Take Control Remotely

Remote Annunciator Panels are dedicated-purpose transponders that support

fire alarm system status information. They are typically used when the host fire

alarm control panel is located away from the area where those responding to a

fire situation need status information. Remote annunciators allow firefighters to

access information and take control of the fire detection system. When equipped

with an optional remote microphone and emergency voice/alarm communications

system control, operators can play prerecorded emergency messages, tones,

or make live broadcasts into selected areas or globally across the system.

Annunciators can include remote master firefighter telephones. These allow

annunciator users to connect with remote firefighter phone call-in requests and

enable firefighter phone callers to be connected to each other. Although intended

for use in assisting fire responders, these phones are also helpful during system

setup and testing.

Features

• Remote microphone and operator interface:Users can access the emergency

voice/alarm communications system from the annunciator.

• Easy-to-use operator interface:Remote Annunciators feature a 2 x 40-character LCD.

An optional color touchscreen display makes accessing system reports and responding

to emergencies simple and intuitive. An easy-to-use, color touch screen interface is

also available.

• Remote master telephone:First responders can communicate directly with the

firefighter telephone system.

• Future-proof design: Simplex control units can be easily upgraded to the latest

technology.

ABB REU 523 secondary relay Overvoltage unit

Overvoltage unit

When the voltage values exceed the set start value of low-set stage U>, the overvoltage

unit will start to deliver a start signal after a ~60 ms’ start time. When the set operate time

at definite-time characteristic or the calculated operate time at inverse definite mini

mum time (IDMT) characteristic elapses, the overvoltage unit will deliver a trip signal.

When the voltage values exceed the set start value of high-set stage U>>, the overvoltage

unit will start to deliver a start signal after a ~50 ms’ start time. When the set operate time

at definite-time characteristic or the calculated operate time at IDMT characteristic

elapses, the overvoltage unit will deliver a trip signal.

The low-set and the high-set stage of the overvoltage unit can be given either a defi

nite-time or an IDMT characteristic. At IDMT characteristic, two time/voltage curve

groups, A and B, are available.

It is possible to block the tripping of an over voltage stage by applying an external binary

input signal to the relay.

The high-set stage can be set out of operation. This state will be indicated by dashes on the

LCD and by “999” when the set start value is read via serial communication.

ABB The over and undervoltage relay REU 523 is a secondary relay

Application

The over and undervoltage relay REU 523 is a secondary relay which is connected to the

voltage transformers of the object to be protected. The over and the undervoltage unit

continuously measure the fundamental wave of the phase-to-phase voltages of the object.

On detection of a fault, the relay will start, trip the circuit breaker, provide alarms, record

fault data, etc., in accordance with the application and the configured relay functions.

The overvoltage unit includes low-set stage U> and high-set stage U>> and the undervolt

age unit low-set stage U< and high-set stage U<<. The high-set undervoltage stage can

alternatively be set to evaluate the positive phase-sequence voltage. In addition, the high

set undervoltage stage can be configured to evaluate only one instead of three phase-to

phase voltages.

The protection functions are independent of each other and have their own setting groups

and data recordings. The over and undervoltage functions use conventional voltage trans

former measurement.

An output contact matrix allows start or trip signals from the protection stages to be

routed to the desired output contact.

Design

The relay includes a high-set and low-set overvoltage unit, a high-set and low-set und

ervoltage unit and a circuit-breaker failure protection unit. Further, the relay includes an

HMI module, a self-supervision system and a disturbance recorder.

ABB REU 523 Combined Overvoltage and Undervoltage Relay

The REU 523 is intended for overvoltage and undervoltage protection in medium

voltage distribution networks but can also be used for protection of generators,

motors and transformers.

The REU 523 continuously evaluates the fundamental wave of the three phase-to

phase voltages. In addition, the high-set undervoltage stage can be configured to

evaluate either only one instead of three phase-to-phase voltages or the

positive-phase-sequence voltage.

The REU 523 is based on a microprocessor environment. A self-supervision system

continuously monitors the operation of the electronics and the software.

The HMI includes a Liquid Crystal Display (LCD) which makes the local use of the

relay safe and easy.

Local control of the relay can be carried out using a portable computer connected to

the front connector and remote control via the rear connector connected to the

distribution automation system through the serial interface and the fibre-optic bus.
