Alarm Controls Corporation EB-3 Large Red Mushroom Button

Product Description

The ALARM CONTROLS CORPORATION EB-3 is a large red mushroom-head push button with two normally closed contacts. It is designed for use in access control, emergency stop, and door release applications where a highly visible, easy-to-actuate control point is required. The mushroom-head form factor provides a large activation surface that operators can engage quickly under urgent conditions. Electricians and low-voltage security technicians are the primary trades who specify and install this type of device in commercial and institutional settings.

The EB-3 is suited for commercial door control systems, emergency egress applications, and access control panels where a normally closed circuit configuration is standard. The dual normally closed contacts allow the button to break a circuit upon actuation, which is the typical logic required for emergency stop and door release functions. It is sold as a single unit and is appropriate for both new installations and replacement of existing mushroom-head push buttons in similar control systems.

Key Features

• Large red mushroom-head actuator for high visibility and quick activation
• Two normally closed contacts for standard emergency stop and door release wiring logic
• Single-unit packaging suitable for individual replacement or new installation
• Designed for commercial access control and egress control applications

Compatibility

Designed as an OEM-style replacement or new-installation push button for commercial access control, emergency stop, and door release systems that accept normally closed mushroom-head button devices.

Installation Notes

Installation is typically performed by a licensed electrician or low-voltage security technician. De-energize the control panel or access control system before wiring or replacing the button. Follow applicable NEC requirements for low-voltage control wiring. Verify that the normally closed contact configuration matches the logic of the receiving control panel before completing the installation.
