2.3 Battery Installation

The diagram opposite shows the

recommended location and orientation

for the 7AH batteries within the panel.

For battery sizes greater than 7AH, the

batteries must be installed in a separate

enclosure suitable for fire protection use

with wiring connected to the panel

through rigid conduit.

2.4 Wiring Installation

Refer to Manual 680-014 for further information.

2.5 Battery Standby Calculation Chart

Use the following charts and associated notes to calculate the size of the batteries required to ensure operation

of the installation in the event of AC Mains power failure.

Use the detector manufacturers' technical information to calculate the load on the loop for both the quiescent condition and fire alarm

condition for all loop devices. By default, a maximum of 5 detector / call point LED indicators will be turned on in a fire alarm condition. (This

number can be changed via the PC Programming Tool).

The calculated loop loading must be multiplied by a factor of 1.25 to calculate the actual current draw from the batteries. This is to take into

account voltage conversion and conversion efficiency in generating the supply for the loop.

Refer to separate data sheets for the additional modules that can be powered from the panel AUX Output to determine the AUX loading

currents. For example, the modules can include Modem, Sounder Splitter, Routing Interface, etc. The sum of all these additional currents

should be entered in these fields.

The alarm load should be doubled to allow for changes in battery efficiency for loads in excess of the recommended C/20 discharge rate.

The total load calculated should be multiplied by a de-rating factor of 1.25 to allow for changes in battery efficiency over time. The above

calculation is in accordance with the recommendations in BS5839-1: 2002.
