5.12 CONTROL PANELS PARALLEL OPERATION
Fig. 8 presents the connection method of a common sound signalling device to two control panels
and possibility to transmit a common alarm and fault signal to the monitoring system.
In the case of an acoustic signalling device of resistance > 10 kΩ, the control panels can indicate an
external devices fault. In such the case it is necessary to install additionally loading resistors of 10 kΩ
resistance in parallel to each LA line. In order to supervise properly the alarm lines status, the
resistors should be connected at the lines ends, close to the acoustic signalling device.
The acoustic signalling device silencing during the alarm mode is possible from the control panel that
has evoked the alarm.
6 POWER SUPPLY
6.1. BASIC POWER SUPPLY
The control panel is primarily supplied by 230 V/50 Hz mains. A voltage alteration 10 % and -
15 % range does not influence the control panel proper operation.
6.2. RESERVE POWER SUPPLY
In case of mains voltage outage, the control panel is supplied from reserve battery cluster of 24 V
nominal voltage and 17 Ah capacity. A switch-over from the main power supply to the reserve one is
carried out automatically, without any break in power supply. The control panel, supplied from the
batteries only, without any additional device power consumption, is able to operate within 72 h in
the quiescent mode and + 0.5 h in the alarm mode. The control panel may operate being supplied
from a battery cluster of higher capacity – up to 36 Ah. In this case the battery cluster should be
located as close to the control panel as possible, the connecting cables should be of resistance lower
than 0.5 Ω and the internal batteries should be disconnected. Parallel batteries operation is allowed
only in the case of the same electrical parameters.
The external batteries enable connection of additional devices that consumes current during the
control panel quiescent mode. The battery cluster is charged automatically by the control panel
power supply unit.
The efficiency of both the batteries and charging device is constantly monitored and any fault is
being signalled. The battery is recognised as inoperative when its internal resistance increases and
exceeds 2 Ω.
Power consumption from a battery. In the quiescent mode, without the basic power supply, with
the full quantity of fire warning devices in 24 detection lines, but without additional device power
supply, the control panel current consumption does not exceed 228 mA.
