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.  
2.1  
Keypad Function Keys  
The D1255/D1255B has five function keys. These keys

D1255/D1255B enclosure cover using a small flat-  
bladed screwdriver.  
3. Lift the D1255/D1255B cover away from the base  
as the tabs are pushed back.  
4. Set the address switches (refer to Section 3.3.1  
Setting the DIP Switches on page 5).  
5. Connect the flying leads of the wiring assembly  
(provided) to the wires from the control panel  
(Table 3).  
The D1255/D1255B Keypad can be mounted using the  
following optional packages:

and damage internal components.  
6. Turn the keypad over and plug in the wiring  
connector through the opening in the back of the  
enclosure base.  
7. Mount the keypad base in the desired location.  
8. Secure the keypad in place from inside the  
enclosure base by inserting screws in the mounting  
holes.  
9. Replace the cover by aligning and inserting the top  
two tabs of the enclosure cover into the top two tab  
slots of the enclosure base.  
10. Hold the top edges of the enclosure cover and base  
in position.  
11. Push the tabs inward.  
Do not mount the D1255/D1255B in wet  
or moist locations.  
3.2  
Wiring  
Data and power connections between the control panel  
and the D1255/D1255B require a four-wire flying lead.  
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.  
12. Press the enclosure and cover together until the
