2-7 AC AND DC POWER CONNECTIONS
The control unit uses commercially- or end-user-provided AC power as the primary power
source, together with a 24 Vdc standby battery (when required by local codes and/or Authority
Having Jurisdiction [AHJ] requirements).
2-7.1 AC Power Connection
The primary AC power for the ARIES Control Unit is 120 Vac, 50/60 Hz, 3.2 A or
220/240 Vac, 50/60Hz, 1.6A. The default power configuration is 120 Vac and will require
resetting for 220/240 Vac operation. Configuration of primary AC power requires that the
power-selection switch on the side of the power supply be set correctly before the power
WARNING
Two different sources of power can be connected to the control unit. Disconnect
both sources of power and critical components such as control heads for special
extinguishing systems and addressable pilot relays controlling facility-power
shutoff before servicing the control unit. The control unit and associated
equipment may be damaged by connecting wiring while the control unit is
energized.
WARNING
Use caution when connecting power. High-voltage and AC-powered circuits are
present in the control unit. Be sure to adequately ground the control unit to
reduce the risk of electrical shock.
