1. The maximum battery capacities which can be charged according to BFPSA
recommendations are - 34Ah
2. Any battery which cannot be contained in the c.i.e. enclosure must be located in
an enclosure adjacent to the c.i.e.
3. The approved Premier AL panel comprises internally mounted 12Ah batteries.

19.1Auxiliary Supply
An auxiliary supply is available to power external field equipment from the panel.
This is nominally rated at 28V (24V for Premier AL Global Network Repeater) but
varies during mains failed conditions. The maximum load is 500mA, the output is
fused and fuse failure will be indicated as a panel fault.
The auxiliary supply terminals are labelled 28V and 0V.
Note: If equipment draws current from the auxiliary supply during the mains failed
condition this must be included in the battery capacity calculations.
19.2Use Of Auxiliary Outputs
Warning: The volt-free auxiliary relay contacts must not be used to directly switch
any voltage which exceeds 30VDC.
Auxiliary changeover contacts are provided which operate on fire and fault
conditions. There are two sets of auxiliary fire contacts. These switch on any fire
condition and can be programmed to operate on remote evacuate (full remote
evacuate mode) or to remain inactive on remote evacuate (partial remote evacuate
mode). Programming the remote evacuate mode is described in section 24.16. The
configuration of the relay contacts is shown in Figure 9.

Figure 9 – Auxiliary fire contact connection details
The single set of auxiliary fault contacts operate on any panel fault condition. This
output is failsafe and is active in a system fault, or if the system suffers failure of all
power supplies. The configuration of the relay contacts is shown in Figure 10.
