Commercial Access Control Push Button with Mechanical Pneumatic Hold Time, Stainless Steel Faceplate, Anodized Aluminum Button and NO/NC Contacts – 12 Configurations Available

The BEA 10ACPBDA Series Pneumatic Push Buttons provide reliable, manually operated door-release and activation control for commercial access control systems, electromagnetic locks, and compatible automatic door applications.

Featuring a built-in mechanical pneumatic timer, these commercial push buttons maintain their selected contact condition for an adjustable 2 to 60 seconds after activation.

Unlike electronic timed-release switches, the BEA pneumatic mechanism does not require a separate electrical power source to operate its timer.

Each assembly features a durable stainless steel faceplate with a colored anodized aluminum push button, providing dependable operation in commercial and institutional environments.

Available configurations include red, green, or blue buttons, 1-5/8-inch or 2-inch button diameters, and jamb-size or single-gang mounting plates.

Red and green configurations feature “PUSH TO EXIT” text, while blue configurations display an accessibility symbol.

Designed for professional access control applications, the BEA 10ACPBDA Series provides both normally open and normally closed contact options and a manufacturer-rated 5A at 125VAC switching capacity.

The pneumatic mechanism has been tested for more than one million operations, making it a durable option for frequently used commercial entrances.

The series is listed to UL 508 / CSA C22.2 No. 14-10 through MET Labs, File E113051, and is intended for indoor installations.

Important: Select the correct complete part number, 10ACPBDA1 through 10ACPBDA12, according to the required button diameter, color, and faceplate style.

Adjustable Mechanical Pneumatic Timer

The primary feature of the BEA 10ACPBDA is its integrated pneumatic hold-time mechanism.

When the button is pressed, the internal electrical contacts change state. The pneumatic timer then controls how long the contacts remain in the activated condition before returning to normal.

Timer Specifications

Turning the brass adjustment screw clockwise increases the timer hold interval.

Because the system is mechanical, the exact hold time may vary with temperature and environmental conditions.

Important: The 2–60-second adjustment controls the duration of the electrical contact activation. It is not a delayed-egress authorization timer and should not be confused with a 15-second delayed-egress locking system.

Commercial Request-to-Exit Applications

The BEA 10ACPBDA Series can provide manual release control for properly designed electronic locking systems.

A common application is an access-controlled door equipped with an electromagnetic lock.

When an individual presses the button, the switch changes its electrical contact state for the configured interval.

In an appropriately designed normally closed magnetic-lock release circuit, this action can interrupt power to the lock, allowing the door to be opened.

Typical Applications

• Electromagnetic lock release

• Commercial request-to-exit controls

• Electronic access control systems

• Secured interior doors

• Institutional exit buttons

• Commercial door-release stations

• Compatible automatic door control inputs

Life-Safety Notice: A pneumatic push button is only one component of a complete egress system. Required independent release devices, fire-alarm interfaces, power-loss behavior, and release timing must be provided as applicable under local building and fire codes.

Stainless Steel Faceplate & Aluminum Button

Each BEA 10ACPBDA configuration features a stainless steel mounting plate and a colored anodized aluminum button.

Construction Features

• Stainless steel faceplate

• Anodized aluminum push button

• Commercial mechanical timing assembly

• Low-maintenance design

• Available narrow-jamb and single-gang configurations

• Red, blue, or green button styles

The faceplate and button configuration can be selected to coordinate with the building's door hardware and intended use.

Available Button Colors

Red – PUSH TO EXIT

Red configurations feature a red anodized aluminum button marked with “PUSH TO EXIT” text.

Available with both button diameters and mounting plate styles.

Blue – Accessibility Symbol

Blue configurations feature a blue anodized aluminum button with an accessibility logo.

These models are suitable for applications requiring the specified visual button identification.

The symbol alone does not establish ADA compliance; the complete installation must satisfy applicable accessibility requirements.

Green – PUSH TO EXIT

Green configurations feature a green anodized aluminum button marked with “PUSH TO EXIT” text.

Like the red models, they are available in both button diameters and mounting styles.

Button Diameter Options

1-5/8-Inch Button

The standard-size button provides a compact control surface for suitable door frames and wall locations.

2-Inch Button

The oversized button provides a larger activation surface for applications where a larger button is preferred.

Both options use the same pneumatic timing technology and switching specifications.

Mounting Plate Options

Jamb-Size Faceplate

The jamb configuration is designed for mounting on appropriately prepared narrow door framing, including compatible aluminum storefront frames.

Jamb Faceplate Dimensions

• Width: 1-3/4"

• Height: 4-1/2"

BEA's installation instructions describe mounting the assembly to an aluminum frame with two supplied #6-32 screws and using the included mounting template to establish the frame cutout.

Single-Gang Faceplate

The single-gang configuration is designed for standard single-gang electrical box installations.

Single-Gang Faceplate Dimensions

• Width: 2-3/4"

• Height: 4-1/2"

BEA specifies installation in an appropriately rated UL/CSA-listed Type 1 electrical box. The timer assembly must not be installed without a suitable box.

Normally Open & Normally Closed Contacts

The BEA 10ACPBDA provides two contact configurations.

Normally Closed (NC)

The circuit is normally closed and opens when the button is activated.

This configuration is commonly used for appropriate electromagnetic-lock power-interruption arrangements.

Normally Open (NO)

The circuit is normally open and closes when the button is activated.

This configuration may be used to provide a request or activation signal to a compatible controller.

BEA's installation guide identifies the red wires as the NC circuit and the white wires as the NO circuit.

The correct circuit depends on the complete access control design.

Important: Switch contacts do not produce electrical power. The connected lock, controller, or automatic door system still requires its own appropriate power source.

Installation & Ordering Considerations

Before selecting a BEA 10ACPBDA button:

• Confirm the complete manufacturer part number.

• Select red, green, or blue button identification.

• Choose the 1-5/8-inch or 2-inch button diameter.

• Determine whether jamb or single-gang mounting is required.

• Verify sufficient clearance for the pneumatic timer assembly.

• Select the correct electrical box or frame preparation.

• Confirm compatibility with the connected locking or control circuit.

• Verify that electrical loads do not exceed the contact rating.

• Determine the required release duration.

• Adjust the timer to the intended interval.

• Test the actual hold time under operating conditions.

• Verify that the lock or controller responds correctly.

• Confirm all required emergency-egress functions operate independently.

• Follow all applicable building, fire, accessibility, and electrical requirements.

Important: A mechanical pneumatic release switch must not be substituted for a required listed delayed-egress controller, emergency release station, or other mandated life-safety device.
