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
