Power supply

The power supply of the Extinguishing Control Computer 8010 is provided via the integrated power supply unit.
If necessary, an increased power requirement for external devices, e.g. caused by longer cable lengths, must
be compensated for with an external voltage supply via a separate power supply unit.
In case of an AC main power loss, the continuous voltage supply is ensured by the batteries. If the mains
voltage is not present after a delay time of 15 minutes (900s) a fault message is indicated. If the failure cause is
eliminated within this time no fault message will be generated.
At a total loss of the mains and battery voltage, a system start will be automatically carried out by the CPU if the
main voltage supply (not the battery voltage) is present again.
The power supply must be provided via an individual supply circuit with an external isolating unit,
e.g. miniature circuit breaker.

16.1.1 Emergency power supply

The built-in power supply unit is designed to control and charge two back-up batteries with each 12 V / 24 Ah. In
case of an AC mains power loss the control panel will be powered continuously by the back-up batteries.
Depending on the battery capacity a backup time of up to 72 hours can be realised. After that time the external
alarm devices must be still operable in an alarm condition. The activation of these devices must be ensured with
a low battery voltage of 21,2V DC.
For an emergency back-up time of 72 hours with the max. battery capacity a current of max. 230 mA is available
to power external loads.
First commissioning
New batteries must be recharged at least 24 hours before commissioning. The battery must be recharged for at
least 48 hours if the manufacturing date (see label) is about nine month ago.
Deep discharging
The power supply unit periodically monitors the charge of the batteries connected. If this battery test reveals a
battery voltage of below 10.0 V DC under load, battery trouble will be signalled. The battery charge is controlled
by means of a temperature-dependent resistor (NTC). As soon as the voltage of the batteries goes below 9.5V
the battery backup will get disconnected to protect the control panel. The control panel is no longer operational!
Eliminate the trouble condition of the mains power supply and turn/switch on the control panel. The connected
batteries will get charged automatically if the voltage of the batteries during the battery test without external load
is higher than 10.5V DC. A battery failure will be indicated if the voltage of the batteries does not exceed this
level. Discharged batteries have to be recharged with an external power supply or need to be replaced. This
Function can be enabled / disabled with the jumper on the basic module.
Exhausted batteries (off-load voltage U
Only the approved and recommended battery types may be used for supplying the Fire Alarm
Control Panels with backup power. Observe the information and technical specifications of the
battery manufacturer and the VdS-guidelines for deep discharged batteries.
