Panel-Specific Information
Below is an internal installation of UDACT-2 with an AM2020/AFP1010 using an MPS-24B main power supply:
A.6 NFS2-3030 (UL 864 10th), NFS-3030 (UL 8th)
A.6.1 General
The UDACT-2 is capable of reporting up to 2,040 ACS points when used with the NFS2-3030/NFS-3030. For the UDACT-2 to correctly
report a point to the Central Station, both the FACP and the UDACT-2 must have each point programmed as the same function type
(refer to “Zone and Point Assignments” on page 26). If UDACT-2 point does not match the panel point in function, the point will default
to fire alarm and a fire alarm signal will be transmitted to the Central Station.
A.6.2 Mounting
The UDACT-2 may be mounted in the control panel enclosure or be mounted remotely using an ABS-8RB, UBS-1B, or UBS-1R enclo-
sure. The unit must be placed within the same room and within 20 feet (6.1 meters) of the panel. Wiring must be enclosed in conduit. For
mounting instructions see "Remote Installation" on page 17 or "Internal Installation" on page 13.
A.6.3 Wiring
Connections
Refer to Figures A.14 through A.16.
Connect the communication line between the EIA-485 terminal block on the CPU2-3030/CPU-3030 and EIA-485+ and EIA-485- termi-
nals on the UDACT-2, being certain to observe polarity.
If the UDACT-2 is the only or last device connected to the EIA-485, set SW1 DIP 1:4 to ON to enable the UDACT-2’s 120 ohm termi-
nating resistor.
Connect the Ground Wire (PN 71073, provided) from the UDACT-2
EARTH
terminal on TB1 to the CHS-4 Chassis or to a solid building
earth ground.
Connect 24 VDC filtered, regulated power from the CPU2-3030/CPU-3030 or AMPS-24/E (Main Power Supply) to +24V and -24V on
TB1 on the UDACT-2.
