LHD: Linear Heat Detection, as illustrated below, is easy to design, install, operate, and maintain. A typical system begins with any approved conventional or addressable fire alarm panel. A Distance Locating Module may be added to identify where the overheating condition is occurring. Leader wires are then run in conduit from either the panel, an addressable module, or the distance locating module, to the beginning of the zone.
Several styles of mounting accessories are available which are designed to accommodate different types of hazards. At the end of each zone, the is terminated in an ELR-Box using the end of line resistor supplied by the panel manufacturer or looped back when using a 4 Wire (Class “A”) configuration. SafeCable.
FIRECEL SR 125 E30 are wiring cables for telecommunication and information processing systems where absence of halogen and improved properties in case of fire and specified continuance of insulation effect when exposed to flame.
For fixed installation in dry and humid premises,may be embedded in plaster, not for power supply, external use or underground laying.
The IS FlashDome is an intrinsically safe strobe for use in hazardous areas. Certified to ATEX and IEC Ex, the IS FlashDome is designed for use in Zones 0, 1 & 2.
In order to be intrinsically safe, the IS FlashDome must be powered via an approved 28v 300Ohm zener barrier or galvanic isolator.
Suitable barriers and isolators are available from Vimpex.
