Emergency Power Supply - Honeywell IQ8Control C Installation Instruction

Fire Alarm Control Panel IQ8Control C/M
Several alarm circuits on one power supply unit
If several visual/acoustic alarm devices are switched on e.g. via the 3 relay micro module (part no.
787531), 4 relay micro module (part no. 787530), the 4 zone/2 relay esserbus
no. 808613/808613.10) or the 12 relay esserbus
their power supply is provided by a joint power supply unit, then the installer must ensure that there
is a staggered backup concept.
As a rule, several fuses with different fuse values and different response characteristics are
connected in series. The response behaviour also always depends on the preload of the fuses.
In order to carry out this wiring according to the standard, it must be ensured that in the case of a
short circuit, it is not the power supply unit fuse that responds but instead a fuse for the respective
alarm area.
It is thefore paramount that every single alarm area is protected via a separate external fuse. The
8-fold fuse card (part no. 382040), for example, can be used for this purpose.
The fuse values depend on the number and type of the devices used and must always be
determined for the specific object.
Recommendation: Small fuse value

4.1.3 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 10.5V 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 9.5V
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 BR2 on the basic circuit board .
Exhausted batteries (off-load voltage U
Only the battery types approved by the Esser by Honeywell Fire Alarm Control Panel 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.
