Now obsolete; replacement controller here. If the cable needs changing too, please get in touch with us; an alternative controller will be required to work with the latest cable.
The Kidde LHD4 AlarmLine Linear Heat Detector is a two-component heat detection system. It comprises the LHD4 interface module and heat sensor cable. The cable senses a temperature change, which provides an exponential decrease in resistance; the interface module computes this and provides an output to the control panel if the user-predetermined alarm set point has been exceeded.
Ideal for deployment where point smoke or heat detectors are not permitted. Suitable for use in confined spaces or hard-to-access areas or hazardous areas, with intrinsically safe options available. Installation is easy; detector cable can surround the protected area or be placed around machinery. Alarmline cable is supplied in standard PVC, Nylon-coated PVC or Bronze-braided PVC.
If a fire or overheating occurs, the Alarmline cable can be restored up to temperatures of 257°F (125°C). Higher temperatures will warrant replacement.
False alarm protection is built-in; the system will output a trouble condition in the event of an electrical fault or short circuit.
Examples of deployment are: open areas, cable trays, storage racks, freezer warehouses, fuel tanks, cooling towers, waste fuel drum storage, escalators and power distribution.
Features
- Localised installation at the point of risk.
- Pairs with most central control panels.
- Program an adjustable alarm setpoint.
- Durable; selection of cable options for applications.
- Reliability; false alarm protection, reusable cable after an event (analogue only).
