Wiring the Beacon 800 Gas Monitor
This section describes procedures to connect the AC power source, DC power source,
external alarms, and detector heads. See Figure 5 for a general wiring diagram of all
external wiring to the Beacon 800.
NOTE: All connections to building electrical systems must be installed in accordance
with local requirements and must be installed by qualified personnel.
WARNING: Make all connections to the Beacon 800 before you plug in or turn on
the AC or DC power source. Before you make any wiring adjustments,
always verify that all power sources are not live.
Routing Wiring Into the Beacon 800 Housing
Wiring must be brought into the housing through one of the four factory-installed conduit
hubs on the bottom of the housing.
Do not
drill into the Beacon 800 housing for any reason. Drilling the Beacon 200 housing
and routing wiring through holes not factory drilled will void the warranty
and could result
in:
• Damage to internal components from the drilling process.
• Moisture damage to internal components from poorly sealed holes.
• Unpredictable Beacon 800 behavior due to EMI/RFI interference caused by wires
routed across the PCBs.
• Possible shorting of Beacon 800 components due to wires routed across the PCBs.
Accessing the Terminal Strips
Perform the following procedure to gain access to the AC and controller terminal strips,
which are located behind the display board.
1. Turn off or unplug all incoming power to the Beacon 800 at the power source end.
2. Open the housing door, then place the power switch in the OFF position.
3. Loosen the two captive thumbscrews (on the right side of the display board) that
secure the board to the standoffs, until the screws are disengaged from the standoffs.
4. Gently pull the right side of the display board out toward the housing door. (The
standoffs under the left side of the display board are hinged, which allows the display
board to move in this manner.)
