Page 14: Overview
In addition, there are many specialized uses of the BRT6000, such as controlling the opening and closing valves in underwater and emergency recovery systems. The BRT6000 is made of Nickel Aluminum Bronze, making it rugged and durable enough for the harshest marine environments. -
Page 15: Basic Functionality
The Release commands will cause the BRT6000 to apply a voltage to the appropriate burn wire output pins on the bulkhead connector. The release commands can be sent and will cause a release whether the system is enabled or disabled. The enable and disable function only controls the transponder section. -

Page 21: Installation
3.1 Acoustic Considerations Efforts should be made to ensure a clear acoustic path between the BRT6000 NAB Transducer and the source (typically a dunking transducer attached to a deck unit). The top causes of signal degradation include syntactic foam, plastic floats, and floatation, including glass spheres. -
Page 22: Commands
COMMANDS When the appropriate command is decoded, the system will apply the power from the battery stack to the correct pin for that command. Release command 1 applies voltage to pin 2 of the end cap connector. Release command 2 applies voltage to pin 3 of the end cap connector. Pin 1 of the end cap connector is ground. -
Page 23: Operating Instructions
BRT6000 Burn Wire Release Transponder. 5.1 First Use The battery must be connected to start using the BRT6000 NAB. EdgeTech ships releases with batteries disconnected to prevent an unnecessary drain on battery life. To connect the battery, the release housing must be opened, the battery plugged in, and then release reassembled and purged. -
Page 24: Removing The Transducer End
5.1.2 Removing the Transducer End The transducer end of the release will have an integrated transducer or the connector for a separate cable connected transducer, depending on the configuration purchased. To remove the transducer end cap: 1. Disconnect the transducer cable from the release end cap if using a release with a separate transducer. -

If misaligned, damage to the electronics may occur, rendering the Board JP5 Release unusable until repaired. Connector The BRT6000 Burn Wire Release will ping once after it has powered up, and the transponder will be enabled. Battery Cable Connector Figure 5-5 Connecting the NAB-6000BRT Battery... -
Page 26: Closing The Transducer End
5.1.4 Closing the Transducer End Before closing the Transducer End, inspect the O-rings and O-ring mating surfaces and service if needed. To close the Release End: 1. Gently guide the transducer end cap back into the housing, taking care not to damage the sealing surface of the Housing or pinch any cables, as shown 5-6. -

Configuration card shipped with the unit. If the commands are not being received, verify the unit serial number matches what’s on the configuration sheet to ensure you’re configured to the correct unit. 1. Using the Deck Unit, ascertain whether the BRT6000 NAB is enabled or disabled by interrogating. -
Page 28: Voltage Output Testing
If the Unit has just been turned on, it will be enabled. b. Unless otherwise specified, the BRT6000 NAB will be shipped from EdgeTech, with the interrogate frequency tuned to 11 kHz and the reply frequency set to 12 kHz. -
Page 29: Leak Detection And Condensation Prevention
Figure 5-7: Assy Sub Cable BART End Cap VSG-3F Burn Wire Drawing (PN 0023018) 5.3 Leak Detection and Condensation Prevention EdgeTech’s releases have a 5/16-inch diameter purging port on the bottom connector end cap. This allows for the instrument's atmosphere to be purged for deployment. The recommended procedure for preparation of the instrument's atmosphere is as follows. -
Page 30: Post Deployment
• If the BRT6000 NAB is being shipped or stored, it should be disabled to conserve battery life. Likewise, if the BRT6000 NAB is not used again soon, the Unit should be turned off and the battery unplugged. If the Unit is to be stored for an extended period of time, the batteries should be removed. -
Page 31: Maintenance
6-11 MAINTENANCE The BRT6000 NAB requires minimal maintenance, including pre-deployment preparations, checks, and post-deployment cleaning. Critical tasks include battery replacement, O-ring care and maintenance, and general cleaning, inspection, and lubrication of operational elements.

Inspect for scratches or nicks which will impair the O-ring efficiency. Apply a Very light coat of O-ring lubricant (EdgeTech recommends using Parker Super O-lube) to the piston O-ring surface to aid sliding insertion of the piston seal. Inspect the O-rings for damage or manufacturing flaws such as tears, dimples, or inclusions in the rubber. - Page 34 6-14 2. Slip the electronics into the housing. Connect the transducer cable and the battery after the electronics are in the housing and before the transducer end cap is inserted. CAUTION! Do not pinch or damage wires when inserting the assembly into the housing.
