Ground Stud
The ground stud is used for connecting earth ground to the Beacon 800. The ground stud
is factory wired to the GND terminal on the AC terminal strip. The ground stud is located in
the lower right corner of the main board.
Terminal Strips
The Beacon 800 includes four terminal strips for external wiring connections. See “Wiring
the Beacon 800 Gas Monitor” on page 12 for detailed wiring procedures.
Transmitter Terminal Strips
Two transmitter terminal strips are mounted to the bottom left corner of the main circuit
board (see Figure 1). These two 12-point terminal strips facilitate wiring connections to the
detector heads. The bottom terminal strip is for channels 1 through 4; the top terminal strip
is for channels 5 through 8.
Alarm Terminal Strips
Four alarm terminal strips are to the right of the transmitter terminal strips (see Figure 1).
These four 12-point terminal strips facilitate wiring connections to external alarm devices
(horn, strobe, etc.). The bottom row of alarm terminals is for alarm 1 connections; the top
row of alarm terminals is for alarm 2 connection.
NOTE: The alarm terminal strips provide external alarm connections controlled by
individual channels. The Beacon 800 also provides common alarm terminals on
the controller terminal strip. The common alarm terminals are controlled by all
active channels.
Controller Terminal Strip
The 19-point controller terminal strip is to the right of the alarm terminal strips (see Figure
1). The controller terminal strip facilitates various internal and external wiring connections.
Table 3 lists the function of each terminal.
