Type 1 Alarm Cable
Type 1 alarm cable has a maximum conductor resistance of 100 ohm/km with copper conductors and an LSNH sheath, more flexible and able to run greater distances than Type 3 alternatives, and suitable for public buildings.
Type 1 alarm cable is an 8 core cable with copper conductors and a maximum resistance of 100 ohm/km, giving it the reach to run further than a cheaper Type 3 alarm cable before signal quality suffers. It is supplied by Webro on a 100 metre reel with a white LSZH sheath.
What to look for
- 8 core, unscreened, copper conductors
- CPR class Cca, relevant to the fire rating required for the building
- White LSZH/LSNH sheath, suitable for use in public buildings
Type 1 is the better choice for longer alarm runs; where the run is short, compare Type 3 Alarm Cable within Alarm Cable.
