Product Overview
The Otis Instruments, Inc. GenII WireFree OI-6940 Notis Quad is a battery- owered ex losion- roof 4-gas sensor
assembly that simultaneously uses u to four sensors—Electrochemical or Low-Power Infrared—for sensing an array of
toxic gases in ambient air.
The Notis Quad comes standard with a 160x104 ixel gra hical LCD screen, four-button interface, non-intrusive
magnetic switches, and one radio (900MHz or 2.4GHz).
Like other Otis Instruments sensor assemblies, the Notis Quad features non-intrusive calibration and configuration. With
all adjustments made at the sensor assembly, one-man non-intrusive calibration is quick, easy, and allows the sensor
housing and enclosure to remain Class I, Division 1, Grou C and D certified while in the field. Non-intrusive calibration
is made ossible by using an Otis Instruments, Inc. distributed magnet to activate the MENU, BACK, ADD, and SUB
buttons.
The Notis Quad is designed to be self-contained and to last for u to 6 months using a 3.6V 76 Am Hour battery- ack.
The Notis Quad is field adjustable for background gas, and addressable to eliminate interference with other systems. The
device has been designed to reject EMI and other forms of interference in order to avoid false gas readings.

Introduction
This document is an O eration Manual containing diagrams and ste -by-ste instruction for ro er o eration of the Otis
Instruments, Inc. WireFree Model OI-6940 Notis Quad 4-Gas Sensor Assembly. This document should be read before
initial o eration of the roduct.
Should a question arise during the use of the roduct, this document will serve as a first reference for consultation. If
further questions arise, or if the device is not working ro erly, lease contact the sales re resentative of this roduct.

Warnings
Do not o en the enclosure when the device is energized.
Do not o en the enclosure if an ex losive gas atmos here may be resent.
The Otis Instruments WireFree OI-6940 Notis Quad 4-Gas Sensor Assembly is Class I Division I, Grou s
C&D Certified. The assembly is able to maintain its certification at all times while in the field, sim ly by using
the non-intrusive calibration method which requires the use of an Otis Instruments, Inc. distributed magnet.
However, if the enclosure lid is removed, for whatever reason, the OI-6940 Notis Quad certification is not
valid. To avoid invalidating the certification, once the device is ut in the field, always use the Otis
Instruments, Inc. distributed magnet to ensure non-intrusive calibration.
Strong magnetic fields may interfere with the non-intrusive magnetic switches. A strong magnetic field may
momentarily active a switch, or ermanently disable the switch to the “on” or “off” osition.
Do not cover the hole in the calibration cu , as this will cause the calibration to be inaccurate.

Button Functions
When navigating through the Global Settings Menu Mode or Sensor Settings Menu Mode: touch ADD to advance to the
next screen; touch SUB to return to the revious screen; touch MENU to select the dis layed o tion (or, in cases when
“BACK” is dis layed on the to left side of the Dis lay Screen, to return to the revious o tion); and touch BACK to
return to the revious o tion. For an illustration of the button functions with on-screen labels dis layed, see the Button
Functions Diagram at the beginning of this O eration Manual.

Radio Transmission Information
●When the radio sends, it sends all sensors—starting with sensor 1—unless in Relay Test Mode. When in Relay
Test Mode: the radio only sends the sensor that is in Relay Test Mode; the radio only sends when ADD or SUB are
touched.
●When sending a radio transmission in any mode other than Normal O erating Mode, the sensor that is currently
being viewed will send what mode it is in, while the other sensors will send that they are in the Advanced Menu
Mode. If none of the sensors are in a mode, all sensors will send that they are in the Advanced Menu Mode.
●When in Normal O erating Mode, the radio sends a transmission once er minute (a rox.)—when no sensor is
seeing gas. When at least one sensor is seeing gas, the radio sends a transmission once every 5 seconds (a rox.).
Regardless of how many sensor are seeing gas, the radio will send transmissions for all sensors at one of the
reviously listed time intervals—based on if one or no sensors are seeing gas.
●When in Cal Mode or Null Mode, the radio will transmit once every 8 seconds (a rox.).
●If the Notis Quad is in any mode other than Relay Test Mode the radio will transmit every 13 seconds (a rox.).
13 seconds is from the last time MENU was touched—or the last time the radio transmitted—de ending on which
one ha ened last.

Power On (from Power Off ode)
Powering on the device activates its functions. When owered on, the device is fully functional and access to system and
settings menus is allowed.
1. Touch an Otis Instruments, Inc. distributed magnet to the ADD indicator label on the left side of the Notis Quad to
activate ADD (and turn on the device).
