How to Install an Access Control Keypad System

Introduction to keypads  

There two general groups of Access Control Keypads, Stand Alone and Software Controlled.

The stand-alone access control keypads are programmable at the keypad by keying in operation and configuration data, passwords and users’ pin codes. Software controlled keypads are programmable mostly by proprietary software installed on a computer on the same network as the keypad. Each group includes 2 types of keypads: Keyboard only and those with keypads with RFID or Bio Readers.  

Access Control Keypads are included in Access Control Systems that include an electric lock (mostly magnetic or electric strike), a power supply to power the keypad and the electric lock and an exit button.

Selecting a keypad for your application

When selecting a keypad or an access control system that includes a keypad, you should consider:

    • The installation location environment

    • Keypad operation issues including the number of users and their skills

    • The skills of those who will maintain the keypad including its setup and programming 

Stand Alone Access Control Keypads  

Our stand alone keypads are loaded with features including 1000 user codes, RFID cards or KEYFOBS, unlocking capability of all doors, gates, and electrical locks, warning signals, temporary visitor codes and many more. They are easy to program and do not require an administrator with a master code or anyone having an extensive technical background.

Software Controlled Access Control Keypads

Our software controlled RFID access control keypads will control access to the same types of gates, doors and electrical locks as the stand alone keypads. But that is about where similarities end. Access controlled keypad/readers controlled by software provide a high degree of flexibility in their operational features such as: Entry and departure tracking records, shift setup for employees, easy access rights control and termination, remote monitoring via internet, access priority setup and much more.

Software controlled systems require someone familiar with setting up software programs and access control terms. Based on our experience, for flawless and successful usage of software controlled access control keypads, users must have an IT department or tech support capable of setting up menu driven software.      

General - Installation preparation

Wire Selection (Refer to Figure 1)

As in all cases involving electricity, the wire AWG must be selected to accommodate the peak current that will be conducted through it. In most cases low voltage wire 18AWG/2 (stranded) will be sufficient, assuming that the power supply is within 6 feet wire length of the electric lock. In situations where the power supply must be installed further from the lock, 16AWG/2 should be considered. The longer the wire, the higher is its resistance, thus dropping the voltage and power at the electric lock and keypad.

Selecting Keypad Mounting Location (Refer to figure 1 and 2)

When selecting the mounting location, the following environmental and application factors must be considered:

    • Height - Must be determined to allow a person of average height to reach the keypad to enter a code or reach the RDID card reader or KEYFOB. Typically, installation at a height of 5 to 5.5 feet will be sufficient.

    • Weather Exposure - If the keypad is installed at a spot exposed to weather elements, the keypad should meet a weather protection category of IP45 or better. Direct sunlight heating the keypad should be avoided or minimized. Direct sun combined with hot weather could produce a thermal runaway in the keypad electronic circuits causing irreversible damage.

    • Light - although all of our keypads are backlit, selecting a well-lit installation area will be helpful in the dark, provide a sense of security to the user and minimize vandalism.

    • Accessibility to power source - As we have indicated previously, it is advantageous to install the power supply as close as possible to the access control keypad set. In the event that a power supply must be installed remotely, wire must be selected that will accommodate the operational and technical requirements of the keypads and electric locks.

General Access Control Keypads Programming notes (Refer to figure 3)

In this paragraph, we cover most general and common programming notes for stand-alone RFID access control keypads. Software access control systems programming and setup are relevant to each model selected.

All of our stand-alone access control keypad are shipped with a default administrator code 0000.

The diagram below shows programming of the following parameters.

    • Entering programming mode for the first time with code 0000 (factory default). Amber LED at center will be ON and steady, indicating the keypad is in programming mode.
    • Changing the factory default master code from 0000 to 3289, e.g. (Master codes could be 4 to 8 digits).
    • Recording an RFID card or KEYFOB at location 001.  
    • Recording User PIN code (4-8 digits) at location 002 to activate Relay Output 1.
    • Recording a combination of RFID card or KEYFOB and PIN codes. In this example, the user PIN code is 6123. To gain access the user will be required to enter both PIN and show the RFID to the reader/keypad. This PIN code is relevant only for the user with the corresponding RFID card or KEYFOB.
    • Recording a combination of RFID card or KEYFOB and a common user PIN code. Common user codes are programmed into location 003 and 004 (for keypads with a 2nd output). The common user code programmed in this example is 1357. To unlock, the user will have to show the RFID reader his card or KEYFOB and then enter the common code.
