3.4.2 Battery Pack BU-5
The BU-5 can be installed underneath the 905K or beside it. The BU-5
uses the same type of enclosure as the 905K and is mounted in the same
way. The BU-5 has a “cable tail” which plugs into the 905K. The input
wiring is then connected to a socket on the BU-5.
The lid of the BU-5 can be rotated to suit installation.
A second BU-5 can be connected to the first in a similar manner. The
input wiring for the 905K is then connected to the socket on the second
BU-5.
All plugs and connectors should be waterproofed with waterproofing
tape.
Check the label on the back of the BU-5 to make sure that it has been factory-set to 9V (model
BU-5-2).
The BU-5 takes six alkaline AA batteries - such as Duracell MX1500 or Eveready E91. Do not
use rechargeable batteries in the BU-5 as their self discharge life is short. The temperature rating
of the BU-5 depends on the battery type - for alkaline batteries, this is typically 15 to 120 degF
(-10 to 50 degC). Special “industrial” batteries, such as Eveready EN91, have a wider
temperature range, -20 to 130 degF (-30 to 55 degC).
