Page 3: System Overview
The TOM-2B features a zirconium oxide O2 sensor with a life span of 10 years of continuous operation. Sensor behavior is very stable under nominally changing environmental conditions of temperature, pressure, and humidity. -
Page 4: System Specifications
Physical Dimensions 8” (W) x 12” (H) x 6” (D) (Control Unit) Weight 10.0 pounds (4.5 kg) including solenoid valve and transducers Enclosure Type NEMA 1,2,4,4X rated, polycarbonate, indoor/outdoor use Revision D, Copyright ©2022, EMS Healthcare LLC, all rights reserved... -
Page 5: System Installation
5-meter hardwired cable for installation into the facility vacuum system. The TOM-2B enclosure should be mounted vertically on or near the vacuum pump skid to allow installation of the sensors and valve into the facility vacuum system as indicated in the diagram below. -
Page 6: Facility Wiring
Green/Yellow Ground Terminal 2. Solenoid Valve Wiring – The TOM-2B comes with a type-LB conduit body and wire nuts for completing wiring terminations at the solenoid valve electrical interface. The solenoid valve operates with 24VDC so the RED (V+) and BLACK (V-) wires from the TOM-2B unit should be connected to the RED wires at the solenoid. -
Page 7: Mitigating Gas
Therefore, it is suggested that these facilities use carbon dioxide or nitrogen as a mitigating gas to more rapidly respond to increasing oxygen levels detected by the TOM-2B. See the Specifications page for gas connection sizing and acceptable pressure input levels if carbon dioxide or nitrogen gas will be used. - Page 8 (MITIGATE mode only) ALARM (red) = O2 level has SYS HEALTH exceeded alarm limit NO FAULTS (green) = healthy FAULT (red) = system has detected one or more faults Revision D, Copyright ©2022, EMS Healthcare LLC, all rights reserved...

Page 9: System Operation
System Operation System Configuration The TOM-2B provides a touch screen display interface that allows the user to monitor system operations and adjust configuration settings as needed. The MAIN screen (as shown above) allows access to Settings, Calibrations, real-time data trending, system statistics, and system faults by pressing MENU on the display. - Page 10 If this situation occurs, the facility should develop a procedure to physically monitor the vacuum system pumps, inspect the O2% reading on the TOM-2B and, if the reading is below the O2 alarm limit of 23.6%, reset the O2 alarm. Then...
- Page 11 In MONITOR ONLY MODE, the system continuously monitors oxygen levels and provides O2 alarm indications. In this mode, only the O2 sensor input is required. Revision D, Copyright ©2022, EMS Healthcare LLC, all rights reserved...

TOM-2 Operators Manual System Maintenance Annual Compliance Reporting EMS Healthcare recommends downloading the time history log from the thumb drive on an annual basis to provide the facility a report of oxygen concentration compliance to the NFPA 99 requirement. Periodic Sensor Check EMS Healthcare recommends checking the O2 sensor on an annual basis to verify sensor accuracy.
