2.6 Describing the general inputs and outputs of the panel
On the printed circuit board located to the left side of the panel you can see the general purpose input and output
terminal blocks. The figure below shows the terminals of the circuit board and they are described from left to right.
The next 3 outputs are relay outputs that are mandatory by the European norms. These outputs are connected to
the building BMS and relays that require information regarding the status of the central battery illumination system.
FAULT YES / NO
. Fault relay contact. When there is no system fault, the NO contact is active otherwise the YES
contact is active.
SUPPLY MAINS / BAT
. Relay contact that indicates what source of voltage is powering the system. When the
power is supplied by the batteries then the BAT contact is active and when it is powered from the mains230VAC
the MAINS contact is active.
OPERATION OFF / ON
. Relay contact indicating the operation status of the panel. When the panel is operating,
the ON contact is active. When the panel is shut down or is in cut-off mode the OFF contact is active.
The next 4 outputs-inputs are not relay contacts and they are supplied by live voltage so safety has to be
considered when connecting those terminals. Don’t connect the mains power cord before completing the following
connections (if any).
BAT FAN
. Output for connecting an AC 230V cooling fan (optional). (fuse 0.3A/250V)
STRCS SWITCH
. This input is used to connect in parallel, common staircase light buttons. By programming, some
illumination zones can be activated for a pre-programmed time period by pressing one of the staircase light
buttons.
3 PHASE MONITOR
. This contact by default has a jumper installed. When the contact is open then the panel
activates the emergency luminaries. By using one or more mains voltage monitors you can activate the emergency
