UDACT Instruction Manual — P/N 50050:M 12/18/2009 103
Appendix H: AM2020/AFP1010 (UL 8th)
H.1 General
The UDACT is capable of reporting up to 2,040 points when used with the AM2020/AFP1010
(1,980 Addressable devices plus 60 zones or 1,800 Addressable devices plus 240 zones) The first
568 points can be programmed using the Type Mode feature (refer to "Type Mode" on page 52). All
points greater than 568 can be transmitted only as fire alarm points. For the UDACT to report a
supervisory point to the central station, both the FACP and the UDACT must have the point
programmed as supervisory. Failure to program the panel or UDACT correctly will result in a fire
alarm signal being transmitted to the central station.
H.2 Mounting
The UDACT may be mounted in the AM2020/AFP1010 control panel enclosure or be mounted
remotely using an ABS-8RB or UBS-1 enclosure placed within 6000 feet (1828.8 meters) of the
control panel.
For mounting instructions see "Remote Installation" on page 22 or "Internal Installation" on page
18.
H.3 Wiring
H.3.1 Connections
Refer to Figure H.1 and Figure H.2 on page 105.
Connect the communication line between the EIA-485 terminal block on the AM2020/AFP1010
and TB-1 terminals 3 and 4 on the UDACT, being certain to observe polarity.
If no other devices are connected to the EIA-485, install a 120 ohm EOL resistor across UDACT
TB1 terminals 3 and 4.
Connect the
Ground Wire (PN 71073, provided) from the UDACT EARTH terminal on TB3 to the
CHS-4 Chassis or to a solid building earth ground.
Connect 24 VDC filtered, regulated power from the MPS-24A or MPS-24B (Main Power Supply)
to TB1 terminals 1 and 2 on the UDACT.
NOTE: The UDACT does not support voice and burglary options when used with the
AM2020/AFP1010. Refer to the AM2020/AFP1010 Installation Manual for additional restrictions
and more information.
