Metreau Keypads Instruction Manual
AxLink Wiring
In AxLink mode, Metreau keypads use a standard four-pin captive-wire AxLink connector for power and data.
CAUTION:
If using power from AxLink, disconnect the wiring from the control system before wiring the Metreau keypad. Do not
connect power to the keypads until the wiring is complete.

NOTE:
Before touching the device, discharge the static electricity from your body by touching a grounded metal object.

AxLink Wiring Guidelines
Metreau keypads require 12 VDC power to operate properly. The necessary power is supplied via the AxLink cable. The maximum
AxLink wiring distance is determined by power consumption, supplied voltage, and the wire gauge used for the cable.
The following table lists wire sizes and the maximum lengths allowable based on the maximum power consumption rating of 170
mA.
The maximum wiring lengths for using AxLink power are based on a minimum of 13.5 volts available.
Preparing Captive Wires
You will need a wire stripper, and flat-blade screwdriver to prepare and connect the captive wires.
1.
Strip 0.25 inch (6.35 mm) of wire insulation off all wires.
2.
Insert each wire into the appropriate opening on the connector according to the wiring diagrams and connector types
described in this section.
3.
Turn the flat-head screws clockwise to secure the wires in the connector.
NOTE:
Do not over-torque the screws; doing so can bend the seating pins and damage the connector.
