MORX Drop Bolt Lock with Timer and Feedback, 5-Wire Fail Safe

Overview

The MORX Drop Bolt Lock with Timer and Feedback (model BL-C2001 B) is an electric bolt fitted in the top frame of a door. With power applied the 15 mm bolt drops into the strike and locks the door; when power is cut it retracts, so it is fail-safe. A built-in relock timer and a 5-wire connection with a status (feedback) output suit it to doors run by an access control panel, including glass office entrances and cabin doors.

Is it right for you?

• Suits glass, aluminium, wooden and metal doors, including double-acting doors that swing 180 degrees, where an electromagnetic (EM) lock or strike is impractical.
• Suits doors that must unlock in a power cut (fail-safe). If the door must stay locked when power fails, choose a fail-secure strike or rim lock instead.
• Suits panels that want to know the door state: the feedback wire reports the bolt position for door-held-open or forced-door alarms.
• If you do not need a status output, the MORX 2-wire drop bolt with timer has simpler wiring.
• Frameless glass needs a bracket for the strike, or the MORX frameless glass door bolt instead.

Key features

• Fail-safe: power to lock, so the door releases when power is cut.
• 12 V DC, with a start current of 960 mA and a standby current of 130 mA.
• Bolt of 15 mm throw and 15 mm diameter.
• Relock delay of 0, 3, 6 or 9 seconds, set as printed on the lock label, so the door relocks a few seconds after release.
• 5-wire connection with feedback, so the panel can see whether the bolt is home.
• Tested to 500,000 cycles.
• Aluminium face plate of 205 x 35 x 40 mm with a line finish; strike plate 90 x 25 x 3 mm; weight 0.9 kg.

What else you need

• A regulated 12 V DC supply rated above 1 A per lock, sized for the 960 mA start current, such as the MORX Box+SMPS (12 V, 3.5 A).
• An access controller, standalone reader or exit button to switch the lock; the lock label shows a push-button input wire.
• Only for frameless glass, a glass bracket for the strike, such as the MORX U Bracket for Drop Bolt Lock. The bracket model and glass thickness are not published, so confirm fit.

Installation

An access control installer or locksmith should fit it. The lock body mounts in or on the top frame and the strike plate in the top rail of the door, aligned so the bolt drops cleanly. The five wires are run to the supply, the controller and the feedback input, and the relock delay is set on the lock. It is rated for 0 to 90% humidity, non-condensing.

Before you buy

• Size the supply for the 960 mA start current, not just the 130 mA standby figure.
• Frameless glass doors need a glass bracket for the strike.
• Fail-safe only: the door is unlocked whenever power is lost.
