Connecting Power Sources and Outputs Installation
3.15 Connecting Power Sources and Outputs
3.15.1 Overview
Complete all mounting procedures and check all wiring before applying power. Electrical
connections include the following:
• Primary power source. +24VDC, delivered through AMPS-24/AMPS-24E main power
supply. If AMPS-24/E is mounted in a separate cabinet, power-supply wiring must be in
conduit (for cabinet placement information see Section 3.4 “Laying Out Equipment in Cabinet
and Chassis” and the AMPS-24/E manual.
• Secondary power source. +24 VDC from batteries, installed in the control panel (or in an
optional battery cabinet). Secondary (battery) power is required to support the system during
loss of primary power.
• External power sources. +24VDC auxiliary power supplies that are UL/ULC-listed for fire
protective service.
• Accessory power for peripheral devices. TB6 on the CPU draws power from primary,
secondary and external sources to supply a maximum of 1.0 amp of +24 VDC power to
devices within the same enclosure as the CPU. If those devices have outputs, the outputs must
be power-limited.
!
WARNING:
Remove all power sources to equipment while connecting electrical components. Leave the
external, main power breaker OFF until installation of the entire system is complete.
!
WARNING:
Several sources of power can be connected to the control panel. Before servicing the control panel,
disconnect all sources of input power including the battery. While energized, the control panel and
associated equipment can be damaged by removing and/or inserting cards, modules, or
interconnecting cables.
NOTE: The CPU ships with an insulator to prevents its lithium battery from discharging. To
preserve the battery, this insulator should be left in place as long as possible before applying AC
power. Some installers may find it convenient to remove the insulator before mounting all
equipment.
NOTE: If using multiple power supplies with one set of batteries, refer to main power supply
manual for connection requirements.

WARNING:
Auxiliary power supply connections to ICM-4RK/ICE-4 must
come from a power supply whose
battery terminals are tied back to those on the main power supply. Failure to do so will cause panel
circuit trouble at the control panel and possible equipment damage.
