the bottom center of the controller,
can be used to install the Tracer
ZN.520 zone controller in a
communication network.
Warning! If the Service push button
is held down for more than 15
seconds, the Tracer ZN.520 zone
controller will uninstall itself from
the ICS communication network and
shut down all unit operation. This
mode is indicated by the red Service

The green LED normally indicates
whether or not the controller is

or wink mode. Table 6 describes the

Note
1
: During manual output test,
certain diagnostics make the status
LED light in a two-blink pattern. If a
two-blink pattern remains after an
attempt to clear diagnostics, the
diagnostic condition is still present
and may affect the manual output
test. The diagnostic must then be
cleared using another method. Refer
to 'Resetting diagnostic'.
Note²: the Wink feature allows you to
identify a controller. By sending a
request from Rover service tool, you
can request the controller to wink
(blink on and off as a notification that
the controller received the signal).
The green LED blinks (1/4 second on,
1/4 second off for 10 seconds) during
Wink mode.
