The following figure illustrates an example of Central Station/Remote Station Reporting using a
UDACT-F (Universal Digital Alarm Communicator/Transmitter). The UDACT-F transmits system
status to UL listed Central Station receivers via the public switched telephone network. It may be
mounted inside the MS-9600 cabinet using the BRKT-9600 mounting bracket or remotely in a
UBS-1F or ABS-8RF enclosure.
Notes:
1. Ferrite cores (P/N FBD-1) are recommended for all applications. Install around wires inside
cabinets near terminal blocks.
2. Recommended wire is 12 AWG to 18 AWG (0.75 to 3.25 mm
2
) twisted, shielded pair.
3. If shielded wire is used, connect only one end of the shield.
4. Conduit is recommended for external wire runs (consult local building codes).
5. Connect ground wire from Earth Ground terminal on the UDACT-F to a solid building earth
ground. Conduit alone will not provide a reliable earth ground.
6. UDACT-F may be located up to 6,000 feet (1,800 m) away from the host control panel.
