The AES MOD-2B is a 2-button illuminated call module for select AES Global modular intercom and access-control systems. It is used where a compatible AES modular entry station needs two call buttons for residents, users, units, departments, gates, doors, or call destinations.
Public product information lists MOD-2B as an AES 2-button module for the modular series. It is commonly described as an optional add-on for customizable AES cellular, GSM, or wireless multi-button modular intercom systems. Because AES modular parts can look similar from the front of the panel, this module should be selected by part number, panel layout, button count, wiring connection, and system type.
The MOD-2B provides two illuminated call buttons for compatible AES modular intercom systems. In a properly configured installation, each button can be assigned to a user, apartment, resident, office, department, gate, door, or call destination depending on the AES system and programming.
This module works with the rest of the AES entry system, including the cellular, GSM, IP, DECT, or multi-button communication module, speaker/callpoint module, microphone circuit, power supply, relay outputs, gate or door release wiring, antenna or network connection, and site programming. It is a button module, not the complete intercom or controller.
This 2-button illuminated module may be used with the following applications where the current AES documentation, panel layout, or installer plan confirms fitment:
Important: Do not assume MOD-2B fits every AES intercom or every AES modular panel. Confirm the exact AES system, panel layout, button wiring, communication module, and programming requirements before ordering.
AES modular systems use several front-panel modules that may look similar once installed. A 2-button module, 1-button module, 3-button module, 4-button module, 5-button module, speaker/callpoint module, cellular module, keypad/prox module, information window, postal cutout, and blank module are different parts and should not be substituted without checking the AES parts documentation.
| Part / Component | Common Description | Interchangeability Note |
|---|---|---|
| MOD-2B | 2-button illuminated call module | Use where the AES modular system calls for this 2-button module |
| MOD-1B | 1-button module | Single-button module, not the same as the 2-button module |
| MOD-3B | 3-button illuminated call module | Related button module with a different button count; not the same part |
| MOD-4B | 4-button illuminated call module | Related button module with a different button count; not the same part |
| MOD-5B | 5-button illuminated call module | Related button module with a different button count; not the same part |
| MOD-CP | Callpoint / speaker module | Speaker/callpoint module, not the 2-button module |
| MOD-MULTI-PX-KP | Data keypad and 125 kHz prox module | Credential-entry module, not a 2-button call module |
The AES MOD-2B should be ordered only when the AES modular panel layout and system documentation call for the 2-button illuminated module. A different button-count module, speaker/callpoint module, keypad/prox module, or cellular communication module may not be interchangeable even if it fits in the same modular system family.
If one or more buttons do not call correctly, check the main communication module, resident or user programming, button wiring, connector condition, 24V power where applicable, moisture, corrosion, SIM/account service, antenna signal, and relay/access-control setup before replacing the button module.

Before replacing the MOD-2B, confirm whether the issue is with the button module, the wiring, or the main AES communication module. A button that does not call may be caused by a failed button, loose harness, damaged connector, incorrect resident programming, disabled user, low power, moisture, corrosion, or a problem in the cellular/GSM/IP communication module.
Outdoor intercom modules commonly fail from water intrusion, corrosion, insects, damaged gaskets, loose wiring, and UV exposure. Inspect the panel seal, module gasket, label area, connector terminals, and wiring strain relief before installing the replacement module.
The AES MOD-2B should be installed by a qualified access-control or gate technician familiar with AES modular intercom systems, low-voltage wiring, button circuits, resident programming, relay outputs, gate operator inputs, door release circuits, and site security requirements.
For apartment buildings, gated communities, commercial entries, and controlled access points, confirm the full access sequence before putting the system into service. Button call routing, visitor calling, two-way audio, keypad access, prox access, postal access, fire access, schedules, and gate or door release functions should all be tested without bypassing required safety or security devices.
The AES MOD-2B is a 2-button illuminated call module for select AES modular intercom and access-control systems.
No. MOD-2B is a call-button module. It does not replace the main cellular, GSM, IP, or DECT communication module, speaker module, power supply, antenna, relay wiring, enclosure, or full access-control system.
Yes. MOD-2B is commonly listed as a 2-button illuminated call module for compatible AES modular intercom systems.
No. MOD-2B is the 2-button module. MOD-3B is the related 3-button module and should not be treated as the same part.
Yes. Button call problems can be caused by wiring, loose connectors, resident programming, low power, moisture, corrosion, the main communication module, SIM or network service, or relay/access-control setup.
Check the AES system series, panel layout, wiring harness, button assignments, label order, main communication module, power supply, moisture, corrosion, and programming before replacing the module.
Yes. Installation may involve low-voltage wiring, button circuits, resident programming, panel sealing, relay testing, and gate or door release verification, so it should be handled by a qualified access-control or gate technician.
