Alarm Verification Enable (91)
Alarm verification works only on zones programmed as 2-wire smoke detector zones (i.e. zones 1 and 3). After
detecting an alarm, the panel removes power from two-wire smoke zones for 6 seconds, resetting all 2-wire smoke
detectors. Power is reapplied and a 12 second retard period allows detectors to stabilize. During the retard/reset
period of 18 seconds, subsequent alarms by the same initiating zone are ignored. An alarm detected on any other
2-wire detector zone during the retard period will cause immediate verified alarms. A subsequent alarm on the
initiating zone occurring within the confirmation time will cause a verified alarm. Note: Mixing devices on zones
designated as 2-wire smoke zones is not recommended. The communicator will not transmit a signal to the Cen-
tral Station signifying that alarm verification is in progress.
During the alarm verification period, access to other modes of operation is prevented.
Factory Default is no verification which is an entry of '0'. Entering '1' enables verification. Alarm Verification is
ignored if the 411UDAC is configured for nonlatching Slave Communicator operation or Test Mode.
Note: consult local Authority Having Jurisdiction (AHJ) prior to altering this address.
Silence Inhibit Notification Appliance Circuit (92)
Setting address 92 to '1' prevents the silencing or resetting of the Notification Appliance Circuit for one minute
following an alarm. The factory default setting is '0' for no silence inhibit.
Autosilence Notification Appliance Circuit (93)
The Notification Appliance Circuit may be autosilenced after a programmed time interval between 5 and 30
minutes. Enter '1' for 5 minute autosilence; '2' for 10 minutes; '3' for 15 minutes; '4' for 20 minutes; '5' for 25
minutes; '6' for 30 minutes. The factory default is '0' for no autosilence.
Restoral Method (94)
Note: Restoral Method refers to the communication of Restoral Events to a Central Station. It has no effect on the
actual input circuit restoral itself.
• Typical Restoral Method - ‘0’ entry programs the panel to transmit each input circuit restoral, as it occurs, to
the Central Station. In Slave Mode, this means that as soon as an input restores, the communicator will
immediately transmit the Restoral Event to the Central Station. In Stand-alone Mode, the restoral of inputs
programmed as Autoresettable Supervisory will also cause the communicator to transmit a Restoral Event
immediately. All other input types in Stand-alone Mode are latching and their restoral will not communicate a
Restoral Event until the Reset Switch is pressed.
• Conditional Restoral Method #1 - ‘1’ entry programs the panel to transmit each input circuit restoral, as it
occurs, to the Central Station. In Slave Mode, this means that as soon as an input restores, the communicator
will immediately transmit the Restoral Event to the Central Station. In Stand-alone Mode, the restoral of
inputs programmed as Autoresettable Supervisory will also cause the communicator to transmit a Restoral
Event immediately. All other input types in Stand-alone Mode are latching and the communication of their
Restoral Events are dependent upon an after-reset condition.
