Standby Battery Requirements

For door controllers, the battery voltage

should match the lock output voltage.

Now that you know the total continuous current

requirement of the door controller plus readers, locks

and ancillaries, you should multiply this figure by the

number of hours standby needed.

In the enclosure supplied, there is room for two 12 V

7 Ah batteries. If this does not provide sufficient

backup, the batteries must be located outside the case

or the controller mounted in a larger case.

Note:

A door controller with a continuous current of 2 A will

require at least a 4 Ah battery to provide 2 hours cover

(2 A x 2 hours = 4 Ah).

The Ah rating of a battery is usually

determined when discharged over a 10

or 20 hour period. If a fully charged

battery is discharged over a shorter

period than this, as in the example above,

it will last for less time than its rating

suggests. You should consult the battery

manufacturer's correction factor charts to

determine a more accurate figure. than

expected.

Using an External Charger

In order that a fully discharged battery can recover to

a fully charged state within 24 hours, you should

consider using an external charger when using more

than a 7 Ah battery. Use the wiring shown below.

Note:

The auxiliary battery charger output must not exceed 2

VDC over K2200 battery output.
