225V SR Insulated & LSZH Sheathed Fire Alarm Cables BMK
JE-2G(St)H…Bd FE180 E30 BMK (CU/SR/OSCR/LSZH 225V 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 special ceramized silicone insulation, 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.

CABLE CONSTRUCTION
| Conductors |
Plain annealed copper wire, sized 0.8mm solid according to IEC 60228 class 1 |
| Insulation |
Fire resistant silicone rubber type HJ1 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 in concentric layers with suitable non-hygroscopic fillers |
| Fire barrier |
Special fireproof tape |
| Overall screen |
Aluminum/polyester tape with tinned copper drain wire |
| Outer Sheath |
Thermoplastic LSZH compound HM2 as per DIN VDE 0207-24. UV resistance, hydrocarbon resistance, oil resistance, anti rodent and anti termite properties can be offered as option |
