. In addition
remote inputs allow accept, reset and inhibit of
alarms without the need to open the enclosure
that the Unipoint is mounted in.

Unipoint’s uncomplicated design makes it
ideal for applications where a simple method
of integrating gas detectors into a 3rd party
control system is required or as part of a small
standalone gas detection solution. All Honeywell
Analytics gas detectors and third party detectors
may be used with Unipoint subject to overall
power requirements.

many applications requiring flammable, toxic or oxygen gas detection to be incorporated into
their control systems. Unipoint is designed to use industry standard DIN rail allowing it to be
easily installed into many different types of plastic or metal, indoor or outdoor, hazardous or non
hazardous area enclosures. It is designed for use with any mV flammable gas detector as well

as any 2 or 3 wire 4-20mA gas detector (subject to overall power requirements).
