Fire alarm installation cable with PVC insulation and screen and Al-foil screen

alt. mark: BMK

	Application	Standards
	Installation cable for transmission of fire alarm signals, for fixed installation within dry or damp premises, under or on plaster, also for fixed installation on external walls. Not for direct laying in ground or water, not intended for supply purposes. Electrostatic screen protects transmission circuits against external disturbing electromagnetic impacts.	DIN VDE 0815
