1. SCOPE.

1.1 Identification.

This specification encompasses the user and performance requirements for the Next Generation

Chemical Detector 1 (NGCD 1) Aerosol and Vapor Chemical Agent Detector (AVCAD) system.

The AVCAD system consists of the Detector and the Remote Alarm, and specifications apply to both components unless otherwise noted. The AVCAD system, hereafter referred to as AVCAD, will detect, identify, alarm, and report the presence of aerosol and vapor chemical hazards. This specification defines the development of a Technology Readiness Level (TRL) 8 production system as shown in Table 1.

Table 1. AVCAD Technology Readiness Levels

TRL Definition Description Supporting Information

4 Breadboard Basic technological components are integrated and have been established to work together. The technologies are understood and well documented, draft component interface control documents (ICDs) are available, and the algorithm software approach and programming environment is defined.

Low-fidelity laboratory system that is not required to be packaged. The system is capable of being tested in a chemical fume hood and collecting chemical spectral information relevant to the technological approach. Limited chemical warfare agent (CWA), Non-Traditional Agent

(NTA), and simulant testing. The detector has rudimentary, autonomous algorithms and spectral information is available to assist algorithm development. System components are not production representative.

5 Brassboard Basic technological components are integrated with realistic supporting elements such that chemical testing in simulated environments can occur.

Draft ICD and draft component configuration management (CM) documentation is available.

High-fidelity laboratory detection system that is packaged, but packaging is not required to be in its final form factor. The detector has an on-board, autonomous algorithm that is capable of alarming to or “flagging” target chemicals.

Testing of the chemicals identified in the

Performance Specification has demonstrated the capability to detect NTAs and CWAs. Limited user interfaces (screen, keypad, alarms, etc.) are present in the system.

6 Prototype Representative prototype system that is capable of being tested in a high-fidelity laboratory environment or in a simulated operational environment.

The system ICD, CM documentation, and draft Technical Manuals are available.

Prototype detector that is packaged in the final detector form factor including all modular components. Detector enclosure materials may not be the final materials and internal component anchors may not withstand military employment.

The system is capable of being tested in a chemical fume hood and collecting chemical spectral information relevant to the technological approach. The detector has an onboard, autonomous algorithm that provides alarms to local users when tested with target chemical species under simulated environmental conditions. The system may not pass induced environmental testing in accordance with (IAW)

Military Standard 810 (MIL-STD-810).

1.2 System Threat Overview.

The AVCAD will face physical destruction threats equivalent to those of the site or asset it is intended to support. Use of agent dissemination enhancements and battlefield obscurants may degrade the system’s ability to detect and identify chemical threats. The system will be vulnerable to exposure and the material degrading effects of chemical threats and their respective means of decontamination. Although not a primary target, the system can receive collateral damage from a broad range of threat weapon systems, including aerial attack, ground maneuver forces, missile, artillery, special operations forces, terrorist activity, and information warfare and electronic warfare

(EW) systems such as Radio Frequency Weapons. Additionally, it may be digitally subject to intrusion jamming and interruption. The system may be subjected to the effects of electromagnetic interference (EMI) and electromagnetic effects from nuclear, advanced technology, and EW weapons, as well as power interruptions.

1.3 Mission Description and Operational Concept.

The AVCAD Mission Descriptions and Operational Concepts are in Appendix A for reference.

Table 5. AVCAD States and Modes

States and Modes Description

Off State In the Off State, the AVCAD shall be carried, emplaced, or mounted in the position from which it will operate. The AVCAD electronics shall be unpowered, and the system shall require action by the operator to proceed into another state. The AVCAD may be connected to a power supply (shore power or battery), but the system is still safe to maintain.

Power-Up State From the Off State, the AVCAD shall enter into the Power-Up State when activated.

The Power-Up State is composed of two modes: Warm-up and BIT. These modes may occur concurrently or sequentially. If all system components pass during BIT

Mode, the AVCAD shall progress into the Normal Operation Mode of On State. If any system components fail, the AVCAD shall progress into the Degraded Operation

Mode of On State. The Power-Up State will continue until the system is ready to enter the On State.

Warm-Up Mode In Warm-Up Mode, the AVCAD shall initialize components (for example, heaters, pumps, etc.) required for On State functions.

Built-In-Test (BIT)

Mode

The system shall automatically perform BIT functions and, at completion, each system component shall return a signal to the operator indicating whether the components have passed or failed.

On State The On State is composed of up to eight modes: Normal Operation, Operator Selected

(Optional), Degraded Operation, Configuration, Confidence Check, Maintenance, Training, and Defunct. BIT functions shall continuously monitor system status and the system shall notify the operator of any failures.

Normal Operation

Mode (Default Mode)

In Normal Operation Mode, AVCAD shall automatically start sampling for chemical threat aerosols and vapors at the Rapid Response Concentrations (30-sec response time, if no Operator Selected Mode) and shall detect all chemicals required in this specification. When a chemical threat is detected, the AVCAD shall perform the necessary functions (for example, detect, identify, alarm to, and report on any chemical threats that are detected) to complete the mission. If a detector does not have modes of operation, AVCAD shall automatically start sampling for threat aerosols and vapors at both the Rapid Response and Post-Event Monitoring Concentrations. If any system components fail BIT during Normal Operation Mode, the system shall notify the operator of those failures, log the failures, and automatically progress into Degraded

Operation Mode. Event and failure logs shall be accessible while the detector is in

Normal Operation Mode, including while the system is sampling and recording data.

Operator Selected

Mode (Optional)

In Operator Selected Mode, AVCAD chemical sensitivity is selected to be either

Rapid Response Concentration (30-sec response time) or Post-Event Monitoring

Concentration (180-sec response time). Additional operator configurable settings, such as single chemical detection, may also be instituted in this mode. When a chemical threat is detected, the AVCAD shall perform the necessary functions to complete the mission. If any system components fail BIT during Operator Selected

States and Modes Description

Mode, the system shall notify the operator of those failures, log the failures, and automatically progress into Degraded Operation Mode. Event and failure logs shall be accessible while the detector is in Operator Selected Mode.

Degraded Operation

Mode

In Degraded Operation Mode, one or more of the AVCAD system components has failed and the detector is operating to the maximum extent possible with the functioning components. The system shall continue to alert the operator to all failures, including new failures, until they are corrected. Event and failure logs shall be accessible while the detector is in Degraded Operation Mode. Once all failures are corrected, the system shall automatically progress into to Normal Operation Mode.

Configuration Mode In Configuration Mode, the operator may configure the AVCAD for the desired level of operational functionality, which may include modification of communication settings, human interface settings, and audio and visual alarm settings.. The system shall have a pre-populated selection of sensor settings for the operator to choose.

Confidence Check

Mode

To perform a confidence check on the AVCAD, the operator enters the system into

Confidence Check Mode. After the confidence check process is complete, the system shall automatically progress into Normal Operation Mode.

Maintenance Mode In Maintenance Mode, the AVCAD shall allow for the performance of maintenance actions, including the upload of software upgrades, the download of stored data, and calibration activities. Event and failure logs shall be accessible while the detector is in

Maintenance Mode.

Training Mode In Training Mode, AVCAD shall function exactly the same as Normal Operation

Mode with the addition of any simulants that cause the system to alarm. The AVCAD is placed into training mode by the operator and shall display “Training Mode” on the display screen and in any messages communicate via the network. When a target chemical (CWA, NTA, TIC, or simulant) is encountered, the AVCAD shall perform the same functions as the Normal Operation Mode to complete the mission. If any system components fail BIT during Training Mode, the system shall notify the operator of those failures, log the failures, and stay in Training Mode. Event and failure logs shall be accessible while the detector is in Training Mode.

Defunct Mode An authorized command by the operator, network, or Remote Alarm shall place the

AVCAD into a Defunct Mode. This mode requires implementation of an operator key or mechanical function to avoid accidental trigger. In this mode, the system shall permanently erase (zeroize) all of the on-board software (spectral files, operating parameters, data files, etc.). The system shall require the upload of new software to become capable of performing Power-Up and On State functions.

Power-Down State From On State, after the operator places the system into Power-Down State, the

AVCAD shall initiate the process to progress into Off State. During Power-Down

State, the system will be incapable of performing any of the On State functions. The system shall automatically progress into Off State when the Power-Down process is complete.

Transport State In Transport State, the AVCAD shall be powered “off” with battery and required accessories installed. The AVCAD shall be in its transport case.

Storage State In Storage State, the AVCAD shall be powered “off” with batteries removed and with all external connections (physical mountings, electrical cables, and data cables) removed or detached. Storage procedures (special wrapping, desiccants, etc.) may be used to preserve the AVCAD.
