Wiring guidelines
Metreau keypads require 12 VDC power to operate properly. The necessary power is
supplied via the AxLink or SWT cable. The maximum 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.
supplied via the AxLink or SWT cable. The maximum 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. If the distance is greater than what is listed in the table, consult
the Metreau Keypads Operation/Reference Guide for wiring with external power
sources.

AxLink Status LED
The AxLink Status LED (located next to the AxLink connector), lights to indicate
AxLink power/data status (see Operation / Reference Guide for details).
If the LED is on and not flashing, disconnect the AxLink connector and recheck all
AxLink connections. Then, reconnect the AxLink connector to the panel and verify
the LED is flashing once per second.
