3.0 Mounting

3.1 Considerations

• Ideally, one keypad should be located close to

the primary entry/exit door of the premises, and

the wire length must be within 305 m (1000 ft) of

the control panel.

• Do not mount outdoors [see Section 7.0

Commercial Fire Applications (DS7400Xi Series) for

commercial fire restrictions].

• The keypad should be mounted no higher than

shoulder height of the shortest person using the

system.

3.2 Instructions

1. Insert a small flat-head screwdriver in each slot at

the bottom of the base. Press up, and pull the

cover off.

2. Using the base as a template, mark the location of

the mounting holes (use any holes). Refer to

Figure 5 to select the mounting holes.

3. Provide an opening in the mounting surface for

the wiring.

4. Start the mounting screws.

Do not secure the base at this time.

4.0 Wiring

4.1 Control Panel to Keypad Wiring

Be sure all wiring is unpowered before

routing.

1. Route wiring from the control panel to the

keypads. Up to two keypads can be used on any

single 305 m (1000 ft) run of 0.8 mm (#22 AWG)

wire. Up to three keypads can be used on any

single 305 m (1000 ft) run of 1.2 mm (#18 AWG)

wire.

2. Bring the wiring through the wire entrance in the

keypad’s base and secure the base (Figure 5).

3. Connect the wiring to the keypad’s terminal strip

(Figure 6).

4. Place the keypad cover onto the base. While

feeding the excess wiring through the back of the

base, press the cover straight in until it latches.
