GENERAL SAFETY RULES

Before installation, read the instruction manual to avoid errors that

can damage the device and give you an electric shock.

 Before installation, cut off the voltage in the 230 V power-supply circuit.  To switch power off, use an external switch, in which the distance between the

contacts of all poles in the disconnection state is not less than 3mm.

 The shock protection circuit shall be done with a particular care: the yellow and green

wire coat of the power cable should be connected to the terminal marked with the grounding symbol on the PSU enclosure. Operation of the PSU without the properly made and fully operational shock protection circuit is UNACCEPTABLE! It can cause damage to the equipment or an electric shock.

 The device should be transported without batteries. This has a direct impact on the

safety of the user and the device.

 Installing and connecting the power supply must be carried out without batteries.  When connecting batteries to the power supply, pay particular attention to the correct

polarity. If necessary, it is possible to permanently disconnect the battery from the power supply systems by removing the F

BAT

fuse.

 The power supply is adapted to be connected to a power distribution network with an

effectively earthed neutral conductor.

 Ensure a free, convection air flow around the enclosure. Do not cover the ventilation

openings.

3. Technical description.

3.1. General description.

The power supply modules are designed for mounting in an additional housing. In order to meet the requirements of the EN54-4 + A1 + A2 and EN12101-10 + AC standards, the enclosure must be of appropriate construction. IP30 protection class is required.

Buffer power supply modules has been designed for an uninterrupted supply of fire alarm systems, smoke and heat control systems, fire protection equipment and fire automatics requiring stabilized voltage of 24 V DC (±15%). The power supplies are fitted with two independently protected AUX1 and AUX2 outputs, which provide a voltage of 27,6 V DC and the total current efficiency depending on the version:

In case of power loss, the PSU switches to battery power, providing uninterruptible power supply. The power supply modules units works with maintenance-free lead acid batteries made with AGM technology or gel technology.

3.2. Block diagram.

The power supply modules has been manufactured based on a high-efficiency system of AC/DC

converter. Applied microprocessor circuit is responsible for the full diagnostics of the PSU parameters and batteries. The figure below shows a flowchart of the power supply, along with selected functional blocks which are essential for the proper functioning of the unit.
