Applied where other types of fire detection are unsuitable
Operation
Alarmline Digital cable operates by short-circuiting in a fire condition or where acceptable operating temperature levels are exceeded, to provide a quick, positive and reliable signal.
Alarmline Digital may be used as a stand-alone detection facility with a sensor open circuit FAULT or short circuit FIRE condition, monitored by an associated simple electrical device.
As an integral part of a fire protection system, Alarmline Digital cable may be used as a conventional detector and operate automatic extinguishing systems via an Extinguishing Control
Panel (ECP). See KIDDE FIRE
PROTECTION datasheet E9832-327
As a cable and detector in one, installed close to potential sources of fire, Alarmline Digital cable provides economical detection for a wide range of risks which include:
Rack storage
Vehicle engine bays
Floating roof fuel storage tanks
Turbines
Boiler fronts
Ships’ holds
Rail locomotives and rolling stock.
All these risks fall well within
Alarmline Digital cable’s continuous operating ambient limits of -65°C to +200°C.
Installation
Ease of handling and stripping of the cable permits quick installation and allows conventional or proprietary methods of support to be employed.Nail type cable clips should not be used. Care must be taken to avoid mechanical impact, kinking, unacceptable heat sources or other factors which may affect the integrity of the cable.
