Alarm Management

The In-Reach IR-7104 from
MRV Communications is a four-slot modular, expandable, high-density alarm and
control concentrator engineered to address the needs of telecommunications
network service providers and corporate enterprise facilities.
Space-Efficient, Expandable Design The space-efficient design
of the IR-7104 requires only 1U of rack height. It is designed to support a
family of modules that provide a variety of alarm input and control output
functions.
The IR-7104's expandable chassis can be populated with up to
4 high density modules, each of which can process alarm state information from
32 wet- or dry-contact closure alarm points. A single IR-7104 can manage up to
128 alarm points.
The IR-7104 is ideally suited for wireless cellular
sites, public utilities, manufacturing facilities and data centers that employ
enclosure door alarms, environmental alarms, power, pressure and fluid alarms.
Distributed Architecture The distributed architecture of the
IR-7104 solution requires an In-Reach 9000 or LX-4000S series master unit be
connected upstream via an RJ-45/RS-232 serial interface. The master unit handles
all IP/SNMP/TL-1 protocol processing, master alarm status and alarm management
functions.
The benefit of the distributed master-slave architecture is
that it enables the IR/LX master and IR-7104 slave units to efficiently manage
thousands of alarm points using a single IP address.
Further, master
units provide secure remote console management and remote power management of
all critical network elements.
Alarm Input Option The alarm
input module contains 32 alarm points that support dry contact or isolated wet
contact circuits without the need for hardware configuration changes. The alarm
circuits detect the following:
Normally open (dry contact) Normally
closed (wet contact) Wet contacts with applied voltages in the range of 3.5V
to 75 VDC Closure to V+ TTL level Closure to 0 (GND)
Control
Output Option 8 Form C relay control output points are available on the
Control Output option module for enabling a wide range of devices, including
backup power generator systems, HVAC systems, emergency lighting systems,
control valves, sirens and other devices. Normally open and normally closed
contacts are available on each Control Output module.
Analog
Option The Analog Option of the IR-7104 delivers 8, 4-20 ma loop inputs
for supporting a wide range of analog alarm sensor devices. It will accept
standard 4-20 ma sensors such as battery, temperature, humidity, pressure and
storage tanks.
Event HorizonT - Fault Management System Event
Horizon is state-of-the-art fault management system software (FMS) that provides
NOC managers with the tools they need to quickly identify and resolve alarm
events and fault conditions. Engineered to work in concert with our In-Reach
series hardware, it provides maximum efficiency and rapid return on investment.
