Door Release Button SCOT BT-4 — SCOT wired push button for door release

SCOT BT-4 is a wired door release push button intended to control electric door strikes and access control systems. The device provides a momentary contact when pressed, sending a simple signal to unlock or release a door. It is designed for fixed installation close to entry points, intercoms, reception desks or security panels in residential and commercial buildings where a manual release of an electronically secured door is required.

Advantages

The SCOT BT-4 offers a compact, low-profile design that is easy to install and connect to existing access control wiring. Its momentary action reduces the risk of leaving a door unintentionally unlocked and the wired connection ensures a reliable electrical signal without dependence on batteries or wireless links. The button is suitable for standard mounting positions and integrates with common electric strikes and control panels.

Suitable for

• Manual door release near entrance doors and gates
• Integration with intercom systems and reception desks
• Use with electric strikes, maglocks and access control panels that accept a momentary contact
• Residential buildings, small offices, retail premises and service counters

When it may not be suitable

This wired push button is not suitable where wireless control or remote activation over a network is required. It also may not be appropriate for installations that demand vandal-resistant hardware or heavy-duty industrial enclosures; in such cases a reinforced or tamper-proof release button should be chosen. Compatibility must be checked if the access control system requires a specific voltage or contact type other than a standard momentary contact.

Key specifications

• Function: momentary (push-to-make) door release switch
• Connection type: wired terminals for low-voltage access control wiring
• Intended use: indoor mounting near entry points and control panels
• Operating action: spring-return push button
• Compatible with: electric strikes, maglocks and controllers accepting momentary closure

How to use

Mount the SCOT BT-4 at a convenient, accessible location near the door or intercom. Connect the button to the access control system using the low-voltage wiring terminals: one wire to the release input on the controller and the other to the common/ground as required by the controller. After wiring, test the button by pressing to ensure it provides a momentary closure that triggers the door release. Secure the mounting and route cabling to avoid pinching or exposure to moisture.

What to consider before purchase

• Verify that your access control panel or electric strike accepts a momentary contact input
• Check required wiring voltage and polarity against your system documentation
• Assess the installation environment for the need of a vandal-resistant or weatherproof button
• Confirm mounting space and whether a flush or surface-mounted configuration is needed

Usage recommendations

Install the button within easy reach of authorized personnel and test regularly as part of access control maintenance. Use appropriately rated wiring and secure connections at the control panel to ensure reliable operation. If the location is exposed or subject to tampering, select a dedicated vandal-resistant model.
