UDACT-F Mounting Options
The UDACT-F may be mounted directly to the MS-9200 main circuit board or
remotely in an ABS-8RF or UBS-1F enclosure up to 6,000 feet (1,800 m) away from
the control panel. All power must be removed from the control panel before making
any connections to prevent circuit damage. The EIA-485 serial interface is connected
between the control panel and UDACT-F, using twisted shielded pair wire. Power
should be wired from the control panel's 24 VDC (nominal) filtered, nonresettable out-
put to TB1 on the UDACT-F (except when mounted in the MS-9200).
Mounting Inside the MS-9200 Enclosure
The MS-9200 must have firmware, with P/N 73580 or higher, installed to allow use of the UDACT-F. Remove all
power from the MS-9200 by disconnecting AC and batteries. Install the supplied standoffs (three nylon and one alu-
minum) in the appropriate holes located on the right side of the MS-9200 main circuit board, as illustrated in Figure
2-31, "UDACT-F Mounting to MS-9200," on page 47. Using the ribbon cable supplied with the UDACT-F, connect
J10 on the UDACT-F to J16 on the MS-9200. Note that the colored edge of the ribbon cable must be oriented toward
the top edge of the UDACT-F as illustrated in Figure 2-31. Carefully seat the UDACT-F on the nylon standoffs and
secure to the aluminum standoff with the supplied screw.
The EIA-485 circuit and 24 VDC power are provided directly from connector J16 of the MS-9200. Note that a 120
ohm EOL resistor is not required on the UDACT-F EIA-485 terminals when it is installed inside the MS-9200 cabi-
net. The EOL resistor is required at the last device (if any are installed) on the EIA-485 line external to the MS-9200
panel.
Programming
See "System Edit" on page 61, for information on programming the MS-9200 to function with the UDACT-F.
