DESCRIPTION
These power supplies are available with 10, 30 or 75
ampere outputs. Input voltage is selectable for 120, 208
or 240 vac. Refer to Section X or Table VI-5 (Section VI)
for power supply specifications.
EQ2100PSM
The EQ2100PSM Power Supply Monitor is used in
conjunction with an EQ21xxPS power supply and
backup batteries to provide power for the Eagle
Quantum system. Since the power supply monitor
resides on the communication loop (LON), any trouble
condition related to system power will immediately be
reported through the Local Control Unit. Status
conditions being monitored include power supply
failure, loss of AC power, loss of battery power, power
ground fault, AC voltage, DC voltage and battery
charging current levels.
The output of the power supply monitor is a status
message that is sent along the communication loop to
the gateway and logic controller in the Local Control
Unit (LCU). System response to the message is
determined at the time of configuration. The power
supply monitor supports ANSI/NFPA 72 Class A, Style 7
communication with the LCU.
Enclosure
The power supply monitor must be located in a
controlled non-hazardous area and must be mounted in
a suitable metallic nationally recognized test laboratory
(NRTL) labeled NEMA rated enclosure.
Fault Tolerant Network
Like other Eagle Quantum network devices, the power
supply monitor utilizes a unique patented technique for
detecting network wiring problems. This feature
minimizes the possibility of a communication breakdown
in the event of a wiring fault and can also serve as an
aid in troubleshooting.
A single open or short on the network will not affect
system communication between the field devices and
the LCU. System communication will continue until the
wiring problem can be repaired.
Status LEDs
The power supply monitor has three LEDs to provide a
visual indication of status conditions:
Green — On when power is applied to the device.
Red — On (flashing) indicates a trouble
condition.
Yellow — Used for factory diagnostic purposes.
EQ2200IDCGF
The available EQ2200IDCGF Initiating Device Circuit
Ground Fault Monitor responds to the presence of a
ground fault within the power circuitry of the Eagle
Quantum system. It provides a supervised dry contact
input and ground fault monitoring circuitry for indicating
a power supply trouble condition. It is intended for use
with a third party power supply.
II–8
“Power +” ground fault occurs if:
- Resistance of “Power +” to earth is <136K ohms.
- DC voltage is below +19.0 vdc (with 26 vdc supply voltage).
- Current >0.14 ma between “+” wire and earth.
“Power –” ground fault occurs if:
- Resistance of “Power –” to earth is <15K ohms.
- DC voltage is below –4.9 vdc (with 26 vdc supply voltage).
- Current >0.1 ma between “–” wire and earth.
“COM 1 / COM 2” ground fault occurs if:
- “LON B” wire resistance to earth is <4K ohms.
- “LON B” wire DC voltage is below –4.0 vdc.
- Current >1.0 ma between “LON B” wire and earth.
—OR—
- “LON A” wire resistance to earth is <2K ohms.
- “LON A” wire DC voltage is below +2.0 vdc.
- Current >1.0 ma between “LON A” wire and earth.
Note: Voltages are nominal and may vary slightly (voltages referenced to
earth).
Resistance/voltage levels between sides are different — same
readings indicate they are shorted together.
