ALPHA OMEGA INSTRUMENTS CORP. USER MANUAL
1 Overview
1.1 Explanation Of Graphic Symbols
The information listed below is essential to the proper operation of the monitor. Please review the
following safety precautions prior to using the monitor. Cautionary notes are included throughout this
manual.
WARNING MESSAGE
THIS SYMBOL IS INTENDED TO ALERT THE USER ABOUT GENERAL WARNINGS
AND IMPORTANT OPERATING AND MAINTENANCE INSTRUCTIONS.
WARNING
HAZARDOUS VOLTAGE. CONTACT MAY CAUSE ELECTRIC SHOCK OR BURN.
TURN OFF & LOCK OUT SYSTEM BEFORE SERVICING.
THIS SYMBOL IS INTENDED TO ALERT THE USER TO POTENTIALLY
DANGEROUS SITUATIONS.
1.2 Instrument Description
The Series 1300 Oxygen Deficiency Monitor allows for the simultaneous monitoring of breathing air
oxygen using up to three (3) separate oxygen sensors. For monitoring of a single location, the Series
1300 supports either a “Local Sensor” (located within the main electronics enclosure) or a “Remote
Sensor” (located in a separate remote electronics enclosure). For monitoring of multiple locations, up
to two (2) “Remote Sensors” can be added to the “Local Sensor” for a total of three (3) monitoring
locations. The standard input power to the Series 1300 instrument is 88-264VAC, 47-63Hz (Hertz).
Available power options include 12VDC or 18-36VDC (24VDC) and must be specified at the time of
order placement.
The Series 1300 Oxygen Deficiency Monitor is housed in a NEMA 1 equivalent enclosure rated for
general purpose indoor use. Oxygen values for all sensors are displayed on a 4 line by 20 character
liquid crystal display (LCD) with a total height of 0.81" (20.8 mm). Various display modes are available
that allow for viewing all sensors simultaneously or having the sensor oxygen values cycle in a large
font display mode. The front panel includes a membrane panel with seven buttons that provide
access to the monitor's settings. The monitor is equipped with four alarm relays (see specifications)
which are user configurable and can be set for fail-safe operation. Also included, is a built-in audible
indication of an oxygen alarm condition.
The Series 1300 Oxygen Deficiency Monitor comes equipped with two direct current (DC) analog
outputs. The analog outputs can be independently configured for 0-20mA or 4-20mA. Both are
scalable over the operating range of the monitor. Using a terminating resistor on either of these
outputs will provide an analog voltage up to 5 volts full scale up to a maximum of 1,000 feet.
The Series 1300 Oxygen Deficiency Monitor comes equipped standard with a data-logger and a
serial interface commonly referred to as RS-232. The interface is compatible with EIA/TIA-232E.
Optional addresses from 1 to 32 may be assigned to each monitor for communicating with up to 32
instruments on the RS-2321 or RS-485 bus.
1
The built in standard RS-232 by definition does not allow for more than one instrument on the same physical wires. An
external RS-232 to RS-485 adapter or an “Ethernet Serial server” can be used to allow addressing multiple RS-232 units by
converting the RS-232 signals to an alternate bus.

PAGE 2 Series 1300 Oxygen Deficiency Monitor
ALPHA OMEGA INSTRUMENTS CORP. USER MANUAL
1.5 Description Of Optional Equipment
The Series 1300 Oxygen Deficiency Monitor incorporates a host of standard features. For certain
requirements, user's may desire to augment the capabilities of the monitor by ordering the monitor with one or
more available options described below.
1.5.1 Battery Backup P/N 13-BAT
The Battery Backup option provides backup power to the Series 1300 Oxygen Deficiency Monitor during a
temporary loss of main power. Please see section 8 Battery Backup for more information on this option.
1.5.2 RS-485 P/N 13-485
The factory installed RS-485 is an optional upgrade to the factory default of RS-232 and offers the ability to
extend the distance from 50 feet maximum up to 4,000 feet between the monitor and the host system. This
option also provides serial communications (both sending and receiving ) between several monitors up to a
maximum of 32 on one RS-485 three wire communications channel.
1.5.3 Replacement Oxygen Sensor P/N 13-SEN
This option consists of just the sensor (no enclosure or electronics). This option should be ordered in the event
that the sensor is damaged or needs replacement due to end of life.
1.5.4 Remote Mounted Sensor Enclosure P/N 13-RSEN
This option consists of a NEMA 1 (IP 30) remote sensor enclosure containing the oxygen sensor and
associated circuitry used to communicate with the read out electronics. The remote sensors may be added to
the Series 1300 Oxygen Deficiency Monitor in the field by the user. See section 3.3 Remote Oxygen Sensors.
1.5.5 Analog Output Isolation P/N 13-ISO
Installed at the factory, this option provides galvanic isolation of both analog outputs. This eliminates any
potential ground loops when connecting to earth grounded inputs or powering from DC where the power return
could create a ground loop with the output grounds or the input and output grounds are tied to chassis ground.
The isolation also allows for a higher maximum load resistance up to 1200 ohms (24V @ 20mA) as opposed to
the 12V maximum of 300 ohms (6V @ 20mA).
1.5.6 Calibration Fixture P/N 13-CFN
The optional calibration fixture is recommended for checking the calibration of the Series 1300 Oxygen
Deficiency Monitor. Ideally, the source of the calibration gas should be compressed air (clean, dry, and oil free).
Most industrial gas suppliers can provide the compressed air in small hand-held cylinders. The calibration
fixture is designed to easily install over the gas opening of the Series 1300 oxygen sensor making a tight seal.
The fixture is equipped with ¼ inch tube fittings to deliver the compressed air through a 1/4" OD plastic tube
(not supplied). The sample pressure to the fixture should never exceed 1.5 pounds per square inch (PSIG) at a
corresponding sample flow rate of between 0.2 to 1.0 standard cubic feet per hour (SCFH) or 0.1 to 0.5 liters
per minute (LPM).
1.5.7 12VDC Power P/N 13-12V
Allows for a user supplied regulated 12V as the main source of power to the instrument. Minimum power
requirement is 25.2 Watts.
1.5.8 24VDC Power (18 To 36V) P/N 13-24V
Allows for 18 to 36VDC (nominal 24VDC) as the main source of power to the instrument. Minimum power
requirement is 35 Watts.
1.5.9 Extended Logger P/N 13-LOG
Adds almost four times the logging capacity to the existing built in logger. This option is installed at
the factory. Consult factory.

3.3.1 Remote Oxygen Sensor Installation Procedure
Follow the procedure below for connecting the first Remote Oxygen Sensor.
CAUTION
REMOVE ANY POWER FROM THE INSTRUMENT BEFORE PERFORMING ANY
WIRING ON THE MAIN INSTRUMENT OR THE REMOTE OXYGEN SENSOR.
NOTE: For best results it is recommended to use a twisted shielded pair to connect to the Remote
Oxygen Sensors. Using #22 AWG (American Wiring Gauge) will allow distances up to 1000'. Longer
lengths available with larger diameter wire (consult factory). In most cases the proper cable is
specified at time of order and will be supplied by the factory.
Connecting Remote Oxygen Sensor #1 (refer to Table 2 - Remote Oxygen Sensor Connections
(Terminal Block 1) on page 14 above):
1. Connect the SHIELD wire of the twisted pair shielded cable to TB1, terminal 1 of the main
electronics. This wire should terminate at terminal block TB1, terminal 1 inside the Remote Oxygen
Sensor. Make sure all wires are put through the strain relief first.
2. Connect the POSITIVE wire of the twisted pair shielded cable to TB1, terminal 2 of the main
electronics. This wire should terminate at terminal block TB1, terminal 2 inside the Remote Oxygen
Sensor.
3. Connect the RETURN wire of the twisted pair shielded cable to TB1, terminal 3 of the main
electronics. This wire should terminate at terminal block TB1, terminal 3 inside the Remote Oxygen
Sensor.
Series 1300 Oxygen Deficiency Monitor PAGE 15
USER MANUAL ALPHA OMEGA INSTRUMENTS CORP.
Repeat the above procedure to connect the second Remote Oxygen Sensor if applicable but
substitute the terminals as follows:
1. Connect the SHIELD (TB1, terminal 4) of the main electronics to TB1, terminal 1 inside the 2
Remote Oxygen Sensor.
2. Connect the POSITIVE (TB1, terminal 5) of the main electronics to TB1, terminal 2 inside the 2
Remote Oxygen Sensor
3. Connect THE RETURN (TB1, terminal 6) of the main electronics to TB1, terminal 3 inside the 2
Remote Oxygen Sensor

After connection to the Remote Oxygen Sensor(s) has been completed, power the instrument and
wait for it to initialize. The display should now show each sensor being initialized. Please reference
section 6 “Sensor Setup” on page 47 for more information on setting up the sensor(s).
NOTE: Remote Oxygen Sensors do not need to be connected to the unit sequentially. They will be
detected based on the terminals they are connected to.
3.4 Horn And Strobe
The interface to the Horn and Strobes is located at terminal block TB1 (Refer to Figure 4) inside the
main enclosure. The Series 1300 Oxygen Deficiency Monitor is capable of supporting up to 8 horn and
strobes. The horn and strobes use a 3 wire connection3 consisting of power, ground return, and data.
The connections within the main electronics enclosure are located on a terminal block located in the
bottom of the enclosure labeled “TB1”. See Table 3 below for reference.

Table 3 - Horn And Strobe Connections (Terminal Block 1)
Follow the procedure below for connecting a horn and strobe that will be powered from the Series
1300 Oxygen Deficiency Monitor.
1. Connect the 1st wire of the shielded cable to TB1 terminal 9 (POSITIVE), inside the main enclosure.
Terminate this wire to one of the terminals on the horn and strobe PCB labeled “V+”.
2. Likewise connect the 2nd wire of the shielded cable to TB1 terminal 10 (DATA). Terminate this wire
to one of the terminals on the horn and strobe PCB labeled “DAT”.
3. Connect the 3rd wire of the shielded cable to TB1 terminal 11 (RETURN). Terminate this wire to one
of the terminals on the horn and strobe PCB labeled “GND“.
4. Connect the shield of the shielded cable to TB1 terminal 8 (SHIELD). Terminate this shield to one of
the terminals on the horn and strobe PCB labeled “SH”.
Note: it is only necessary to connect the shield at the horn and strobe PCB when daisy-chaining4. In a
star-point configuration, simply leave it disconnected.
3
Horn and Strobes can be wired directly to the relay contacts using only two (2) wires. The Series 1300 Oxygen Deficiency
Monitor will not be able to warn the user of any disconnect or wiring problem without the use of the “DAT” line.
PAGE 16 Series 1300 Oxygen Deficiency Monitor
ALPHA OMEGA INSTRUMENTS CORP. USER MANUAL
Follow the same procedure to connect multiple horn and strobe units to the Series 1300. The main
enclosure and the horn and strobe unit both have multiple terminals that can accept more than a
single wire twisted together if necessary. If daisy-chaining, then simply connect to the second set of
terminals supplied on the horn and strobe unit.
When powered from 90-264 VAC, 47-63 Hz., the instruments default DC output power is capable of
driving up to 4 horn and strobes simultaneously. If more than 4 are required, the additional horn and
strobes need to be powered from either an independent DC power source or an upgraded power
supply that can handle the extra horn and strobes. The maximum length of cable for a single horn
and strobe wired with the recommended #18 AWG wire can be up to 1,000 feet away from the main
electronics. However, each additional horn and strobe wired in SERIES (daisy-chained) on the SAME
wire will reduce the maximum length by approximately half. The maximum voltage drop in any single
chain of wire must be less than or equal to 3V. There must be a minimum of 9V at the end of the wire.
CAUTION
THE MAX CABLE CAPACITANCE OF 0.15UF MUST BE ADHERED TO OR THE
HORN AND STROBES MAY NOT WORK CORRECTLY AND/OR CAUSE
UNWANTED BEHAVIOR. PLEASE CONTACT THE FACTORY FOR ANY
APPLICATIONS REQUIRING LONGER LENGTHS.
Figure 12 below shows a horn and strobe and the associated printed circuit board (PCB).
Figure 12 - Horn And Strobe With PCB
3.4.1 Horn And Strobe PCB
The printed circuit board has 8 terminals located on the front edge as shown in Figure 13 - Horn and
Strobe PCB on page 17. The signals are labeled on the board as “DAT” for data, “V+” for positive
power, “GND” for power return, and “SH” for shield. Each signal has two connections to allow daisychaining. If daisy-chaining multiple horn and strobes, the connectors are sized to allow for twisting
two wires together before inserting into the screw terminal.

up to (4) more.
This requires
external Power
or a higher
rated internal
power supply.
CAUTION
J1 TO J4 SUPPORT A MAXIMUM OF FOUR (4) HORN AND STROBES UNLESS
USING A SPECIAL HIGH POWERED MAIN POWER SUPPLY. NEVER CONNECT
AN EXTERNAL POWER SUPPLY TO THE “V+” TERMINALS.
Note, that if powering the instrument from an external power supply, it is imperative that the power
supplied be sufficient for the number of horn and strobes connected at any given time. (5) or more
horn and strobes will require remote power or a higher wattage upgrade to the internal power supply.
The additional external power needed to handle up to four (4) standard horn and strobes is
approximately 20W. Therefore, using a 45W, 12V power supply would be able to power the Series
1300 Oxygen Deficiency Monitor as well as all eight (8) horn and strobes.
When externally powered, connect only the “DAT” and “GND” terminals back to the main electronics
enclosure. The “V+” terminal can be omitted in this case as it is not powered from the main
electronics. The external power supply connects to “EXT PWR” terminal located on the right hand
side labeled “J5”.
CAUTION
REMOVE POWER BEFORE PERFORMING ANY WIRING ON THE INSTRUMENT
OR HORN AND STROBE(S). IF EQUIPPED WITH BATTERY BACKUP, INSURE THE
BATTERY TERMINAL INSIDE THE MAIN ENCLOSURE IS DISCONNECTED.
3.4.2 Horn And Strobe Daisy Chain Configuration
This configuration shows how the wiring can be configured in a serial fashion or “daisy chain”. The
source wiring comes in on one set of connectors and the next horn and strobe is wired to the other
set of connectors as shown below.
