Front door rfid

This article is Out of date. Please update this article and remove this template!

Our RFID reader takes 125kHz passive rfid tags (“EM compatible tags”). I bought it from Amazon. The product listing has an original copy of the instructions, which I’ve tried to improve upon below.

Programming

To manage the reader, you enter management mode, do some management things, then save your changes. Here’s how:

Management Password: A board member should know this.

User Password: A board member should know this.

Enter management mode

Push the following: * [management password] # The thing will beep at ya

Exit management mode

Push *

Note: Changes must be saved before one minute of inactivity elapses, or else management mode will be exited without saving.

Add one card

Do the following: push 1, scan the new card, enter the 3 digit code for the card, push #

N.B. The three digit code identifies a user’s card in the system. This code can be used to deactivate users’ cards when they leave the space. 3 digit codes must fall between 001 and 800, inclusive. Implicit in this is, if SSHC gets more than 800 members, we’ll need a new access control system.

Add many cards

I’m pretty sure it’s possible to add several cards with an auto-incrementing code, but I need to verify this. TBD.

Revoke a card

This can be done in two ways: Push 2, read the card to be revoked, push # or Push 2, enter the 3 digit code of the card to be revoked, push #

Revoke all cards

Nuclear option? Push 2, push 0000, push #

Select open mode

This reader supports three conditions by which it will open the door, using a valid card and/or the User Password defined above. I guess there’s only one user password.

• Card only: Push 3, push 00, push #
• Card and password: Push 3, push 01, push #
• Card or password: Push 3, push 02, push #

Select open time

This is the duration in seconds for which the door will be unlocked following the successful scanning of a card or entry of a code.

Push 4, enter number of seconds, push #

N.b. The number of seconds must be a 2 digit number, 01-99 inclusive.

Theftproof alert

The card reader / keypad has a little switch that senses if it’s being pulled off of the wall and I guess you can set it up such that it sets off an alarm if this happens. Not real sure what the instruction sheet is trying to say here:

• Push 6, 00, # to close the output of alert to prevent from disassembling. This is the default mode.
• Push 6, 01, # to trigger the output of alert to prevent from disassembling

Modify management password

Push 0, enter new password, push #, enter new password again, push #

The new password must be a 4-8 digit number

Modify the user password

Push 5, enter new password, push #, enter new password again, push #

I think this can only be a 4 digit number.
