NFS2-640 (UL 864 10th), NFS-320/SYS (UL 864 10th), NFS-640 (UL 8th)
Below is an internal installation of a UDACT-2 with an AFP-300/AFP-400:
A.3 NFS2-640 (UL 864 10th), NFS-320/SYS (UL 864 10th), NFS-640 (UL 8th)
A.3.1 General
The UDACT-2 is capable of reporting a maximum of 99 zones, or 636 ACS points when used with the NFS2-640 or NFS-640. It has a
maximum of 99 zones or 318 ACS points when used with the NFS-320/SYS. For the UDACT-2 to correctly report a point to the Central
Station, both the panel and the UDACT-2 must have each point programmed as the same function type (refer to "Zone and Point Assign-
ments" on page 26). If a 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.3.2 Mounting
If the UDACT-2 is not mounted within the cabinet that contains the NFS2-640, NFS-640, or NFS-320/SYS, then it must be mounted
remotely in an ABS-8RB, UBS-1B, or UBS-1R enclosure. 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. This is the recommended installation for use with the NFS2-640.
• If the UDACT-2 is mounted within the cabinet that contains an NFS-640, then it may be mounted to another chassis within the
CAB-3/4 backbox.
• within the cabinet that contains an NFS-320, then it must be mounted to the NFS-320 chassis and programmed before installing
the KDM2-R2 keypad.
• within the cabinet that contains the NFS2-640 or NFS-320SYS, then it may be mounted to the panel chassis or another chassis
within the CAB-3/4 backbox. If mounted on the panel chassis, the UDACT-2 must be mounted in the rear position of the fourth
column with no other option boards in front.
A.3.3 Wiring
CAUTION:
!
REMOVE ALL POWER FROM THE CONTROL PANEL BY DISCONNECTING AC AND BATTERIES BEFORE MAKING
ANY CONNECTIONS TO PREVENT PERSONAL AND/OR CIRCUIT DAMAGE.
Connections
Refer to Figures A.4 through A.7.
To the NFS2-640 and NFS-320
Connect the communication line between the EIA-485 terminal block TB11 on the CPU2-640 and TB2 terminals EIA-485+ and EIA-
485- 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.
