120/127 V    50/60 Hz (18 V    / 0.3 A adapter)

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 m

) of living space.

Up to 3 RF Signal Repeaters may be used with the SBT
for each system to extend the communications range.

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: 
0-40°C, 32-104°F, 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

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.
