MORX Electric Strike Lock, Fail Secure

Overview

The MORX Electric Strike Lock is a narrow electric strike that replaces the standard strike plate in a door frame and works with the existing mechanical lock or latch. When powered at 12 V DC the keeper releases and the door can be pushed open; it is fail-secure, so the door stays locked in a power cut. It suits wooden, metal and PVC swing doors with a lockset already in place, at offices, stores, server rooms and residential entrances.

Is it right for you?

• Suits doors that already have a mechanical lock or latch and swing 90 degrees.
• Suits doors that must stay locked when power fails (fail-secure). For a door that should release in a power cut, choose a fail-safe drop bolt instead.
• Suits a small 12 V supply: it draws 200 mA.
• If there is no existing lockset, the MORX electric rim lock is a surface-mounted fail-secure alternative.

Key features

• Fail-secure: power to unlock, so the door stays locked in a power cut.
• 12 V DC at 200 mA, so it runs from a small supply or a 12 V mini UPS.
• Stainless steel bolt structure.
• Surge protection (MOV, metal oxide varistor) on the coil, which protects the controller relay.
• For 90-degree swinging doors in wood, metal or PVC.
• Rated for -10 to 55 °C; weight 0.3 kg.

What else you need

• A 12 V DC supply such as the MORX Box+SMPS (12 V, 3.5 A).
• An access controller, standalone reader or exit button such as the MORX MS-1 that switches the strike supply or a controller input.
• Only if the door must still open electrically in a power cut, a 12 V battery backup such as a mini UPS with a 1 A output.

Installation

A locksmith or access control installer should fit it. The strike is mortised into the frame jamb, aligned with the latch of the existing lock, and wired to the switched 12 V supply. Published dimensions for this strike differ between documents, so measure the unit before cutting the frame.

Before you buy

• Measure the strike before cutting the frame: the published dimensions differ between documents.
• Because it is fail-secure, check local fire and escape rules. A fail-secure strike is normally paired with a lockset that always allows free exit from inside.
• It needs an existing mechanical lockset or latch to work with.
