Page 5: Principle Of Operation
Power supply design is based on so called direct buffering operation. Mains power supply (which has also role of a battery charger) is connected in parallel to outputs of ZDSO400-ER1 and external battery. When mains power is present then it is delivering power to outputs and simultaneously charging the battery. - Page 6 It causes that there are two circuits with different character of current sourcing: 1. amplifiers of VAS, sourced from outputs Out: a. when mains is present they are not sourcing current from ZDSO400-ER1; b. after mains failure, when there’s no fire alarm, they source very low current from power supply’s battery for their own needs;...

Page 7: Installation And Connection
At the rear side of power supply, next to mains socket, there is DIP switch, allowing setting of: battery capacity Cap, which will operate with ZDSO400-ER1. Setting the slide of the switch should be done according to calculation of capacity by DSO system calculator and taking into account the time of operation during watchdog and total power of all foreseen loudspeakers to be installed. - Page 8 Fig. 4 Look of the DIP switch for selection of capacity and battery circuit resistance with settings description 3.3. Connection Below table shows the types of connectors used in power supply with their maximum ratings and wire diameters. Table 3. List of ZDSO400-ER1 connectors Model Output Type of plug used Mains power IEC C13 1 pc.

4. First Start 4.1. The initial information The first start of the VAS system including the ZDSO400-ER1 and connected battery should be done by qualified service personnel of the Manufacturer or the properly trained authorized personnel. The tests during the first start of the system are necessary to ensure safe and reliable operation – both from the mains and battery backup power. - Page 11 VAS modules. Check the voltage presence and value by a voltmeter. In this state, the Mains LED on the front panel of the ZDSO400-ER1 should go dark and the Fault and Battery LEDs should be lit.

Page 14: Servicing
Most cases of malfunctions which can occur during device operation are indicated and handled by the microprocessor installed in the device. The ZDSO400-ER1 is equipped with 12 fuses for model 1 and 10 fuses for model 2. They can be replaced by qualified service personnel. These are fuses of output circuits –...
