MCP CONSTRUCTION
The MCP enclosure is designed for surface mounting
and is rated NEMA 1 for indoor use. It is constructed of
18 Gauge steel, painted red and kept closed by a steel
door with a key-lock. All operator interface switches and
indicators are located behind the locked cover. The
enclosure is large enough to house two 12 AH 12 Vdc
batteries for backup power supply. Battery Enclosures
are available for larger capacity batteries. A trim-ring is
available for flush mounting.
REMOTE HAZARD UNIT (RHU)
RHU POWER SUPPLY
The Power Supply Unit in the RHU is the same unit as in
the Main Control Panel.
RHU DISPLAY-CONTROL MODULE
Remote Hazard Units are available either with or without
a Display-Control Module. When used, as shown in Fig-
ure 4, the RHU Display-Control Module is similar to that
of the MCP with the exception of the Menu Control but-
tons, which are provided only on the MCP. RHU Displays
can be programmed to operate either in local or global
mode.

RHU INPUT AND OUTPUT CIRCUITS
Each RHU is also a Single Hazard Panel and is similar to
the Main Control Panel being provided with the same
Input and Output Circuits (with the exception of the three
System Relays). The Optional Relay Board (ORB) can
also be mounted to the RHU.
RHU CONSTRUCTION
When using the optional Display-Control Module, the
RHU Enclosure is similar to that of the MCP. If this option
