PRO-2000 Installation and Operation Manual

Hookup of AC Power and Batteries
The Power Supply provides a regulated 28 VDC to the PRO-2000 series and provides charge current to the
optional backup batteries. As the batteries are kept permanently charged, power is continuously provided
(Uninterruptible Power Supply or UPS). The power supply AC ratings are as follows:
120 V version: V = 120 VAC nominal, I = 1.5 A, frequency 60 Hz
220 V version: V = 220 VAC nominal, I = 0.8 A, frequency 50 Hz
LEDs are visible on the Power Supply indicating the functional status of the unit. As the Power Supply is
convection cooled, no fans or blowers are required. The transformer and power supply mount directly on the
mounting plate.
A built-in battery charger maintains the batteries at full capacity. After extended power outages, the charger
restores the batteries to full capacity. Short circuit, over-voltage, and brownout monitoring circuits protect all
powered components by switching to the batteries whenever a trouble condition exists in the power supply.
Alarm Supply
Power to the alarm devices in a system must be supplied from a separate battery backed-up Power Supply which
is "UL listed (ULC listed in Canada)" for fire protective signal system use.
AC Power Connection
CAUTION: Ensure all voltage sources are disconnected from the panels before installing or removing cards.
