Lightning protection units DNP508 and DNP5082 are designed to protect electronic devices from electromagnetic pulse of lightning.
Product Description
Lightning protection units DNP508 and DNP5082 are designed to protect electronic devices from electromagnetic pulse of lightning.
When lightning strikes, DNP508 limits the maximum voltage of the line to 150/180V, and the terminals of the Control Panel to 46V for DNP508 (and 72/53V for DNP5082).
The device is available in two versions:
– DNP508 – to protect inputs of the lines of conventional Fire Control Panels;
– DNP5082 – to protect inputs of the loops of Fire Control Panel IFS7002, manufactured by UniPOS.
Lightning protection unit DNP508 (DNP5082) is to be mounted close to the Fire Control Panel or at a place, where the fire alarm line loops) are extended beyond the building (outdoors).
