Edwards (10ANN/B) Semi-flush annunciator wall box.

The Edwards 10ANN/B is a 10-position semi-flush annunciator backbox cabinet for EST3 fire alarm system annunciators. First, this is a passive sheet-metal enclosure — not a standalone annunciator. Specifically, the 10ANN/B houses up to ten EST3 LCD or LED display modules in a wall-mounted, semi-flush configuration. Therefore, the annunciator itself (display modules, controller) is ordered separately.

What the Edwards 10ANN/B is

This is a semi-flush mount cabinet for EST3 remote annunciators. As a result, it suits lobby, fire command, and remote-display installations where the enclosure should sit nearly flush with the finished wall. In addition, the cabinet accepts a mix of 3-LCD and 3-LCDXL1 display modules plus EST3 annunciator support hardware.

What this part is NOT

However, the 10ANN/B is not an annunciator and does not include display modules, a controller, or wiring harness. Also, it carries no standalone UL fire-alarm listing — listings apply at the EST3 system level once the modules are installed. Furthermore, the “/B” designator indicates the backbox (the surface-mount sibling is “/B-S”).

Compatibility

The 10ANN/B accepts Edwards EST3 annunciator modules including 3-LCD, 3-LCDXL1, and supporting EST3 cabinet hardware. In addition, slide-in labels behind the LCD displays support mass-notification labeling configurations.
