General
The Universal Digital Alarm Communicator Transmitter
(UDACT) is designed for use on the Notifier NFS-320, NFS2-
640, NFS2-3030, NFS-640 and NFS-3030 Fire Alarm Control
Panels and on the NCA-2 and NCA Network Control Annunci-
ator. When used in conjunction with the NCA-2 network con-
trol annunciators the UDACT can report the status of all control
panels on NOTI•FIRE•NET™. The UDACT transmits system
status to UL listed Central Station Receivers via the public
switched telephone network.
NOTE: The UDACT can also be used with legacy panels. Please
refer to the UDACT manual for more information.
The UDACT is compact in size and may be mounted externally
in a separate cabinet. EIA-485 annunciator communications
bus and regulated 24-volt connections are required.
The UDACT is capable of transmitting the status of software
zones (Alarm and Trouble), System Trouble, Panel Off-Normal,
Supervisory, Bell Trouble, Low Battery, and AC Fail. The
UDACT is capable of transmitting all of the zone and point sta-
tus associated with each panel.
When the UDACT is used with the , NFS-3030, NFS2-3030,
and NCA-2 it is capable of reporting up to 2,040 points.
Reporting may be in the form of points or zones (refer to the
UDACT manual for specific reporting parameters). The first
568 points transmitted may be programmed for a variety of
types, including fire, waterflow, supervisory, etc. Remaining
points transmitted are for fire alarm only.
NOTE: Descriptions regarding point capacity, listed above, are for
receivers which receive in Ademco Contact ID format. See chart
on page 2 for compatible receivers.
