MORX Drop Bolt Lock with Timer, 2-Wire Fail Safe

Overview

The MORX Drop Bolt Lock with Timer, 2-Wire is an electric bolt for the top frame of a door that locks while powered and unlocks when power is removed, so it is fail-safe. It has a built-in relock timer and only two wires, the supply pair, so there is no status (feedback) output. It suits glass, aluminium, wooden and metal doors, including double-acting doors, in offices and cabins that do not need door-state monitoring.

Is it right for you?

• Suits doors where an electromagnetic (EM) lock or strike cannot be used, such as double-acting glass doors.
• Suits simple setups that switch the lock supply from a reader or exit button and do not need to know whether the bolt is home.
• Suits doors that must unlock in a power cut (fail-safe). For a door that must stay locked without power, choose a fail-secure strike or rim lock.
• If you want door-held-open or forced-door alarms, choose the MORX 5-wire drop bolt with timer and feedback.

Key features

• Fail-safe: power to lock, so the door releases when power is cut.
• Built-in timer, so the door relocks on its own after release.
• Two-wire connection: supply only, which keeps wiring simple.
• For glass, aluminium, wooden and metal doors, including double-acting doors.

What else you need

• A regulated DC supply. The voltage and current for this version are not stated by the manufacturer, so confirm them from the lock label before choosing it.
• An access controller, standalone reader or exit button such as the MORX MS-1 that switches the lock supply.
• Only for frameless glass, a glass bracket for the strike, such as the MORX U Bracket for Drop Bolt Lock; bracket fit is not published, so confirm it.

Installation

An access control installer or locksmith should fit it. The lock body mounts in the top frame and the strike in the top rail of the door, and the two wires are run to the switched supply. Confirm voltage, current, bolt size and dimensions from the lock label before cutting the frame.

Before you buy

• Voltage, current, bolt size and dimensions for this version are not published; check the lock label before choosing a power supply.
• No feedback output, so it cannot report door state to a panel.
• Fail-safe only: the door is unlocked whenever power is lost.
