4.7 P-600 Keypad Operation
Depress several keys. Each keystroke will generate a beep and an LED flash.
• When in the 8-Bit Burst mode (default), each keystroke sends data to the access panel.
• When in the 26-Bit Wiegand mode, you must press the # key after entering a PIN to
send data to the access panel.
4.8 P-600 Keypad Error Code (26-bit Wiegand Mode
ONLY)
The range for valid keypad entry codes is from 1 to 65534. When the keypad detects an
error condition the keypad automatically sends the binary code "1111 1111 1111 1111" -
in decimal this number is 65535. This code (binary 1111 1111 1111 1111, decimal 65535)
must be reserved for use as an error code. The Essex keypad sends this code to the
access panel when one of these three events occurs at the keypad.
1. The # key is pressed without any preceding digits.
2. Any number of 0s are pressed before the # key.
3. Entering the number 65535 or any number greater than 65535.
If an access panel is programmed to accept 65535 as a valid entry code any error
condition at the keypad will allow entry.
For security reasons Pyramid Associates recommends programming the code 65535 into
the access control system, assigning this code to an access group that never allows
access, and assigning this code the name "KEYPAD ERROR CODE" (or something similar).
