Honeywell NOTIFIER UDACT-2 Instruction Manual page 40

Panel-Specific Information
Below is an internal installation of a UDACT-2 with an NFS-640:
A.4 NCA-2 (UL 864 10th), NCA (UL 8th)
A.4.1 General
The UDACT-2 is capable of reporting a maximum of 2040 ACS points when used with the NCA or NCA-2. For the UDACT-2 to cor-
rectly report a point to the Central Station, both the NCA-2/NCA and the UDACT-2 must have each point programmed as the same func-
tion type (refer to "Zone and Point Assignments" on page 26). If a UDACT-2 point does not match the NCA-2/NCA point in function,
the point will default to fire alarm and a fire alarm signal will be transmitted to the Central Station.
A.4.2 Mounting
If the UDACT-2 is not mounted in the same cabinet that contains the NCA or NCA-2, it must be mounted remotely in an ABS-8RB,
UBS-1B, or UBS-1R. The unit must be placed within the same room and within 20 feet (6.1 meters) of the network annunciator. Wiring
must be enclosed in conduit.
If the NCA or NCA-2 is contained in a CAB-4 Series cabinet, then the UDACT-2 may be mounted to a CHS-4/CHS-4MB chassis
assembly within that cabinet.
A.4.3 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.8 through A.11.
Connect the communication line between the EIA-485 terminal block TB3 on the NCA or TB7 on the NCA-2 and TB2 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 TB2 to the chassis or to a solid building earth
ground.
Connect 24VDC filtered, non-resettable power from TB1 on the NCA or TB6 on the NCA-2 to TB1 +24V and -24V terminals on the
UDACT-2. Power can also be supplied from TB3 AUX on an AMPS-24/E when using an NCA-2.
