Installation Guide
teleCARE IP
• 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.
• 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.
4.2.1 Power Supply (Seismic) Installation
The HPFF8 Power Supply is provided with an Installation Manual that is packaged with the unit. The unit
is intended for wall mounting at a fixed location. Follow the instructions for Backbox Mounting of a
Standard Cabinet provided in the Installation Manual.
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, use the illustrations provided in the HPFF8 Installation Manual to identify the
locations of jumpers and terminals. Follow the instructions in this manual for connecting the power
supply board to the batteries and teleCARE IP system
Inspect the Control Circuit Board (Figure 1.1 in the HPFF8 Installation Manual) to ensure that the Charger
Disable Jumper (J1) and Ground Fault Disable Jumper (J2) are both installed.
Install the Reference Resistor to the REF+ and REF- terminals on TB3. Use either a 3.9K or 4.7k ohm, ¼
watt resistor as the Reference Resistor.
Caution:
The same value resistor used for the Reference Resistor must be used as the End of
Line (EOL) resistor for the teleCARE IP system power bus.
Before connecting and powering the teleCARE IP system, refer to sections 4.4 and 4.5 in this manual.
Install the EOL resistor at the last NIRC3 unit on the teleCARE IP power bus.
Caution:
Measure the output voltage at the [+BAT-] and [+DC-] terminals before connecting
the batteries or teleCARE IP system. Improper high voltage will damage the connected
devices.
Caution:
Always de-energize the power supply unit prior to connecting the batteries and
teleCARE IP system.
Caution:
Maintain vertical separation where power-limited (i.e., DC power to teleCARE IP) and
non-power-limited circuits (i.e., mains AC and battery wiring connections to the Control
Circuit Board) appear to cross.
Before connecting and powering the Secondary Power Batteries, the batteries must be secured within the
HPFF8 cabinet enclosure using the Seismic Installation Kit. Follow the instructions provided with
Honeywell model SEISKIT-COMMENC.
Connect the AC mains power (115Vac/60Hz) to the TB1 terminals marked [L1, Ground, L2] on the HPFF8
Power Supply Board.
Apply mains AC power. Measure and confirm 24Vdc at the [+BAT-] and [1L1/1L2 through 4L1/4L2 and
A+/A-] terminals.
De-energize the power supply, connect the batteries and teleCARE IP system (to the 4L1/4L2) terminals.
