Installation Instructions Please Read Before Installing Overview The System Bridging Timeclock (SBT) bridges two RadioRA systems, providing a total of 64 Zone Controls and 24 Master Controls. The SBT also provides an RS-232 interface, contact closure inputs, and an astro-
nomic time clock. Each SBT covers approximately 2500 square ft.
(232 m2) of living space. Up to 3 RF Signal Repeaters may be used with the SBT for each system to extend the communications range. Important Notes Codes: Install in accordance with all local and national electrical codes. Power: Use only the adapter provided by Lutron with the SBT. Caution - Using an adapter not rated for the following specifications could damage the SBT and possibly overheat the adapter. Input: 120/127 V 50/60Hz Output: 18 V / 0.3 A Class 2 Environment: Ambient operating temperature:
0-40C, 32-104F, 0-90% humidity, non-condensing. Indoor use only. Cleaning: To clean, wipe with a clean damp cloth. DO NOT use any chemical solutions. Do not paint the SBT. Mounting: DO NOT ground the SBT. DO NOT mount the SBT in a metal enclosure. RF Device Placement: Master Controls and Zone Controls that are to be controlled by the SBT must be located within 30 ft. (9 m) of the SBT or an RF Signal Repeater. Setup: The SBT will not function until it is addressed and programmed. See the System Bridging Timeclock Setup and Programming Guide.

Find a suitable location for the SBT. Place the SBT in a convenient and accessible location. See RF Coverage Diagrams on page 5. 2. Mount the SBT. Mount SBT to wall using the appropriate mounting hardware provided (see Mounting Diagram). Orient the processors anten-
na for optimal performance. For most installations, the antenna should be oriented vertically. Note:
DO NOT ground the SBT. DO NOT mount the SBT in a metal enclosure. 3. Apply power to the SBT. Verify LED lights when powered Plug in power cord and adapter Mounting Diagram Wall Anchors Mounting Screw Mounting Screw Optional Mounting Screw Included:
Drywall Anchors (3) Masonry Anchors (3) Mounting Screws (3) Mounting Screws (3) 2 configuration. 4. Configure the SBT. Use the SBT display to set 5. Connect Serial Link (if applicable). Connect a standard DB9 male connector to the RS-232 con-
nector on the SBT for communications with other equipment. 6. Connect external input closures (optional). The SBT accepts three low-voltage dry contact clo-
sures. Connect wiring for closures to input terminal block if desired (see Wiring Diagrampage 3). When using the input closures:
Verify compatibility of external devices. The input closures are intended for use with devices that provide outputs in the form of dry contact closure outputs. The input closures may be used with ground-referenced, solid-state outputs if the out-
puts have an on-state saturation voltage of less than 2 V and an off-state leakage of less than 50 A. Dry contact or solid-state outputs must be capable of switching 18 V at 10 mA. The outputs must stay in the closed or open states for at least 40 msec in order to be recognized by the SBT. If there is any question as to whether the contact closure device is compatible with these specifica-
tions, contact the manufacturer of that device. Dimensions Front View
