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 conguration. 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
conguration settings.
*All Honeywell Analytics gas detectors and third party detectors subject to overall power
requirements.

4.3 Maximum Cable Lengths
4.3.1 mA Detectors
To calculate the maximum cable run length from power source to the detector refer to the
following example diagram and formula.
Rloop = (Vcontroller - 1.5V - Vdetector min) / Idetector
Maximum cable run length = Rloop / cable per metre resistance where:
Rloop = maximum working cable loop resistance
Vcontroller = maximum available supply voltage at controller
Vdetector min = minimum voltage at which the connected sensor can operate
(sensor dependent, see individual sensor technical manual/
data sheets)
Idetector = sensor maximum drawn current. 30mA for 2 wire mA detectors.
See individual detector technical manual/data sheets for max power
consumption of 3 wire detectors.
4.3.2 mV Detectors
To calculate the maximum cable run length to the detector refer to the following typical
example cable resistances. Max cable loop resistance = 28 ohms.

6 Switch On
After connecting power, the controller enters a self test routine: All LCD segments ash, the
fault and alarm LED ash, the sounder operates three times, the RAM, ROM and EEPROM are
checked and the software version is displayed. If no faults are found (see section 7.5 for fault
codes) the unit enters a detector warm up period indicted by a count down from 60 to 0 on the
display. During this time the controller is inhibited (‘Inh’) so all alarms and faults are inactive.
At the end of the warm-up period the controller checks for detector and eld wiring faults. If a
fault is found, the fault code is displayed (see section 7.5 for fault codes). If no fault is found
the controller enters normal operation and will display current gas reading and alarm(s) if
appropriate.

8.5 Fault Codes
Below are the fault codes and recommended action to clear the fault.
8.6 Inhibit
The controller is put into inhibit via a normally open switch connected to the inhibit terminal or
when entering conguration mode. The inhibit is maintained until the switch is opened again or
on return to normal operation mode.
Additionally, an inhibit signal of between 1.5mA to 2.5mA can be signaled to the controller from
a eld device. This facility is only available on mA version controllers (see section 9).
When in inhibit the alarm relay and sounder do not operate. The alarm LED will operate if the
alarm threshold is exceeded. The 2nd line of the LCD will show Inh (except in conguration
mode where a slow ashing fault LED indicates the inhibit).
The controller can also be disabled using the disable function in the conguration mode (see
section 9).
See section 10 for details of how the relay delay and hold function is affected by inhibit.
8.7 Overrange
When the gas reading exceeds full scale ‘Or’ replaces the gas reading to indicate an overrange
condition. The 2nd line of the LCD continues to show the alarm state. If alarm level 3 is
congured latching then the overrange condition will also latch (default for 3 wire mV version).
8.8 Self Test
The controller enters a self test routine at power on. It can also be forced into a self test by
pressing the 3button in normal operation. The controller automatically conducts a self test at
regular intervals.

10 Ranges and Units
Below are the possible combinations of range and units for the two Unipoint Controller types:
11 Alarm Relay On/Off Delay
Part of the ‘Set Alarms’ conguration allows a user programmable delay for each alarm
threshold between the detection of an alarm and the activation of the alarm relay output, and
a programmable hold between the clearing of an alarm and the release of the relay output. The
delay times are adjustable over the range 0 to 900 seconds (900sec equals 15mins).
The default delay times are 0 (no delay).
WARNING
If an alarm relay activation delay is set to greater than 0 secs the
presence of a gas concentration in excess of the alarm threshold will
not be immediately signaled.
11.1 Alarm Relay On Delay
The programmable alarm relay delay operates in the following manner:
• If the delay is set, then in the event of the GAS CONCENTRATION EXCEEDING the alarm
threshold the following occurs:
• The LCD, LED, and buzzer signal the alarm.
• The alarm relay output does not signal the occurrence of the alarm immediately.
• The delay counts down.
• When the delay has expired, the relay output then signals the alarm.
• If during the delay the GAS CONCENTRATION FALLS below the alarm threshold and the
alarm is congured as NON-LATCHING, the indication of the alarm on the LCD, LED, and
buzzer is removed and the delay reset.
• If during the delay the gas CONCENTRATION FALLS below the alarm threshold and the
alarm is congured as LATCHING, the indication of the alarm on the LCD, LED, and buzzer
remains, the delay continues to run and the relay output is updated when the delay time
has expired.
• If during the delay the GAS CONCENTRATION IS ABOVE the alarm threshold and the
ACCEPT/RESET INPUT/KEY is activated to accept the alarm, the LCD, LED, and buzzer
will respond as per section 7.4, the delay continues to run and the relay output is updated
when the delay time has expired.
• If during the delay the GAS CONCENTRATION FALLS BELOW the alarm threshold, the alarm
is congured as LATCHING, and the ACCEPT/RESET EXTERNAL INPUT/KEY is activated to
reset the alarm, the LCD, LED, buzzer and the delay time reset.

• If during the delay the unit is placed into INHIBIT by either the external inhibit or by entering
the conguration mode, the delay will be reset. On exiting the inhibit mode the relay output
will be updated.
• If during the delay a FAULT is signaled, the delay will continue and the relay output updated
when the delay time has expired. (The alarm will continue to be signaled on the sounder,
LED, and LCD after the fault occurs. The relay output will be updated to reect the alarm
when the time expires.)
11.2 Alarm Relay Off Delay
The programmable alarm relay hold operates in the following manner.
• If the hold time is set, then in the event of the GAS CONCENTRATION FALLING below the
alarm threshold after previously exceeding the alarm threshold for a period of time greater
than the delay time (i.e. the relay output is reecting the active alarm) and the alarm
threshold is congured as NON-LATCHING the following occurs:
• The LCD, LED, and buzzer will stop signaling the alarm.
• The alarm relay does not signal the absence of the alarm immediately.
• The hold time counts down.
• When the hold time expires, the relay output is updated to signal the absence of
the alarm.
• If during the hold time the gas CONCENTRATION RISES back above the alarm threshold,
the LCD, LED, and buzzer signal the re-occurrence of the alarm and the hold time is reset.
• If during the hold time the ACCEPT/RESET EXTERNAL INPUT/KEY is activated, the relay
output is updated immediately.
• If during the hold time the unit is placed into INHIBIT by either the external inhibit or by
entering the conguration mode, the hold time is reset. On exiting the inhibit mode the relay
output is updated immediately.
• If during the hold time a FAULT is signaled, the hold time is reset and the relay output
is updated immediately.
• If the alarm is congured as LATCHING, the hold time has no effect upon the operation of
the unit. i.e. The signaling of a latched alarm via the relay output will removed immediately
the accept/reset external input/key is activated.
12 Maintenance
The Unipoint controller has no user serviceable parts. Honeywell Analytics recommend that the
controller’s conguration and operation are checked annually.
The gas detectors connected to the controller should be checked and if necessary zero and
span calibrated by following the procedures detailed in their user guides.
