Linear Heat Detection
Linear Heat Detection (LHD) is a versatile and economical fire
detection product. Designed for use in a wide variety of fire and heat
detection applications, LHD cable is particularly suited for harsh
environmental conditions, where maintenance access is in a physical or
hazardous area, and/or where there is a requirement to cost-effectively install
fire detection in close proximity to the hazard.
Linear Heat
Detection cable is a combination of advanced polymer and digital technologies
that can detect heat conditions anywhere along the length of the cable. The
cable is comprised of two tri-metallic conductors individually insulated with a
heat sensitive polymer outer-layer, and engineered to break down at specific
fixed temperatures. This allows the twisted conductors to make contact and
initiate a fire alarm condition at the control panel, without any calibration
for changes in the ambient temperature. Nor is it required that a specific
length be heated in order to initiate a fire alarm, adding to the versatility
of this unique product.
Alarm Point Location Setup
Each Protecto wire zone is field
calibrated after installation to eliminate copper feed cable resistance from
the Alarm Point Location reading. This is done by manually shorting the
detector at the beginning of the zone and adjusting the display to zero
"0000".
Alarm Point
Location Reading
When an overheat (alarm) occurs
in a zone, an alarm point reading is taken either *manually or *automatically
at the control panel. This reading represents the linear distance to the
actuated point along the detectors length.
For further flexibility, Linear
Heat Detection cable can be utilized with fire alarm control panels by
utilizing either addressable monitor modules on an intelligent system, or
by connecting the cable directly to the detection circuit of
a conventional fire detection and control panel. In addition, the distance
locating option allows the control panel to identify and display the exact
location, in feet or meters from the fire panel, where the heat source
interacted with the linear heat detection. That's a tremendous amount of
valuable information in a small, easy to install and maintain fire detection
package!
