EQ211xPS, EQ213xPS and EQ217xPS Power Supplies
Refer to Table 3-3A for Power Supply ratings.
Backup Battery
Refer to Table 3-4 or 3-5 to calculate the minimum
size of the backup battery (in amp hours). Select a
sealed lead-acid battery with an adequate amp hour
rating.
NOTe
Connect two batteries in series for 24 volts. Be sure
that the battery enclosure is adequately ventilated.
Battery Charger
Use the following formula to calculate the minimum
battery charger size:
CAUTION!
Care should be
taken when considering the
final voltage at the device during AC power loss.
With loss of AC power, the device voltage will
drop over time as the batteries lose their charge.
If extended periods of AC power loss are to be
expected, either consider a heavier wire gauge
or specify batteries with higher amp-hour ratings.
EQP2120PS(–B) Power Supplies
The EQP2120PS(–B) Power Supplies are used in pairs
where the primary source of input supply is connected to
one and the secondary source is connected to the other.
A maximum of eight power supplies operated in parallel
can be connected to each input supply. Both the primary
and secondary sets must be individually capable of
operating the system without the other supply. The
secondary source is required to be continuously powered.
The use of these supplies is based upon acceptance
of the local AHJ of the secure supply system that
provides the secondary supply. These supplies must
be used in a redundant configuration, where one bank
of supplies are fed from the primary source and the
other bank from the secondary supply. Both primary
and secondary supplies shall be continuously
available and both rated for a minimum 100% of load.
Refer to Table 3-3B for power supply ratings.
IMPORTANT
The eQP2120PS(–B) Power Supplies provide
eQP System devices with power from input
supply 120 to 220 V ac. Use of this power supply
does not provide the source of the secondary
supply such as secondary source batteries, their
supervision or charging, or UPS. Per NFPA
72-2002 requirements, such power supply
related requirements must be separately
provided for and be accepted by the local
Authority Having Jurisdiction (AHJ).
