Secondary Power
Secondary Power for the teleCARE IP system shall be provided by two lead acid Batteries installed in the
primary power supply. The batteries are each rated for 12Vdc, 7 ampere hours (AH) and can be
purchased through an electrical supplier such as Graybar.
WARNING:
• Batteries must be secured within the power supply cabinet as described in section 4.2.1.
• The lead acid Batteries must comply with UL 2054.
• When installing or servicing the lead acid Batteries, follow the instructions for installation of the
appropriate power supply and observe all WARNINGS and CAUTIONS described in sections 4.1 and
4.2.
Use the following table to determine the total Standby and Active load in amperes hours for Secondary
Power, when used with the teleCARE IP Standard Power Supply for standard installation and the HPFF8
Power Supply for seismic installations.

teleCARE IP Power Supply Wiring
It is important to use the correct wire sizes and to consider the length of the 24Vdc power supply wires.
The minimum acceptable wire size of the 24Vdc bus is 18 AWG (1mm).
For the stub wiring between the 24Vdc bus and the control module wire size 18 AWG (1mm) must be
used.
Warning:
Incorrect wire size can result in dangerous overheating of the wires!
Caution:
Excessive 24Vdc bus length can result in unacceptable voltage drop! The lowest
acceptable voltage at any point in the 24Vdc distribution is 21.6Vdc.
