MORX MPSM-1 Plastic Exit Button with Back Box (NO/NC/COM)

Overview

The MORX MPSM-1 is a plastic exit button supplied with its own back box, so it can be surface mounted where there is no cavity behind the wall or frame. It has normally open (NO), normally closed (NC) and common (COM) terminals, so it can signal a controller or switch a lock supply directly. It suits solid masonry walls, glass partitions with a side wall, and retrofit jobs where the cable runs on the surface.

Is it right for you?

• Suits a solid wall or any place with no cavity behind the button.
• Suits surface-run cable, as on retrofit jobs.
• Suits direct wiring in series with a fail-safe lock supply, thanks to the NC contact, within the rating marked on the button.
• For a flush fit in a hollow door or partition, the MORX MP-4 plastic button has published dimensions and rating but no back box.

Key features

• Plastic button housing.
• Back box included, so the button can be surface mounted.
• NO, NC and COM contacts for a controller exit input or direct lock wiring.

What else you need

• An access controller or standalone reader with an exit input, or a lock supply circuit to switch.
• A two- or three-core cable depending on whether the NC contact is used.
• No power supply: it is a switch with no electronics.

Installation

An access control installer or electrician should fit it. The back box is screwed to the wall, the cable enters the box, and the button plate is fixed over it. Dimensions and contact rating are not stated by the manufacturer, so confirm the back box size and the rating on receipt before planning cable entry and the switched load.

Before you buy

• Dimensions, contact rating and button mechanism are not stated by the manufacturer; confirm them on receipt.
• Keep the switched load within the rating marked on the button.
