Upgrading Trilogy Locks to Networx Access Control

Alarm Lock upgrade kits allow your customers to extend their level of access control, security and programming to network capable proximity/keypad equipped electromechanical locks, all without the expense of total replacement of existing hardware.

Within the security industry, it is difficult for end users of electromechanical products to remain up to date because of the rapid advances in technology. As a result, it is not practical to have a customer replace locks every few years to have the most advanced security.

However, there is a point in time when the existing security no longer provides the required protection. For example, a relatively new feature that has become a requirement for many educational facilities is emergency global lockdown. These facilities also need the ability to delete users from all of the locks at one time. Networked locks can provide those features as well as an audit trail and the ability to schedule programming updates and audit trail retrievals to run automatically during off hours.

When that time comes, Alarm Lock has developed an upgrade path for their cylindrical and mortise electromechanical locks that provides a cost savings alternative to complete replacement. Alarm Lock upgrade kits are designed for all of the Trilogy models starting with the DL2700 cylindrical and the DL3500 Series Mortise Locks to bring them on par with the latest version of the Networx PIN (DL610026DUP- GRD cylindrical/DL650026DUP- GRD mortise) or PIN/prox (PDL610026DUP- GRD cylindrical/ PDL650026DUP- GRD mortise) Wireless Access Locks.

The component kits to upgrade a Trilogy cylindrical model to a Networx lock includes a DL 6100 or PDL6100 outside digital keypad housing (with prox for PDL61000), an inside housing with radio, mounting plate and four “C” cell battery pack. Similar components are in the Trilogy mortise lock upgrade kits. The upgrade kits reuse existing Trilogy lock bodies, levers, cylinders, latches (if cylindrical) and strike plates.

Upgraded Alarm Lock Networx locks can be operated along with the earlier models using the DL-Windows database V4.1.x or higher. This permits a seamless upgrade path for facilities having different models of the Trilogy locks.

Alarm Lock Trilogy cylindrical lock models that can be upgraded include the DL2700, DL2800, DL3000, PL3000, PDL3000, PDL3000K, DL3200, DL5300 and the PDL5300. Alarm Lock Trilogy mortise lock models that can be upgraded include the DL3500 and the PDL3500.

The DL2700, known as the T2, is a standalone electromechanical cylindrical keypad operated lock that was introduced in 1994 with 17 users and enhanced to 100 users in 2005. Technical advances at the time included up to 100 multi-level user codes including the Master, 10 Manager, 90 User and 3 Service Codes. Codes can be organized by groups or individually. User codes could be from three to five digits. The T2 is keypad programmable at the door and equipped with key override. A two-wire remote override could provide access for individuals who were not given a code.

Depending upon the lock model being upgraded, door prep hole modification may be required in order to install the Networx lock. For example, if the DL2700 has a ¾” diameter connector wire/cable hole, it must be enlarged to one inch in diameter. Enlarging the hole will not affect the NFPA 80 rating on a fire rated door.

Up to 2,000 doors equipped with Trilogy Networx Locks can be programmed using the Alarm Lock DL-Windows software. This free software can be used to program up to 5,000 users with three- to six-digit numeric PIN code and most HID format proximity identification cards or badges. They can communicate wirelessly via Ethernet or 802.11B/G, permitting programming at a single location instead of at each lock. To protect against tampering or interference, there is a 128bit AES PC encryption with proprietary RF-link lock to Gateway communication encryption. The event log can contain up to 35,000 events. Additionally, the Networx locks have extended battery life expectancy to exceed five years under normal operation.

For this article, we will upgrade a Trilogy DL2700 (T2) cylindrical lock to Networx PIN and prox model PDL6100. To upgrade the T2, the lock must be removed from the door.
