Chapter 2: Description
Overview
This chapter describes the Beacon 410’s external and internal components.
External Description
This section describes the housing and all external components of the Beacon 410. For
the purposes of this description, the housing door is considered the front of the monitor.
Housing
The Beacon 410’s fiberglass housing is weather- and corrosion-resistant. It is suitable for
installation where general purpose equipment is in use. The housing door is hinged on the
left side and is secured by two latches on the right side. The LCD display and status LEDs
are visible through windows in the housing door. Four mounting feet are attached to the
back of the housing (one at each corner). The mounting feet allow you to install the
housing to a vertical surface. Four conduit hubs on the bottom of the housing are for
external wiring connections.
CAUTION: To avoid electrical interference, do not route detector head and power wiring
through the same conduit hub.
Reset Switch
The reset switch is on the bottom of the housing in front of the buzzer. The reset switch
serves four functions:
• Resets the alarm circuits for “latched” alarms after an alarm 1, alarm 2, or alarm 3
condition passes.
You can set each channel for latched or self-resetting alarms in the Configuration
Menu. See “Viewing and Changing Channel Parameters” on page 35 for more
information.
• Silences the buzzer during an alarm 1, alarm 2, or alarm 3 condition if the buzzer
silence parameter in the Global Menu is set to CAN SILENCE BUZZER. See “Viewing
and Changing Global Parameters” on page 32 for more information on setting the
silence feature.
• Resets the strobe during an alarm 1, alarm 2, or alarm 3 condition if the strobe alarm
setting parameters are set to Resettable STROBE in the Configuration Menu. See
“Viewing and Changing Channel Parameters” on page 35 for more information on
setting the strobe alarm setting parameters.
• Displays and resets the minimum and maximum gas concentration values detected.
NOTE: Fail alarms cannot be reset or acknowledged with the reset switch. When a fail
condition passes, the Beacon 410 will automatically reset the fail alarm circuit.
