Edwards 4-2ANND Anunciator Door

The Edwards 4-2ANND EST4 Annunciator Door is a service replacement door assembly designed for Edwards EST4 4-2ANN remote annunciators. Edwards documentation describes the 4-2ANND as a metallic bronze annunciator door supplied with both the inner and outer doors.

The door is used with the two-space EST4 annunciator configuration. Certification documentation specifically pairs the 4-2ANND door with the 4-2ANNMT annunciator/backbox assembly.

EST4 Annunciator Compatibility

The 4-2ANND is specifically designed for:

4-2ANN Series Remote Annunciators

Edwards’ remote annunciator documentation identifies:

4-2ANND — Service replacement metallic bronze Annunciator Door for 4-2ANN annunciators.

The 4-2ANN configuration is the compact two-space arrangement within the EST4 remote annunciator family.

---

4-2ANNMT Compatibility

The associated annunciator enclosure is:

4-2ANNMT — Two-space annunciator wallbox/enclosure

California seismic certification documentation identifies the combination as:

4-2ANNMT backbox with 4-2ANND door.

Current project documentation also shows the 4-2ANND installed together with the 4-2ANNMT, 4-ANNCPU, and other EST4 annunciator components.

---

Inner & Outer Door Assembly

The 4-2ANND is supplied as a complete door assembly rather than only an exterior decorative panel.

It includes:

Inner Door

and

Outer Door.

The inner door supports the annunciator’s internal presentation and equipment arrangement, while the outer door provides the finished exterior closure for the annunciator enclosure.

---

Metallic Bronze Finish

The standard 4-2ANND uses a:

Finish: Metallic Bronze.

This finish matches the standard EST4 cabinet and annunciator appearance.

A third-party industrial parts listing likewise identifies the product as:

2-Space Annunciator Door — Bronze.

---

Two-Space Configuration

The 4-2ANND is intended for the compact two-space EST4 annunciator configuration.

The model numbering distinguishes it from larger annunciator doors:

4-2ANND: Two-space annunciator door

4-4ANND: Four-space annunciator door

4-6ANND: Six-space annunciator door.

This makes correct part-number selection important when replacing an annunciator door.

---

Service Replacement Component

Edwards specifically categorizes the 4-2ANND as a:

Service Replacement Part.

It is therefore intended primarily for replacement or servicing of compatible EST4 annunciator assemblies rather than functioning as a standalone fire alarm device.

The door contains no independent initiating, notification, network, or detection functionality.

---

EST4 Remote Annunciator System

EST4 remote annunciators provide remote fire alarm system status and operator controls at locations away from the main fire alarm control panel.

Depending on configuration, an annunciator assembly can contain components such as:

• LCD displays
• LED display/control modules
• Operator controls
• Network communication hardware
• Annunciator CPU components

The 4-2ANND provides the finished door assembly for the compact two-space version of this system.

---

Installation Information

The 4-2ANND installs onto the compatible 4-2ANN annunciator enclosure, particularly the 4-2ANNMT assembly documented by Edwards.

Typical replacement involves removing the existing annunciator door, inspecting the enclosure and internal annunciator equipment, installing the replacement inner and outer door components, verifying alignment and closure, and confirming unobstructed access to the annunciator display and controls.

Because the 4-2ANND is an enclosure component rather than an electronic module, it does not require a separate electrical address or operating power.
