OVERVIEW
The Bus Booster is used on the GR 2400 System when the distance between wall stations and
a relay panel cause voltage drop. The Bus Booster provides up to 0.8 amp at 12 volts DC to wall
stations over the GR 2400 bus. While the data can travel 4,000 ft., the power to a wall station
needs to be fed with a relay panel or a Bus Booster.
FEATURES
•  Ability to provide up to 0.8 amp at 12 volts DC to the system bus

Insufficient Power
Normally, up to three bus-powered
devices may be powered across
1000 feet of Cat. 5 cable. This
ensures that the power supplied
by the Master LCP is sufficient for
each device.

DEVICE
Specifying a Bus Booster allows
you to add more devices without
dropping voltage, because it
provides additional power to the bus.
