Code Blue 40079 10 Amp NightCharge Replacement Charger
Overview
The Code Blue 40079 is a 10 Amp NightCharge replacement charger delivering 24V DC output, built to replace failed or aging charging units in Code Blue emergency phone and paging systems. If a tower or wall-mount unit is throwing low-voltage faults or the paging amplifier is underpowered, swapping in the 40079 restores the correct 24V DC supply without replacing the whole enclosure. It fits deployments where the original charger has degraded from continuous outdoor duty cycles — parking structures, campus call stations, and industrial yards running Code Blue hardware around the clock.
Compatibility
The 40079 is a Code Blue-branded replacement part and accessory, matched to systems using a 12-24V DC paging amplifier configuration. Confirm your existing charger's part number and voltage rating against the 40079 spec (24V DC, 10A) before ordering — Code Blue's charger lineup has changed part numbers across production runs, so matching the current part number on your unit's data plate is the reliable way to verify fit rather than assuming by model family.
Installation Notes
This unit outputs 24V DC at 10A. Systems that were originally provisioned with a different voltage or amperage charger should not substitute the 40079 without confirming the amplifier and battery bank are rated for the same output — mismatched charger output can undercharge or overstress the battery bank in an emergency phone tower.
Sourced through Code Blue's product line alongside the broader emergency communication systems category, the 40079 is a straightforward drop-in for maintenance and repair work rather than a new-system component. Pair it with Code Blue replacement accessories if you're servicing multiple towers in the same maintenance cycle. For teams planning charger replacement schedules across a campus deployment, a broader emergency phone maintenance guide is worth reviewing before bulk ordering. If the fault traces back to the amplifier itself rather than the charger, check compatible Code Blue paging amplifiers before committing to a charger-only fix.
