Product Overview

MSA NightFighter Heads-Up Display system comprising the transmitter module (P/N 10036995, Model 7-1219-1) and the HUD receiver module (P/N 10037792). The transmitter mounts to the SCBA shoulder gauge pressure hose; the receiver mounts to the MSA Ultra Elite Facepiece bracket and presents LED indicators in the lower right quadrant of the wearer's field of view. Together they deliver continuous, hands-free air cylinder content monitoring without requiring the user to look away from the task at hand. The system is designed for the MSA MMR 4500 SCBA series. Labels on the transmitter show ETL Listed and FCC ID P9R-10031511 markings. The receiver label shows ASSY 10037792, AP208 REV 1. Green LEDs are visible on the receiver face in photos. Both units show light-to-moderate surface scuffs consistent with field use.

Frequently Asked Questions

What two components are included?

The MSA NightFighter SCBA Transmitter Module (P/N 10036995, Model 7-1219-1) and the MSA Nightfighter HUD Receiver Module (P/N 10037792, AP208 REV 1). Both units are included in this single listing.

What SCBA system and facepiece are required for these to work?

The Nightfighter HUD system is designed for the MSA MMR 4500 SCBA series paired with the MSA Ultra Elite Facepiece. It is not designed for use with other SCBA platforms or facepiece models. Buyers should confirm their specific MMR 4500 variant and facepiece revision are compatible with these part numbers before purchasing.

What batteries do these units require?

Each unit requires batteries to operate. The seller's original notes indicate AAA alkaline batteries for both units; however, some MSA documentation references AA batteries for the receiver. Buyers should verify the correct battery type for their specific units before use. Batteries are not included.

Have these been tested?

No. Evaluation is visual inspection only. Function testing has not been performed. These are being sold as used, untested components. Verify suitability before use.

Are manuals or mounting hardware included?

No manuals or instruction sheets are included. No additional mounting hardware beyond the units themselves is included.

Will modifying these units affect their safety ratings?

Yes. MSA documentation indicates that altering the components voids the intrinsic safety rating. These units should not be modified.
