Connecting the Power Supply to AC Power
Installation
2.3 Connecting the Power Supply to AC Power
TB1 (KAPS-24) - Primary AC power source
– 120 VAC, 50/60 Hz, 5.0 A (ACPS-610E uses
220-240 VAC, 50/60 Hz, 2.5 A) from line voltage source.
The ACPS-610 requires connection to a separate dedicated AC branch circuit. Follow these
guidelines when connecting the AC branch circuit:
• Label the branch circuit “Fire Alarm”.
• Connect the branch circuit to the line side of the main power feed of the protected premises.
• Do not power other non fire alarm equipment from the fire alarm branch circuit.
• Run the AC branch circuit wire continuously, without any disconnect devices, from the
power source to the power supply.
• Overcurrent protection for the AC branch circuit must comply with Article 760 of the
National Electrical Codes, as well as local codes.
• Use 12–14 AWG (3.31 mm
2
– 2.08 mm
2
) wire with 600 VAC insulation for the AC branch
circuit.
Connect primary power as follows:
1.Turn off the circuit breaker at the main power
distribution panel.
2.Open the plastic insulating cover on TB1 on the
KAPS-24 (see Figure 2.9).
3.Connect the earth ground terminal (TB1-
EARTH
) to a solid earth ground (a metallic, cold
water pipe may be suitable in some installations).
This connection is vital to maintaining the power
supply's immunity to unwanted transients
generated by lightning and electrostatic discharge.
4.Connect the primary power neutral line to
terminal marked
NEUTRAL
and the primary power
AC line to terminal marked
HOT
.
5.Close the plastic insulating cover over TB1.
!
WARNING: Risk of electrical shock!
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: Risk of equipment damage!
Several sources of power can be connected to the control panel and/or power supply. 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.
