TECHNICAL DATA

Protective switching unit BKZ - 8 "SEVER" (hereinafter BKZ - 8) is designed to distribute the current of the power supply of the fire alarm equipment over 8 channels and protect each channel by current using fuses. Each channel is equipped with a fuse and a red indicator (indicators "Channel output" (8 pcs. )) Indicating channel overload by current and fuse failure. Green LED "Input" indicates the presence of voltage at the input. BKZ - 8 is designed for continuous round - the - clock operation.

The location of the blocks, fuses and indicators is shown in Figure 1.

• MAIN TECHNICAL CHARACTERISTICS:
• Input supply voltage - from 10 to 30 V.
• The number of channels is 8.
• Total switched current - 5 A.
• The rated output current of the channel is 0.6 A.
• Temperature range - from minus 50 to + 50 ° С.
• The degree of protection provided by the shell in accordance with GOST 14254 is IP 66.
• Overall dimensions - 200x175x50 mm.
• Weight no more - 0.6 kg.
• The number of sealed leads - 6. The diameter of the connected cable is 6 - 14mm.

USING BKZ - 8

Switch on the power supply. The green POWER indicator should turn on. Indicators "1" - "8" must be off.

If an overcurrent occurs during operation, the red indicator of the corresponding channel will turn on. At the same time, the voltage on the remaining channels remains.
To eliminate the causes of the overcurrent, turn off the power source (or, by removing the cover of the UPC, disconnect the wires going to the terminals of the channel with the red indicator turned on - in this case, the voltage on the other channels remains). After eliminating the causes of the overload, turn on the power source (or connect the wires), replace the blown fuse - the UPC will restore operability.
