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...

The choice of lock mechanisms requires electronic access control for dual credentials, scheduling capability and audit trail. He would like a four-level security hierarchy, with himself at the top, then the company manager, the office and manufacturing managers and the employees.
Because of the wall construction, two standalone electronic access control locks are most practical. Then there are two key questions. What functionality is the customer willing to pay for? What lack of functionality is the owner willing to have someone do?
The most basic dual credential standalone lock with scheduling and audit trail would be a keypad and card mortise lock. This basic model for his application would require programming at the lock.
The next step up would be a software-driven PC with data transfer to and from the computer. Employees could be enrolled, scheduled and deleted at the computer. Each door lock’s information could then be sent either directly from a laptop computer or using a data transfer mechanism and uploaded to each lock as necessary. At each lock, the audit trail can then be downloaded.
The up-to-date option is the wireless networked locks that would provide almost real-time programming capability and dissemination of information. All of the programming is entered using a computer that is wirelessly connected to each of the locks. When someone presents his or her card and user code, the computer screen shows the information. Users can be quickly deleted and locks can be put into lockdown or passage mode. The condition of the batteries can be seen to know when the time comes for replacement instead of using a set replacement date.
Handleset install time is about 1 hour for an average. Programming time is additional.
SCENARIO 4: X-Ray Room
The fourth scenario is medical facility that wants to provide “touchless entry” for rooms into which wheelchair and gurney-bound patients will be taken, such as X-ray and nuclear medicine rooms, including MRI and PET Scans. The reason for these facilities to have “touchless entry” is to eliminate the possibility of accidentally injuring the patients. As a secondary benefit, this reduces the possibility of damaging the door, jamb, door hardware or the means of transportation.
These single-door entry rooms are within a secured area. Patients are led or transported to the procedure room. The rooms are equipped with four-foot wide doors that open in. In this facility, the wood door and jamb are not fire rated. A storeroom function mortise lockset provides security. A surface-mounted closer is installed onto the interior side of the door.
Obtaining touchless access requires a low energy power door operator to open and close the door once the locking mechanism is released. There are two options for the latching mechanism: electrifying the mortise lock or purchasing an electric strike. To activate the opening, a touchless activation switch will be installed onto the exterior and interior sides of the door. Since these rooms are already within the secured portion of the medical center, there is no need for badge readers.
Important: The lock mechanism must have manual operation where rotating a inside lever retracts the latch mechanism permitting free egress.
For this inswing installation, there are two options: an electrified mortise lock with latch retraction or an electric strike to operate in conjunction with the mechanical mortise lock using a low power door operator to open and close the door. The power door operator must have a relay that will unlock the electric strike or electrified mortise lock prior to opening the door.
Installation time for a low power door operator is between 1-4 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.
To unlock the lock mechanism, Command Access is introducing its Model LPM180 electrified mortise, a 24VDC standard mortise prep lockset that has complete latch retraction. Complete latch retraction is when power is applied, the latch bolt is retracted within the mortise body, permitting the door to be swung open by the power operator. The LPM180 does not require special door prep or trim. This solenoid powered failsecure mortise lock is field handable.
