Keypad Options: Standalone, Weatherproof, Dual Credential, Networked?

Alarm Lock offers several one- and two-credential digital access control keypads. These keypads are similar in shape to the Trilogy locks providing the end user with consistency in appearance and having the ability to offer a single manufacturer’s products. The DK3000 PIN Code keypad and the PDK3000 PIN/Prox ID Card Keypad have up to 2000 three- to six-digit user codes with multilevel security and a 40,000-event audit trail. These keypads have a real time clock enabling time scheduling according to time zones. They can be programmed at the keypad or personal computer.

For networked applications, Alarm Lock offers the Trilogy® Networx™ Wireless Keypads with NetPanel 2-Door Access Controller using PIN Code keypad and/or PIN/Prox ID Card Keypad. These networked keypads are hardwired to the controller and wireless from the controller to the gateway and computer. Features of Networx Keypads include global lockdown, passage mode, request-to-exit, door ajar and remote release options. The Alarm Lock keypads were introduced to provide end users the ability to operate electric strikes or magnetic locks and to offer an alternative for out opening doors.

The Prox ID card equipped keypads accept most HID proximity cards and key fobs. Users can be programmed to use a card only, code only or for a higher level of security, both card and code.

Sargent 4293 Installation

For this article, I was invited to the installation and wiring of a Sargent 4293 onto a hollow metal doorframe in the Dugmore & Duncan electronics lab and classroom in Corona, CA. The opening is equipped with a Norton 1601 BFXSN door closer, having a 3 to 6 power sizing.

A Sargent Exit Device with electric latch retraction, part number 56-8813F ETL 32D was installed using Rivnut fasteners to secure the device to the door. An electrification upgrade is available for the three-foot Sargent 80 Series Exit Devices. The kit for the three-foot exit device is Part Number R56AF.

A Securitron BPS-24-3, a three Amp, UL Class 2 listed, linear power supply that provides 24VDC filtered and regulated power was mounted onto the wall adjacent to the door. To run the wiring from the power supply and the keypad to the exit device, a McKinney QC Concealed Circuit Electric Hinge was installed. The McKinney electric hinge began as a model T4A3386, a 4.5” by 4.5”stainless steel ball bearing hinge. This eight-position electrified hinge is rated at 4 Amps continuous @ 24VDC.

The Sargent 4293 has five wires: red, black, blue, green and gray. The red wire is positive (+). The black wire is negative (-). The blue wire is the Main Relay C. The green wire is Main Relay N/O. The gray wire is Main Relay N/C. Since power is required to retract the rim latch, the Normally Open relay was wired to provide power for latch retraction.

A short raceway was drilled through this non-fire rated door from the center hinge wiring entry point to a point directly beneath the exit device bar mounting plate. Two Rivnuts were installed into the face of the door for securing the end cap mounting plate and strengthening the installation.

When the installation was completed, a few proximity cards were programmed in order to test the operation.

Choosing the proper keypad for an application will not only make the end user happier, but it should also provide years of no problem operation.
