MORX MP-4 Plastic Exit Button (NO/NC/COM)

Overview

The MORX MP-4 is a square plastic push button marked DOOR EXIT, fitted on the inside of an access-controlled door so people can leave without a card or fingerprint. Pressing it releases the lock through the access controller or breaks the lock supply directly. It is a common choice for offices, apartments, schools and shop back doors where many doors need to be fitted and a metal finish is not required.

Is it right for you?

• It suits an indoor door where the exit side needs a simple release button.
• It is made for hollow doors, so plan a cavity or back box behind the plate.
• It switches up to 3 A at 36 V DC, which covers the exit input of typical controllers and a fail-safe electromagnetic (EM) lock.
• If you want a metal finish, MORX also makes a square stainless steel exit button.

Key features

• Mechanical push button with NO, NC and COM contacts.
• Contact rating 3 A at 36 V DC maximum.
• Mechanical life tested to 1,000,000 presses.
• Panel made of a fireproof material.
• Standard 86 × 86 mm plate, 25 mm deep, 0.15 kg.
• Rated for -10 to 55 °C.

What else you need

An access controller or standalone reader with an exit input, or a fail-safe EM lock whose supply the button can break. Either way the switched load must stay within 3 A at 36 V DC. The MP-4 is the exit button for a MORX 600 lbs EM lock door.

Installation

Fix the plate over a cavity or back box in a hollow door or wall. Wire the button to the controller’s exit input, or in series with the lock supply for a fail-safe lock. The button takes no power of its own.

Before you buy

• The specification table lists the contacts as NC/COM while the model name says NO/NC/COM. If you need the NO contact, check the terminals when the button arrives.
• Keep the switched load within 3 A at 36 V DC.
