MORX MS-2 Stainless Steel Exit Button (NO/NC/COM)

Overview

The MORX MS-2 is a square-plate push button fitted on the inside of an access-controlled door so people can release the lock with one press and leave without a card or fingerprint. Its 86 x 86 x 25 mm brushed stainless steel plate matches the footprint of a standard electrical switch plate, so it suits office corridors, reception doors and apartment entrances where the button sits on a wall beside the door rather than on a narrow frame.

Is it right for you?

• Suits a wall or partition beside the door with a cavity or back box for an 86 x 86 mm plate.
• Suits any door with an electromagnetic (EM) lock, drop bolt or electric strike and a controller that takes a dry-contact exit input.
• For a narrow door frame, the MORX MS-1 is the slim 92 x 28 mm version.
• If you need to wire the button in series with a fail-safe lock supply, confirm the NC contact first (see Before you buy).

Key features

• Contact rating of 3 A at 36 V DC maximum.
• Mechanical life tested to 500,000 presses.
• Brushed (wire-drawn) stainless steel panel with a steel button, for a finish that stands up to daily use.
• Rated for -10 to 55 °C and 0 to 95% relative humidity.
• Weight 0.1 kg.

What else you need

• An access controller or standalone reader with an exit input, or a lock supply circuit to switch.
• A cavity or back box behind the plate, as it is made for hollow doors and partitions.
• No power supply: it is a plain mechanical switch.

Installation

An access control installer or electrician should fit it. Plan a cavity or back box behind the plate, fix the plate, and run the cable to the controller exit input or the lock circuit, keeping the load within 3 A at 36 V DC.

Before you buy

• The title lists NO, NC and COM contacts, but the published specification shows NO and COM output only. Confirm whether an NC terminal is present before designing a circuit that depends on it.
• Made for hollow doors and partitions; a solid wall needs a back box.
