MSA4H/V: 4 Button Wall Switch V1.0
MSA4H (horizontal)
MSA4V (vertical)

Description

The MSA4H/V is designed to work with the Imperial system's
MAMA home automation engine. Each button can be
programmed to control a single output, multiple outputs, or
macros. The wall switch can provide on/off control of lights,
sprinklers or macros, set lights to a fixed dimming level, or
open motorized shutters to a preset height.
All wall switches are driven by the V32 Main Controller's 4 wire
low-voltage Multibus. This means that the high voltage wiring is
not connected directly to the switch as in regular electrical
systems. Since the wall switches use low-voltage bus
communication, they can be installed anywhere including wet
areas or outdoors (avoiding direct sunlight, or exposure to rain/
snow).
Up to 510 wall switches can be programmed to control one
output, as opposed to a maximum of 3 switches or 1
dimmer knob in regular electrical systems.

Overview

1) Output and macro control buttons
2) Button lights

4) Multibus feedback LEDs
5) Label trays
6) 4-wire Multibus connection
NOTE: For more detailed installation and programming
instructions, refer to the Imperial System Guide.
