Introduction

Voice Alarm (VA) systems are the quickest way to evacuate the public & staff from a building.

Following fire detection, automated messages control the flow of people in stairwells and corridors

allowing an orderly evacuation without panic. These messages are supplemented by spoken messages

from the fire service or management suite confirming the validity and need to leave the building.

This positive confirmation speeds evacuation and avoids the "false alarm" mentality reducing the risk of

death from fire.

CFDAU30 is a new Voice alarm system from Cooper Fire

An innovation which combines the Cooper analogue addressable Fire detection and alarm functionality

with very sophisticated cause and effect program with the latest voice alarm address technology.

Up to 20 CFDAU30 per loop with build in amplifier can be connected to any Cooper addressable Fire

Panel.

CFDAU30 has build in isolator and can be hard or soft addressed by the Cooper addressable panels

The CFDAU30 delivers clear, intelligible voice alarm messages which ensures reliable and constant life

safety protection for both people and property.

It is well documented that only 13% of people react to bells, whilst 70% react to a voice message.

Suitability

Voice Al

arm systems are recommended for all public buildings and multi story buildings over four floors

by BS5588.

In public buildings it's not possible to fire drill the public, as they visit the premises infrequently, so

systems such as Voice alarms save valuable time in evacuating the building.

The use of phased messages in multi-story buildings prevents over-crowding in stairwells and at exits,

preventing secondary injuries. In phased evacuation, the floor in fire receives the evacuate message,

and the floor above & below receive an alert message, preparing them for evacuation.

In more complex scenarios the use of multiple alert and evacuate messages can be beneficial, essages

telling the evacuees they are going the right way, and messages asking people to make way for people

leaving evacuated areas. These additional messages can dramatically speed up the evacuation

especially in malls and large airport environments.

Product Overview

Cooper has been developed a VA system to replace talking sounders in many voice alarm applications,

and is available in several forms. The CFDAU30 is a complete VA system in a single wall mount box

which is complete with messages, fire interface, dual 30W monitored amplifiers, power supply,

monitored battery charger and the ability to connect non monitored paging and music directly. Up to 20

CFDAU30 per loop with build in amplifier can be connected to any Cooper addressable Fire Panel.

CFDAU30 has build in isolator and can be hard or soft addressed by the Cooper addressable panels

The CFDAU30 delivers clear, intelligible voice alarm messages which ensures reliable and constant life

safety protection for both people and property.

It is well documented that only 13% of people react to bells, whilst 70% react to a voice message.

The CFDAU30 has been developed to draw the minimum of current in standby conditions and mutes the

music when the AC supply fails, the unit then draws 60mA quiescent current allowing the use of 3.2AH

commodity SLA batteries for full compliance with BS5839 part 8.

The speaker lines are monitored using a low current DC system, which is continuous, and works with

the music playing. Faults reported are open, short and earth faults. Each speaker fitted to Cooper

CFDAU30 must have a DC blocking capacitor fitted. The use of DC monitoring allows all cable types

(MICC and soft skin) to be used with the system.

Music sources can be plugged directly into the DAU, and the level of this can be set using a remote DC

volume control. When used with a paging microphone, the music ducks and restores gently after paging.

Priorities

The Cooper CFDAU30 has six fixed priorities for the inputs as follows:-

1. Fire Microphone, this is the highest priority input on the system, designed to be used by

the controlling officer.

2. Message Generator, this has three messages, all messages latch until reset from either

the front panel recessed button, or from the cancel button on the fire microphone or by the

RESET input from the Fire alarm input. Messages are prioritised in the following order:

a. EVAC- Triggered from the fire alarm interface or from the fireman’s microphone, top

priority message.

b. ALERT- Triggered from the fire alarm interface or from the fireman’s microphone,

second priority message.

c. TEST- Triggered from the front panel or from the fireman’s microphone, this is the

lowest priority message.

3. Page Input, this is the fifth priority input, designed for non-emergency functions such as

reception paging.

4. Music Input, this is the lowest priority input and automatically selected when no other input

is exerting a priority, if not used turn the level control on the front panel fully anticlockwise.

Operation

The Cooper CFDAU30 is fully automatic in operation; the only user controls available once the unit has

been commissioned are the front panel Reset and Test buttons. Pressing the test button will broadcast

the test message to the speaker circuits and latch until the Reset button is pressed.

The Cooper CFDAU30 has fully compliant fault monitoring when correctly installed and commissioned, if

any status indicators are illuminated YELLOW (except the Message ACCESS Led) call service to

investigate the cause of the fault, this should be indicating a Sounder or Voice alarm fault on the Fire

Alarm Panel.

Maintenance.

It is a requirement of BS5839pt8 that a maintenance agreement be in place for Voice Alarm systems,

the maintenance schedule should be as follows.

Weekly: Broadcast the test message to all zones, and check speaker operation, microphones

should be checked for operation if fitted, record results in the site log.

Monthly: Trigger the fire alarm system when the building is empty and check the Evacuate

message broadcasts, record results in the site log.

Quarterly: Engineer Call to check system operation.

Yearly: Engineer Call to check system operation and check Battery Health.

5 Yearly: Engineer Call to check system operation and replace the batteries.

WARNING

NO USER SERVICABLE PARTS

Each exchange unit requires a 3A spur, returning to a breaker clearly marked Voice Alarm
DO NOT TURN OFF. If the units are distributed around a site it is essential all units are on the

same mains phase, as they are classified TEN 230V, powering from different phases can

mean a 440V potential can be present in a unit during a major fault incident.

Anti-static handling guidelines

Make sure that electro-static handling precautions are taken immediately before handling

PCBs and other static sensitive components

Before handling any static-sensitive items, operators should get rid of any electrostatic charge

by touching a sound safety earth, such as a radiator. Always handle PCBs by their sides and

avoid touching any components. PCBs should be stored in a clean, dry place that is free from

vibration, dust and excessive heat.

Storing the PCBs in a suitable cardboard box will also guard them against mechanical

damage.
