The Notifier DR-B4B is a two-tier blank (no-window) locking door for Notifier CAB-4 Series fire alarm cabinets. It ships in black with a lock and keys, and it accepts up to two chassis behind it.
First, the DR-B4B fits the B-size (two-tier) CAB-4 backbox. Then the door mounts with a pin-type hinge and a key-operated lock. As a result, panel internals are fully enclosed and access is restricted.
Unlike the DR-B4, the DR-B4B has no window. Therefore, it suits installations where visible status indication is not required or not desired. In addition, the blank face provides a cleaner appearance in finished spaces.
The door is fabricated from 16-gauge steel. Furthermore, the opening behind the door measures 24.062″ wide by 28.562″ high.
