You must observe local wiring regulations. Do not run SELV and LV cables in the same enclosure
without adequate insulation between them.
Mains Connection
Each Cooper CFDAU30 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.
Batteries
The Cooper CFDAU30 requires 2 number 12V 3.2AH sealed lead acid batteries to provide backup
power in the event of mains failure as defined in BS5839pt8 for 24 hours standby and 30 minutes
operation.
For 72hour standby and 1 hour operation 2 number 12V 17AH batteries are required, these will need to
be fitted in an external battery enclosure, the monitored charger in the Cooper CFDAU30 is capable of
charging and monitoring these batteries.
Safety Information:
Sealed Lead acid batteries contain sulphuric acid which can cause burns if exposed to
the skin, the low internal resistance of these batteries means large currents will flow if
they are accidentally short circuited, causing burns and a risk of fire- exercise caution
when handling batteries.
Power Up Procedure:
Always apply mains power before connecting batteries, do not commission Cooper
CFDAU30 on batteries, as the high inrush current required by the power supply may
rupture the battery fuse.
Always connect the Positive (Red +) terminal first.
Power Down Procedure
Disconnect the batteries before removing the mains power; always remove the negative
(Black – terminal) first.
