System Power
The teleCARE IP system power supply shall be sourced from an external 24Vdc power supply, utilizing a
dedicated 2-wire power distribution bus. The external power requirement for teleCARE IP is 24Vdc, with
an acceptable range of 21.6Vdc to 26.4Vdc.
WARNING:
Use of any Power Supply other than those which are specified in this manual violates
the UL 2560 listing.
4.1
24Vdc / 3 Amp Power Supply (Standard)
The 24Vdc / 3 Amp Power Supply, Ascom part number APS5000, must be used with the teleCARE IP
system and can be purchased through Ascom.
The teleCARE IP Standard Power Supply shall be used to power the teleCARE IP system. This power
supply converts 115Vac / 60Hz input power to a 24Vdc / 3 Amp, Class 2 Rated regulated output.
There is a built-in charger to charge sealed lead acid batteries. The batteries provide the Secondary Power
to the teleCARE IP system in the event of mains AC power failure. There is an automatic switchover to the
batteries when input AC power fails. During switchover, there is zero voltage drop at the power output.
The power output fuse is rated at 15A/32Vdc.
WARNING:
• Do not use the Standard Power Supply for installations that require seismic considerations. Use the
24Vdc / 8 Amp Power Supply (Seismic) described in section 4.2 instead.
• Make certain that the AC circuit breaker is off before making any wiring connections between the
circuit breaker and the power supply.
• Always de-energize the power supply prior to servicing.
• When servicing, the AC mains circuit breaker should be in the off position and locked out to
prevent accidental activation.
• When necessary, always replace the fuse with the same type and rating (15A/32Vdc).
• This power supply is intended for indoor use only. Do not expose the unit to rain or moisture.
• After installation or servicing make sure that the cover is secured with the provided Key Lock.
4.1.1 Power Supply (Standard) Installation
The teleCARE IP Standard Power Supply is provided with an Installation Guide that is packaged with the
unit. The unit is intended for wall mounting at a fixed location. Follow the instructions in the Installation
Guide for mounting the power supply to a wall.
Note:
Power distribution is best organized with the power supply unit located as close as
possible to the rooms which it powers. This minimizes the voltage drop caused by the
length of the power supply wires and the load of the powered teleCARE IP system devices.
For setup and configuration, refer to the illustrations in the Installation Guide to identify the switch which
must be set for 24Vdc operation, and to identify the terminals for connecting the power supply board to
the batteries and teleCARE IP system.
