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 9.5V
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 power supply board.
Exhausted batteries (off-load voltage U
Only the battery types approved from Esser by Honeywell 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 charged batteries.
