According to the original equipment manufacturer (OEM), the CO monitor Model 65 has been discontinued and replaced with the Model 62, NSN 6665-01-710-6177, PN 62-542-R-TR, which comes with a relay. It has the same 4-wire system as the old model but comes with a trim ring, allowing it to fit into the same location where the previous model was installed.
New CO monitor
The relay enhances the safe operation of the modern burner units (MBUs) in the CK. If the CO monitor is activated, an alarm will sound and the MBUs will be disabled.
Before installing a new CO monitor, mark an expiration date (EXP month and year) on front of the CO monitor that is five (5) years from date of installation into the CK. Don’t use the date manufactured, as in the past. This procedure isn’t in the TM, so make a note until the next revision of WP 0149 of TM 10-7360-226-23 (Oct 18), which will include the Model 62.
