Mounting Options
The UDACT-F may be mounted in the control panel or mounted 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 FACP 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 con-
trol panel's 24 VDC (nominal) filtered, nonresettable output to TB1 on the UDACT-F
(except when mounted in the MS-9200).

Panel Mounting
2.2.1 MS-9200
The MS-9200 must have firmware with a Part Number of 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 aluminum standoff) in the appropriate holes located on the right side of the MS-9200 main circuit board as
illustrated in Figure 2-2. 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 2-2. 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 on the EIA-485 line, external to the MS-9200.
