SCREEN
An auxiliary nominal 31V DC power supply is available to power ancillary devices requiring up to 30V
DC. Each auxiliary output can be programmed to cycle power during a system reset, or to keep its
power constant during a system reset.
Note: The auxiliary power supply output will be approximately 30-31V DC when the panel is running
from a mains supply. Or between 21.1V - 27V when running from the batteries in a mains failure
condition.
The maximum output current
for each circuit is
1.0A.
The Auxiliary Power outputs are protected by
2A
Fast blow
fuses.
It is suggested that additional Power Supply Units be installed to provide power for additional loads.
If additional power supply units are used they must be listed for use with Fire Alarm systems.
Battery: BAT+, BAT-
Terminals are supplied to connect and charge
standby batteries. The charging circuit has been
designed to charge 2 x 12V DC 12.0 Ah sealed
lead acid batteries. Batteries should be
connected in series as per the diagram.
