The consumers can choose other electrical equipments to connect with MS1000, making good preparation as followed:
For during the operating, the LHD may couple the signal of the protected device(power cable),causing voltage surge or current impact to the input terminal of the connecting equipment.
Because long-length use of LHD during the operation, there may be power frequencyor radio frequency from LHD itself interfering the signal.

This analysis should depend on the technical parameters of MS1000, which will be introduced in detail later in this manual.
If any other queries relating, please contact us for more information. Our engineers will provide technical support.

The linear heat detector is a type oChemical Equipment & Machinery f fire detector with advanced functions, which meet all kinds of fire protection requirements in any inflammable sites. Though the detector has strong protective outer jacket to prevent damage, more attention should be paid during the installation due to the partial and internal damage cannot be found immediately. The damaged cable may cause the alarm of system malfunction or alarm during the future use. As a result,the followings should be paid attention to:
1. Forbid heavy objects overwhelming the heat sensing cable;
2. Forbid bending or turning the heat sensing cable with an acute angle;
3. Prevent corrosion;
4. Forbid using nonstandard accessories on the linear heat cable.
5. "Fire Test"pushbutton on the End of Line UniPaper Machinery t is for testing use only, it must be restricted to prevent accidental or mistaken use.
It comes to different fire detecting results due to different methods of installation, so we need take all the following factors into consideration, including the height, the structure, the obstruction, the air flow and so on, to prevent improper installation adversely affecting the normal use of the detector.The installation spacing of LHD
Characteristic features of LHD makes itself become the best choice of fire alarm system for applications in high risk of flammable areas, major types of induMachine Hardware strial and commercial places, especially in some harsh environments where spot-type detectors cannot be installed.
The LHD of Shenyang P.T.Shas been widely applied in industrial warehouses, workshops, etc. The detector can be installed at the ceiling level or the side wall depending on the features of the protected device, getting the same detecting result as the spot-type detectors'. How to determine the installation spacing?
There are different instructions from UL and FM standards, according to their own test requirements, the detector should match the figures below:ModelApprovals/Max. Listed SpacingFMUL/cULMS1000 68ºC

Special applicationsN/A
Special applicationsBut the figures above are for reference only, it is rather difficult to determine the practical installation spacing of the LHD, for we can not predicate the information of the fire, such as area, size, location and heat quantity. Furthermore, the LHD detect the fire temperature normally through the air radiation, it is more difficult to gain an accurate spacing data of LHD installation. We should design and lay the LHD with practice, properly reduce the spacing among the LHD to guarantee the accurate fire alarm. 5m spacing among LHDs is the best distance to get good detecting performance on our experience.We should design and lay the LHD with practice, properly reduceCutter & Tongs the spacing among the LHD to guarantee the accurate fire alarm. 5m spacing among LHDs is the best distance to get good detecting performance on our experience.
