JS-DM853 Mushroom Head Exit Push Button

The DM851 is a mushroom head request-to-exit push button built on an 86mm x 50mm x 25mm panel. The faceplate is 1.8mm SS304 stainless steel with a sandblast finish, and the mushroom actuator is 2mm thick, available in green or red so the release point stands out on any door frame. An 18mm thick mushroom version is available as an option for a taller, easier-to-hit press. The NO / NC / COM dry contact wires directly to magnetic locks, electric strikes, door holders and access controllers.

Specification

Why Choose a Mushroom Head Button

A dome or mushroom actuator gives a wider press area than a flush button, so staff, visitors and gloved hands release the door on the first push. The 86 x 50mm panel keeps the button slim on narrow frames while leaving enough plate area for secure two-screw mounting. Choose green for a standard exit marking or red for emergency and alarm-flagged doors.

Wiring and Matching

Connect COM and NO to the controller request-to-exit input for a normal release signal, or use NC for fail-safe monitoring circuits. The unit is a dry contact device, so no external power is needed for switching; the 12V DC rating refers to the switched circuit. Combine the DM851 with magnetic locks, electric bolt locks, electric strikes and exit alarm devices for a complete door control package.
