AUXILIARY OUTPUT AO WHEN SET TO MODE 002 CALL ACTIVATED
Fig.12 below shows the connection for auxiliary output AO when the AOM mode is set to 002. The auxiliary output AO will activate
once a call to an apartment has been made and will stay activated for the programmed auxiliary output time A1T.

The auxiliary output AO will activate from when a call is made
to an apartment and stay activated for the auxiliary output
time (A1T).

CONNECTING A SECONDARY DEVICE TO THE AUXILIARY OUTPUT AO
Since the auxiliary output AO is a transistor switched output (switched low output) it can be connected to a relay (e.g. an Art.506N).
This is particularly useful if a secondary device requires triggering. Fig.13 shows how to connect an Art.506N relay.
