Choosing the “right” door hardware for a specific application really begins with the customer. Examining the existing lock hardware to determine what can be properly used for the proposed application is the second step. First, it is most important to find out how the customer wants the door to...

SCENARIO 2: Hotel Entrance
The second scenario is a niche hotel being converted from mechanical locks to electronic locks. Guest rooms and some office doors are being equipped with wireless electromechanical locks operated by Smart cards. Some of the offices are being equipped with wired networked locks.
There are narrow stile aluminum glass doors at each of the three side entrances. Each entrance is equipped with a rim exit device, and the rim cylinder requires a room key to gain entrance. The level of security is almost non-existent as so many room keys have not been returned.
The mechanical locks on these three narrow stile aluminum glass doors will be replaced with electromechanical lock mechanisms having readers to enable the hotel-issued room Smart cards to gain access.
Power is available to each of the doors. The wireless network reaches each of the doors, permitting the system to limit access to the currently issued Smart cards.
There are a number of choices for electronically controlling access. These include:
- A handleset with built-in contactless reader connected to the exit device. Entrance would be gained by presenting the smart card, which unlocks the lock, permitting rotation of the handle that retracts the exit device bolt.
Handleset install time is about 1 hour for an average.
- A separate wall-mounted contactless reader that controls a magnetic lock. The exit device would be disabled. A passive infrared request to exit device positioned above the door on the interior side would release the magnetic lock. Some building codes and LAHJs require an additional emergency exit button when a motion sensor is to be installed.
- A separate wall-mounted contactless reader that controls a magnetic lock. The exit device would be disabled, with the push bar operating as REX switch.
Wall-mounted contactless reader and a magnetic lock install time is about 1-3 hours for an average. This time can vary significantly if the 110VAC power source is not easily accessible. Whenever possible, install the power supply in an electrical or storeroom, or above a drop ceiling (non-plenum) in order to not have components easily visible.
- A separate wall mounted contactless reader that controls a new exit device equipped with electrified latch retraction.
- A separate wall mounted contactless reader that controls the existing exit device modified with electrified latch retraction.
Wall mounted contactless reader and an electrified exit device install time is about 1-3 hours for an average. This time can vary significantly if the 110VAC power source is not easily accessible. Whenever possible, install the power supply in an electrical or storeroom, or above a drop ceiling (non-plenum) in order to not have components easily visible.
SCENARIO 3: Manufacturing Facility
The third scenario is a small manufacturing facility with two swinging entrance doors, one in the front and one in the rear. The poured concrete building has exposed walls and poured concrete filled jambs. The non fire rated, hollow metal exterior doors are equipped with mortise locks and cylindrical deadbolt locks. The mortise locks are equipped with knobs and rosette trim. The mortise pockets are approximately 6-1/2” tall and about 4-1/2” deep.
The company owns the building. Office personnel enter through the front door and manufacturing personnel enter through the rear door. Employees use a time clock to punch in and out. The total number of employees is approximately 100 with very little turnover.
The owner wants security and access control to permit only authorized employees right of entry at their appropriate times. He wants dual credentials, scheduling and audit trail. One of his goals is to eliminate the time clock. He cares only the time an employee enters as the workflow will demonstrate the amount of time each manufacturing employee is on the job. He also wants locks installed onto exterior doors that are to some degree vandal and weather resistant.
As the clock struck midnight this New Year’s Eve, the electronic locking systems decided to malfunction at both the Gramercy Park Hotel in New York and a Marriott hotel in Denver. It is not know yet...
