Backup Batteries
The optional Battery Enclosure contains two rechargeable 12 V batteries wired in series to give a nominal 24 VDC supply.
The batteries can be either 12 Ah or 27 Ah and they are overload-protected by a 20 A fast acting inline cartridge fuse.
A new set of 12 / 27 Ah batteries should supply 22.5 V at 20 A for up to 16.75 / 32 minutes respectively, depending on the
connected load. However, you should be aware that all batteries deteriorate over time, and Honeywell recommend that you
check and replace them regularly to ensure optimum performance in an emergency.
Note
: Always switch the Battery Isolator switch to
Off
before carrying out any work on the battery circuit, and ensure it is
On
when work is completed.
The 12V monobloc batteries are Valve-Regulated Lead Acid (VRLA) Absorbed Glass Mat (AGM) batteries that:
•
Are optimized for discharge (buffer) times of up to 20 hours @ 3 A.
•
Have a 5 year design life in float operation in temperature controlled environments.
•
Have VRLA AGM and gas recombination technology with 99% internal recombination.
•
Are non-spillable and maintenance free.
•
Are non-hazardous when packaged for air/sea/rail/road transportation.
•
Are 100% recyclable.
