Fire Resistant Fire Alarm Cables

225V SR Insulated & LSZH Sheathed Fire Alarm Cables BMK*

JE-SH(St)H…Bd FE180 E30 BMK (CU/Mica+SR/OSCR/LSZH 225V Class 1 )

APPLICATION

The 25V SR Insulated & LSZH Sheathed Fire Resistant Fire Alarm 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.

CABLE CONSTRUCTION

Conductors: Plain annealed copper wire, sized 0.8mm solid according to IEC(EN) 60228 class 1.
Flame barrier: Special fire proof tape.
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.
Overall Screen: Aluminum/polyester tape with tinned copper drain wire.
Outer Sheath: Thermoplastic LSZH compound HM2 as per DIN VDE 0207-24

COLOUR CODE

Insulation Colour:
Each bunch blue - red / grey - yellow / green - brown / white - black
Bunch identication plastic numbered tape
Sheath Colour:
Colour red with printed " BMK - BRANDMELDEKABEL" denoting fire alarms.
