Power Packs for DICTATOR Hold-Open Systems
There have to be used approved power packs to supply hold-open systems. They change the 230 VAC input voltage to a 24 VDC output voltage.
Which power pack to select depends on the power consumption of the components of the hold-open system.
The S400 signal control includes beside the power pack an additional emergency power supply. This allows to supply signallers in case of a power cut, so that even then persons can be warned during the closing of e.g. a sliding door by acoustic or optical signals.
Warns during the closing of fire protection doors according to EN 14600:2005, point 220.127.116.11 – also during a power cut
