Door Release Exit Push Button Green Mushroom Head Zinc Alloy Surface Mount Access Control

Exit push buttons are the standard egress device on access-controlled doors, fitted on the inside of the controlled area. When a person wishes to leave the secure side of the door, they press the exit button, which sends a signal to the access control unit or maglock to release the door lock momentarily and allow exit.

The green mushroom-head form factor is the most intuitive and recognisable exit button design: green universally signals safe exit or go, and the large mushroom-head profile is easily located and activated without requiring precise finger placement, which is important in emergency and low-light situations.

Zinc alloy construction provides the durability and weight expected of a security-grade access control device. Unlike plastic buttons that can be damaged by repeated forceful pressing, a zinc alloy button withstands years of regular use in commercial environments.

Surface mounting suits installations where the wall or door frame does not have a flush back box at the exit button position, or where the installation is in a visible, prominent position where the button needs to be both functional and visually clear.

Exit buttons are a regulatory requirement on maglock systems in buildings subject to UK fire safety regulations: the door must have a means of immediate manual release (often the exit button) that does not require a credential, key, or code to operate.

For access control installers fitting door release exit buttons on maglock and electronic latch systems across London and the UK, the ACM-K15BG provides the green mushroom surface-mount exit button in commercial-grade zinc alloy.
