Electronic Access and Storefront Doors
A medical clinic needed to control access to a series of suites, each entered through a single storefront door. Since the doors also are the exits, they must remain unlocked during business hours. The solution was to integrate a Securitron DK-26 digital keypad system with an Adams-Rite 8800 Series exit device with electrified retraction.

Recently I was asked to provide an access solution for a medical clinic. The clinic consisted of a number of suites sharing a long hallway. The entry of each suite is through a single storefront (aluminum and glass) door. The door also acts as the means to egress so “remaining unlocked during business hours” is essential.

As the number of persons leaving the company having access to keys grew, so did the amount of time required to manage keys and the expense to rekey a suite each time a termination occurred.

An interim solution was to limit key issuance to staff employees who by nature were more likely to be long-term employees. This presented a problem as some employees often arrived earlier than staff employees.

When discussing the situation with the building representative, auditing initial access into each suite was determined not to be an issue. I recommended installing a non-audit trail or time clock capable digital keypad access control system for each suite entry.
