FM Proved Digital Type Linear Heat Detectors
1. Application scope
Compared with other kinds of detectors. MS1000 digital linear heat detector provides a very-early alarm detecting function to the protected environment. The detector can be known as an intelligent "switch" type detector. The polymers between the two conductors will break down at specific fixed temperature allowing the conductors contact, the shot circuit will initiate the alarm. The detectors has a continuous sensitivity. The sensitivity of linear heat detector will not be influenced by the environment temperature changing and the length of detection cable using. It does not need to be adjusted and compensation. The detector can transfer both alarm and fault signals to control panels normally with DC24V or without DC24V.
2. Classification
| Conventional type |
This type of Linear heat detection cable is the most widely indoor used with strong stability |
| CR/OD Type |
CR/OD type not only has good UV resistance and good weather resistance, strongly recommended for outdoor using even under bad weather conditions, but also with high performance of acid resistant, alkali-resistant, salt spray resistant. |
| EP Type |
Explosion proof type. Two main application environments: harsh EMI environment and explosive hazardous environment. The outer jacket of this type is protected by woven metal mesh with good performance of anti-EMI and eliminating the surface static of the linear heat detection cable. We can use this type linear heat detection cable in explosive hazardous environment with safety fence. During the installation, please make grounding connection of the woven metal mesh. Used in harsh EMI environment, single end grounding connection or double ends grounding connection should be specified after analysis of the interference sources. |

MS1000-L Control Unit and Locator
Control unit MS1000-L is a controlling device to monitor the temperature change of sensor cable and connected to mainframe of intelligent fire alarming control panel.
MS1000-L performs continuous monitoring over fire alarm and open circuit of monitored area as well as distance from fire alarm position. These alarming signals are shown on the LCD and indicators of MS1000-L.
Since fire alarm has locking function, MS1000-L must be disconnected to power and reset after ALARM. While fault function could automatically reset, it means that after the clearing fault, the fault signal of MS1000-L is automatically cleared.
Features
Plastic shell: chemical resistance, aging resistance and impact resistance.
IP rating: IP66
With LCD, various alarming information could be shown
