The Edwards 4ANN/B-S is a four-position surface-mount wallbox for EST3 remote annunciators. Specifically, it accepts a 4-position LED/LCD annunciator door and forms the surface-mount backbox for EST3-era lobby annunciators.
First, the 4ANN/B-S provides the steel backbox that mounts to a finished wall. Then the matching annunciator door bolts to the wallbox. As a result, an EST3 panel can drive a remote four-position annunciator at the building lobby or other monitoring location.
Verified Features
- Four-position surface-mount wallbox for EST3 remote annunciators
- 16-gauge cold-rolled steel construction
- Gray textured enamel finish
- Accepts standard EST3 4-position LED/LCD annunciator doors
- Surface mount (use a different door + wallbox combination for semi-flush)
EST3 vs EST4 — Important
However, the 4ANN/B-S is NOT the same as the EST4-era 4-4ANN annunciator. Specifically, the EST3-era part uses the “4ANN” prefix (no dash). The EST4 part uses “4-4ANN” (with a dash) and is a complete annunciator assembly, not a bare wallbox. Therefore, confirm whether the panel is EST3 or EST4 before ordering.
Sibling Wallboxes
Furthermore, the 4ANN/B-S has siblings in the EST3 annunciator family. For example, the 6ANN/B-S is the six-position surface wallbox. As a result, match the wallbox size to the number of annunciator positions you need.
Listings
The 4ANN/B-S is a passive enclosure. Therefore, it carries no standalone agency listing. Instead, it is covered under the EST3 system listing (UL 864) when installed with a listed annunciator door.
