Fire Alarm Control Panel IQ8Control C / M
6.1.4 Emergency power supply
In case of loss of the mains voltage the control panel will be powered without a interruption by the connected
battery. Depending on the capacity of the battery 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
still possible with a minimum battery voltage of 10.5 V DC.
First Commissioning
New batteries must be charged at least 24 hours before operation. If the date of manufacturing is dated back
about more than 9 month a battery charge time of min. 48 hours is required.
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
9.5 V DC 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 10.5 V DC. A battery failure will be indicated if the voltage of the batteries does not exceed this
level. Discharged batteries must either be recharged with an external power supply or replaced, including in pairs
if necessary. This Function can be enabled / disabled with the jumper BR2 on the power supply module.
§
The battery manufacturer and VdS Schadenverhütung GmbH guidelines on the total discharge of
batteries must also be observed.
Exhausted batteries (off-load voltage U
Observe the information and technical specifications of the battery manufacturer and the
VdS-guidelines for deep charged batteries.
The fire alarm control panel might also issue battery fault warnings for reasons other than totally
discharged or defective batteries. Such warnings could also indicate excessive contact resistance
(> 200 mOhm) at the battery terminal clamps or connecting cables.
