The DV-100 is a rebranded Wheelock message unit that was used in conjunction with the MXL until 1998, and mounted in an external cabinet.
randomperson Fire Alarms on Instagram: "Cerberus Pyrotronics MXL". The DV-100 is the smaller black panel.

The VoiceCom seems to be an original Cerberus Pyrotronics product and looks different, and uses a different message module.
The buildings in the videos in the original post are too large for a VoiceCom.
This video is at Walt Disney World’s Wilderness Lodge resort main building - Copper Creek. (built 1994)
Pull stations are MSI-10B’s.
Detectors are ID-60P’s.
Signals are Wheelock E-7070-WM-24 speaker/strobes. (and GX90 mini-horns in the rooms, but the original post explains why they’re not sounding.)
In 1998, the DMC-1 message card was released. It mounts as a card in the MXL enclosure.
