2.0 Digital Keypad

The D1255/D1255B Keypad features a digital keypad for accessing the menus, entering user passcodes and executing system commands in the control panel. As you press keys, the D1255/D1255B emits a muted beep tone (refer to Section 2.3 Audible Tones) to indicate that the entry is accepted. The keypad lights when you press keys, and remains lit for 20 sec.

When entering a passcode, press keys within 15 sec of each other. If 15 sec elapse between keystrokes, the entire entry clears, and you must start over. The keypad also "times out" on other functions if you wait 15 sec or more between key presses.

The D1255/D1255B Keypad has a built-in speaker that produces several distinct warning tones. The speaker volume is changed by adjusting the potentiometer (refer to Item 5 in Figure 2 on page 4). Turn the potentiometer clockwise to increase volume and counterclockwise to decrease volume. The speaker volume also changes as you adjust the brightness of the display. Refer to Command 49 “Dim Display” in the Security System User’s Guide (P/N: 71-06141-000) for more information. You cannot connect external annunciation devices to the D1255/D1255B. The tones in Table 2 are silenced by entering a programmed passcode with the appropriate authority.
