For the D9412G, D7412G, D7212G, D9124, D9412,
D9112, D7412, and D7212 Control Panels consult
Security System User’s Guide (P/N: 71-06141-000) and the
D9412G/D7412G Program Entry Guide (P/N: 47775).
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.
2.3
Audible Tones
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.
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 includes a wiring assembly
consisting of four color-coded flying leads and a female
four-pin connector plug at one end.
The maximum recommended wire run for each
D1255/D1255B is 2000 ft (610 m) with either 22 AWG
(0.8 mm) gauge or 18 AWG (1.2 mm) gauge wire.
