300V Mica+LSZH Insulated & LSZH Sheathed Fire Alarm Cables

JE-H(St)H…Bd FE180 E90. (CU/MICA+LSZH/OSCR/LSZH 300V Class 1 )
JE-H(St)H…Bd FE180 E90 BMK* (CU/MICA+LSZH/OSCR/LSZH 300V Class 1)

APPLICATION
The cables are used for the internal wiring of building when the circuit integrity during fire is paramount. The cables are intended for use in fire fighting plants with mica tapes, with and without Aluminum foil and LSZH outer sheath.The fire alarm cables with 30 to 90 minutes circuit integrity should be used for control voltages and data transfer in alarm and fire alarm systems, where a system circuit integrity E30/E60/E90 depending on lay system in accordance with DIN 4102-12 is required. The circuit integrity is guaranteed with a test voltage of 110V.

STANDARDS
Basic design to VDE 0815

FIRE PERFORMANCE

Note: Asterisk * denotes superseded standard.

CABLE CONSTRUCTION
Conductors: Solid annealed bare or tinned copper sized 0.8mm as per class 1 of VDE 0295/IEC
60228.
Fire Barrier: Mica glass tape.
Insulation: Thermoplastic LSZH compound HI1 as per DIN VDE 0207-23.
Cabling Elements: Insulated cores are twisted to form pairs with varying lay length to minimize
crosstalk. Two-pair cable had four cores laid in quad formation.
Cabling: Pairs are cabled together. In cables with 8 pairs or more, 4 pairs are assembled to form a
bunch, the bunches are then cabled together.
Cable Core Assembly: The twisted pairs are stranded to the core in layers.
Core Wrapping: One or more non hygroscopic polyester tapes are helically or longitudinally laid with
an overlap prior to sheathing.
Screen: A laminated Aluminum/Polyester tape in contact with solid copper 0.6mm or 0.8mm drain
wire.
Ripcord: Nylon ripcord may be placed parallel to the cores to facilitate sheath removal.
Drain Wire: A solid tinned earth/continuity wire shall be laid longitudinally for screened cables.
Outer Sheath: Thermoplastic LSZH compound HM2 as per DIN VDE 0207-24 .

COLOUR CODE
Quad colour in each bundle:
Pair 1: Blue-Red
Pair 2: Green-Yellow
Pair 3: Green-Brown
Pair 4: White-Black
The individual bundles are identified by a numbered helix.
