6.4 Battery selection
The control panel power supply unit has been designed for work with lead
batteries or other batteries with a similar charging curve.
It is impermissible to connect to the alarm panel a fully discharged battery (with
voltage on unloaded terminals less than 11 V). To avoid damage to the
equipment, a fully discharged/never used battery should be precharged with the
use of a proper charger.

The batteries should be individually selected for each system. Presented below are some
examples of accumulator batteries energy balance as recommended by EN 50131-1:2005 for
the power supply units Type A, Grade 3. They assume that in the event of mains supply
failure the alarm system will have to work for 30 hours on emergency power supply, while
being able to remotely report the on the power supply trouble.
6.4.1 INTEGRA 24 – battery 7 Ah
The available 30 hr current for the 7 Ah battery is:
I
30h
= 7 Ah/30 h
≈
0.233 A (233 mA)
The average currents consumed by the components of the model alarm system based on the
INTEGRA 24 control panel:
•
mainboard, INTEGRA 24: 121 mA;
•
zones, NC: 4 x 5 mA;
•
keypad, INT-KLCD-GR: 17 mA;
•
partition keypad, INT-S-GR: 24 mA;
•
2 movement detectors, PIR: 2 x 10 mA;
•
2 magnetic detectors: 0 (require no power supply).

= 0.121 + 4 x 0.005 + 0.017 + 0.024 + 2 x 0.010 = 0.202 A (202 mA)
The summed average current consumed by the system is 202 mA, therefore it is lower than
the current that can be provided by the battery.
6.4.2 INTEGRA 32 – battery 7 Ah
The available 30 hr current for the 7 Ah battery is:
I
30h
= 7 Ah/30 h
≈
0.233 A (233 mA)
The average currents consumed by the components of the model alarm system based on the
INTEGRA 32 control panel:
•
mainboard, INTEGRA 32: 127 mA;
•
zones, NC: 8 x 5 mA;
•
keypad, INT-KLCD-GR: 17 mA;
•
partition keypad, INT-S-GR: 24 mA;
