What is difference between fault and alarm?

As nouns the difference between alarm and fault is that alarm is alert, alarm while fault is a defect; something that detracts from perfection.

What is fault alarm?

An alarm is a persistent indication of a fault that clears only when the triggering condition has been resolved. A current list of problems occurring on the network component is often kept in the form of an active alarm list such as is defined in RFC 3877, the Alarm MIB.

What does fault mean on smoke alarm?

A ground fault is defined as the unwanted grounding of one or more conducting wires. This can occur in several places. It can happen inside the fire alarm control unit enclosure, metal raceway, metal junction box, or any other location in which conducting wires and an earth ground source are close in proximity.

What is a trip alarm?

A basic trip alarm system is essentially a simple booby trap. The alarm signaling device will be tethered to a length of trip wire. When the wire is pulled hard enough (presumably by someone tripping over it), it activates the device which alerts you to the presence of an intruder.

What are the different types of fault in telecom network?

There are two types of network fault management: active and passive. Active fault management uses various tools, such as ping or TCP/UDP port checks, to continually query devices and determine their status.

What is network fault?

A network fault can be as obvious as a failed network port. It can also present less obvious symptoms such as an inexplicably slow network, intermittent loss of network connectivity on computer systems and poor voice quality on telephones. Adjustment to configuration of network switches, routers and firewalls.

How do you clear a ground fault on a smoke detector?

First, disconnect all alarm circuit wires from the main control panel. Each circuit will have two, three or four conductor wires. Disconnect all the wires. This should reset the panel’s ground fault indicator.

What causes ground fault on fire alarm system?

A ground fault occurs when one or more electrical components are short circuited to a ground potential. In a fire alarm system, this can occur when an exposed wire or alarm component touches a metal “grounded” object, such as a junction box, ceiling grid, or any other metal object located in a building structure.

What does a trip wire do?

A tripwire is a passive triggering mechanism. Typically, a wire or cord is attached to some device for detecting or reacting to physical movement.

What are the disadvantages of fault?

Cons of Faults Fault lines can be prone to volcanic eruptions and or earthquakes. Fault openings can release magma to the surface. Lava flows are common along the African Rift Valley, e.g the Mt Nyirangongo (DRC) eruption in 2002. Fault slips can cause earthquakes big or small depending on the size of movement.

What does ground fault mean on alarm system?

GROUND FAULT (also may display as “EARTH FAULT”): A condition in which an alarm system references a structure’s common ground plane. This can be caused by a wire to an INPUT or OUTPUT DEVICE that is “pinched” or been abraded so as to contact the metal backbox (or conduit).

What do the alarm trip points mean on a relay?

Some alarm trips also offer the option of setting the relay to trip if there is an input fault (such as a broken sensor), or to alert that there is a problem with the alarm trip itself (Figure 4). The following examples describe how alarm trip points might be set for a dual output limit alarm trip.

What is the purpose of a limit alarm trip?

A limit alarm trip can trigger the response needed to maintain normal, and safe, operations. A limit alarm trip monitors a process signal (such as one representing temperature, pressure, level or flow) and compares it against a preset limit.

When does a differential alarm trip on a window alarm?

A differential alarm trips when the difference between two input signals, such as two RTD temperature sensors, exceeds a specific value. The Window Alarm is activated when the process variable is outside of the low/high trip point ranges (Figure 8).
