Wiring

Use a four-wire flying lead connector to connect the
data and power connections between the
D1260/D1260B and the control panel. The
D1260/D1260B comes with a wiring assembly
consisting of four color-coded flying leads and a female
four-pin connector plug at one end. Wire resistance
must not exceed 14 Ω.
Excessive wire resistance degrades
keypad performance.
Use 18 AWG (1.2 mm) wire when connecting a
D1260/D1260B to a control panel.
To connect the D1260/D1260B to the control panel:
1. Power down the control panel.
Refer to Steps 1 and 2 in refer to Section 3.1.2
Mounting the Back Plate on page 10.
2. Connect the flying leads of the wiring assembly
(provided) to the wires from the control panel, as
shown in Figure 9.
