4.3 Secondary Power
Secondary Power for the teleCARE IP system shall be provided by two teleCARE IP 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 teleCARE IP Batteries shall be lead acid and must comply with UL 2054.
• When installing or servicing the teleCARE IP 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.

4.4 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 gauge (1mmØ) (0.8mm²).
For the stub wiring between the 24Vdc bus and the control module wire size 18 gauge (1mmØ)
(0.8mm²) 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.
