Today I got the a 433 Mhz Keypad that can do RFID.
Runs on 3AAA batteries.
Six screws hold it shut and a connector connects it to between the keypad and the electronics.
There is a tamper switch in the back that emits a code when it separates from the wall.
It can be programmed with 5 RFID cards and each card produces its own code.
There are 4 buttons that produces codes as well, a perimeter alarm, away alarm, disarm, and doorbell.
After 30 seconds, the device goes in to a dormant mode. To take it out of dormant mode press any key to wake it up.
After it wakes up you can start sending codes.
To send RFID press * then scan the RFID FOB.
To send either the codes take it out of dormant, press the code (default is 1 2 3 4) then press one of the function buttons and it will send a code.
