Description

The 49-8104RK Standby Battery is designed for use with a gas monitoring controller
capable of running from 24 VDC such as the RKI Instruments, Inc. Beacon 200, Beacon
410, or Beacon 800 controller. It can provide temporary power to a controller if primary
AC power is lost. The standby battery consists of the ho using, two batteries (shipped
uninstalled), three connection wires (shipped in a small bag), and wire nuts for wiring
connections. The figure below shows the batteries and wires installed.

Housing

The standby battery’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. 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. A cond uit hub on the top of the housing is for
external wiring connections. A weathe r-resistant vent on the upper left side prevents
buildup of hydrogen in the housing if it is vented by the batteries.

Batteries

Two lead acid 12 VDC, 12 AH batteries are shipped with the housing but are not installed.
The batteries must be installed into the housing and connected with a wire jumper s o th at
they produce 24 VDC. T wo wires must be connected to the batteries to allow connection to
the positive and negative of the standby battery. The ends of these wires are covered with
insulating shrink tubing to prevent shorting during shipment. These pi eces of shrink
tubing will have to be removed during installation of the standby battery (see “Wiring the
Standby Battery to a Controller” on page 7 ).

Wire Nuts

Three wire nuts are provided with the standby battery for wiring connections. The wire
nuts are shipped in the standby battery packaged in a small plastic bag. Only two wiring
connections will have to be made to the standby battery (see “Wiring the Standby Battery
to a Controller” on page 7), so one of the wire nuts is provided as an extra in case one is
lost or damaged.
