<strong>Power</strong> supplies <strong>of</strong> voice alarming systems<br />
ZDSO400<br />
Voice alarming systems require a guaranteed source <strong>of</strong> voltage to ensure <strong>supply</strong> <strong>of</strong> power over a specified duration needed by<br />
efficient evacuation from endangered zones.<br />
<strong>MERAWEX</strong> has developed and manufactures power supplies <strong>of</strong> series ZDSO400 for voice alarming systems Praesideo and Plena by<br />
Bosch, and Sinaps by Ultrak and Honeywell. A standard 19” rack cabinet <strong>of</strong> height up to 50U forms <strong>the</strong> main frame <strong>of</strong> <strong>the</strong> system to<br />
host not only elements <strong>of</strong> <strong>the</strong> power <strong>supply</strong>, but also elements <strong>of</strong> <strong>the</strong> voice alarming system (amplifiers, controllers, etc.). The power<br />
system takes care about <strong>supply</strong>ing <strong>the</strong> mains (primary) power as well as <strong>the</strong> backup power <strong>of</strong> 24V or 48V from own battery banks.<br />
The battery banks are protected against too deep discharge. It is possible to apply a single rack or a set <strong>of</strong> a few racks – <strong>the</strong> system<br />
allows for operation in a distributed mode. Reliability <strong>of</strong> <strong>the</strong> system can be improved by adding a supplementary power <strong>supply</strong> unit<br />
which can be used also to increase charging current. The power supplies ZDSO400 comply with EU directives: CPD (constructive<br />
products) 89/106/EEC, LVD (low voltage devices) 206/95/EC, EMC (electromagnetic compatibility) 204/108/EC.<br />
FEATURES AND FUNCTIONS OF THE POWER SUPPLY<br />
ZDSO400<br />
• no limitation as for <strong>the</strong> number <strong>of</strong> rack cabinets in <strong>the</strong> system<br />
• distribution <strong>of</strong> <strong>the</strong> mains and backup power to <strong>the</strong> modules <strong>of</strong><br />
<strong>the</strong> voice alarming systems<br />
• alarming in case <strong>of</strong> detected malfunctions <strong>of</strong> <strong>the</strong> system<br />
• possibility to connect with a fire alarm control panel<br />
• precise regulation <strong>of</strong> floating mode voltage – temperature<br />
compensation<br />
• fast charging <strong>of</strong> <strong>the</strong> battery with <strong>the</strong> charging current limitation<br />
• monitoring <strong>of</strong> low and high battery voltage<br />
• monitoring <strong>of</strong> continuity <strong>of</strong> battery circuits and protection <strong>of</strong><br />
batteries against too deep discharge<br />
• surge protection <strong>of</strong> <strong>the</strong> mains line<br />
• visual, sound and remote indication <strong>of</strong> alarms<br />
• history <strong>of</strong> events recorded in non volatile memory<br />
• wheels as optional outfit <strong>of</strong> <strong>the</strong> cabinet<br />
indication <strong>of</strong> high resistance <strong>of</strong> <strong>the</strong> battery bank<br />
and circuits connected to it<br />
Having conducted supplementary tests against EN 54-4/A2, conformity and approval was<br />
recertified for <strong>the</strong> power supplies.<br />
certificate <strong>of</strong> conformity: certificate <strong>of</strong> approval: date:<br />
ZDSO400D-AK4 nr 2144/2006 0463/2008 19.10.2009<br />
ZDSO400E-AK3 nr 2157/2006 0343/2008 24.09.2009<br />
ZDSO400D-AK3 nr 1438/CPD/0129 0456/2008 24.09.2009<br />
According to <strong>the</strong> obligatory since September 1, 2009 amendment A2 to EN 54-4 <strong>the</strong> power supplies have<br />
been extended by a measuring set consisting <strong>of</strong> <strong>the</strong> battery resistance meter RMB-1 and DC meters<br />
CP-100 in each battery string. The requirement to monitor high resistance <strong>of</strong> <strong>the</strong> battery bank is included<br />
in <strong>the</strong> standard EN 54-16 for voice alarming systems too, because this standard refers to EN 54-4.<br />
Adjustment <strong>of</strong> <strong>the</strong> power supplies to <strong>the</strong> amendment A2 is <strong>the</strong> necessary and sufficient condition that<br />
complete voice alarming systems continue to comply with <strong>the</strong> technical approvals used in <strong>the</strong> process<br />
<strong>of</strong> <strong>the</strong>ir certification. The monitoring <strong>of</strong> resistance <strong>of</strong> <strong>the</strong> battery circuit (backup source <strong>of</strong> power)<br />
increases reliability <strong>of</strong> <strong>the</strong> power system, thus also reliability <strong>of</strong> <strong>the</strong> whole voice alarming system.
