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 6000 feet 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 24VDC (nominal) filtered, nonresettable
output to TB1 on the UDACT-F (except when mounted in the MS-
9200).
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. Position J10 located on the back of the UDACT-F over connector
J16 which is located center right on the main MS-9200 circuit board, and carefully
connect. Secure the UDACT-F to the aluminum standoff with the screw provided.
The EIA-485 circuit and 24VDC power are provided directly from connector J16 of
the MS-9200. Note: A 120 ohm EOL resistor is not required on the UDACT-F EIA-
485 terminals when it is installed inside the MS-9200 cabinet. The EOL resistor is required
at the last device on the EIA-485 line external to the MS-9200 panel.
