1 - Composition
The power supply section of the control panel complies with the requirements of the standard EN 54-4. It consists of a primary
power supply (PS - power supply) and a secondary power supply (SD - storage device).
The primary power supply consists of a modular switching power supply, capable of providing 2.7A/28V direct current.
The secondary power supply consists of two 12V/7.2Ah batteries connected in series with each other. It is imperative that the
batteries are always two. Never use batteries of different manufacturers, capacities and/or production lots.
Capacity lower than 7.2Ah, besides reducing the autonomy, distort the resistance values causing possible improper failure signaling.
2 - Mains power LED
In the normal operating state (no active failure), only the green MAINS POWER LED is on.
3 - Protection against battery reverse polarity
The power supply section is protected against reverse battery polarity by fuse (F 3.15A, 250V 5x20mm).
4 - Automatic system failure acknowlegment
With the option enabled, the return to normal operating conditions automatically acknowledges all the noti fi cations and removes
the failure noti fi cation from the event queue.
With the option disabled, the return to normal operating conditions does not automatically acknowledge all noti fi cations.
It is necessary to reset the control panel.
5 - Switch on with battery power only
Control panel switch on with battery power only is normally inhibited. To enable it, insert the JP1 jumper on the CPU board.
Warning: when mains power is available, it is mandatory to remove the JP1 jumper. If the jumper remains inserted, there is a risk that:
• The automatic battery test provides incorrect results
• The automatic disconnection of the battery in case of deep discharge no longer works
• Power supply is overloaded
