The NX-534E listen-in module sends a continuous indicator tone to the central station
until the access code is received or the maximum number of attempts is exhausted. When
a code is received, the indicator tone is silenced.

The NX-534E listen-in module waits for the access code to match. The reset [#] key may
be used during PIN entry to clear the PIN buffer. If the access code does not match after a
set number of attempts, the system returns to stand-by mode and waits for a new trip. If
the code is validated, the system silences the siren and starts a two-way session.
Control levels
Levels of the modes may be changed at any time by pressing * followed by the level number you
wish to access on a touch-tone telephone. If no key is pressed for 3 seconds on the telephone, then the
buffer is automatically cleared. Press * on the telephone twice to return to the beginning.
•If a new alarm in the same partition is activated during a two-way session, the session timer can be
