Lessons learned at the LCN Low Energy Power Operators Workshop

This certification enhances the locksmith’s image as a security professional and provides another tool for winning future door operator business.


LCN Senior Swing™: This heavy duty electromechanical unit with a variety of mounting options, includes advanced digital controller and is suitable for exterior doors less than 200 lbs.

LCN Benchmark™: This versatile, easy-to- install unit can be mounted on either the push or pull side of the door and has a full set of installer-friendly adjustments.

LCN also offers a full line of accessories such as wired and wireless handicapped buttons, bollards and safety sensors.

The class devoted ample time to explore all the safety requirements and numerous configurations for LCN door operators and actuating equipment.

A particularly interesting handout we received was the LCN Product Application Guide, featuring illustrations and parts lists for various hookups of LCN operators in a variety of scenarios such as: Hospital hallways, Library Entrance; Employee Entrances; Smoke Evacuation Facilities; Restroom doors; Assisted Living Residences, etc. Of particular interest was interface information with Von Duprin Exit devices, electric strikes, power supplies and Schlage locks.

BENCHMARK INSTALLATION

I recently completed an installation of an LCN Benchmark III on one leaf of an interior pair of doors in an executive office environment.

In our shop, some mechanics prefer not to handle anything electronic. I told one of them that this was an LCN and to treat it like any other LCN door closer. He did a superb job mounting the unit and left all the interfacing for me. The door was previously controlled by a card reader and was equipped with maglocks.

The card access was to continue to be used, with additional requirements set forth by the owner. In this facility every employee is required to carry a photo-ID which is also an access control credential.

The owner wanted to limit who could activate the door operator. One reason was the door operator was not a toy, but everyone loves to play with it. Another reason was the security officer was concerned that when the door operator was used, the door remained open longer than if it were manually pulled or pushed open and then allowed to re-close. Additionally they realized the more the door operator was used, the faster it would require repairs. There were only a couple of handicapped individuals in the company, and the operator was installed for their comfort and convenience.

Interfacing the maglocks with the door operator was straightforward. The Benchmark III has a built-in setting which delays activation to allow for an electric locking device to release before triggering the operator.

I added an additional card reader on the egress side of the door, and programmed the system to provide the following sequence of operation. NOTE: Establishing the Sequence Of Operation and obtaining your client’s approval is the first and most important step in any door operator installation.

1. Manual Entry with valid card: Manual Egress at all times by pushing on the exit bar which cuts power to the maglock and sends a REX to the access controller.

2. Handicapped entry: Present appropriately programmed credential to the entry reader and door opens.

3. Handicapped egress: Present the appropriately programmed credential to the egress side reader and door opens.

The Benchmark III looks great, and the selection of adjustments allowed precise tuning of the operator’s performance.

The ‘Power Boost’ setting causes the door to pull shut when it has reached the latch position. Designed to overcome stack pressure, this little enhancement assured me that the door would pull itself up the maglock and re-secure after every operation. The client was impressed.

This class is beneficial to any locksmith who is involved with or who plans to become involved in the installation of door operators. Seeing the entire LCN line up close and learning the LCN philosophy for product deployment was very helpful. I service existing installations and frequently encounter LCN. Now I know more about the operation of these products.

The thorough review of the ADA served as a refresher course, and armed me with a new sales tool for creating future door operator business. The certification enhances my image as a security professional and differentiates our shop from the guy up the street. I intend to use the certification for my in-service training requirements.
