Notifier DP-1B — blank dress panel in black, covering one tier of a CAB-4 series cabinet.
A CAB-4 enclosure is built from a 16-gauge steel backbox and a locking door in one of five sizes, from the mini AA of a single tier to the D of four, and few jobs fill every tier at first. The DP-1B closes an unused tier so the assembly stays dead-front and finished instead of exposing empty chassis space behind the door. Notifier also names it as the panel that covers a DAA2 or DAX series amplifier, or an AA-series amplifier, in its row.
- Covers exactly one CAB-4 tier, providing a dead-front surface
- Fits the AA and A one-tier, B two-tier, C three-tier and D four-tier cabinets
- Listed as a CAB-4 accessory beside the ADP-4B dress panel, VP-2B ventilator panel and BP2-4 battery plate
- Carries no wiring, terminals or address
- CAB-4 cabinets hold UL and ULC listing S635 and FM approval
It is not the BMP-1, which blanks one unused module position rather than a whole tier, nor the DP-DISP, the top-row panel used when a CPU2-3030D is installed, nor the ADP-4B annunciator dress plate for rows 2, 3 and 4.
