Brief Introduction
|
| TY-HS-BK801Ex Line Beam Smoke Fire Detector is an intrinsic satety reflection line infrared beam smoke fire detector which is in accordance with the national standard of GB14003-2005, GB3836.1-2000 Electrical Apparatus for Explosive Gas Atmosphere Part 1: General Requirement, and GB3836.4-2000 Electrical Apparatus for Explosive Gas Atmosphere Part 4: Intrinsic Safety Type “i” with Exd[ia]II CT6 as the Flameproof Mark. The product is applicable to Zone 1 and Zone 2 explosion prevention places with explosion prevention requirements in the oil, chemical industries, etc. The detector contains a group of alarm passive normally open contacts and a group of fault alarm normally closed contacts as well as 0-20mA standard signal output to be conveniently connected with the fire alarm system and DCS system of plants of fire fighting equipment. |
| Characteristics |
|
- Wide operating voltage range and wide protective area
- Built-in microprocessor, intelligentized fire alarm and fault judgment - Self-diagnosis capability, monitoring of faults in the detector - Field setup of two levels of sensitivity - Easy integration of the transmitting part and the receiving part, simple and convenient installation, good light path collimation - Fire alarm and fault passive output contacts and standard 4-20mA standard power supply output - Smart design of the detection light path, high antijamming performance, seal protocol, corrosion protection and waterproof performance - Automatic calibration function to enable a single person to complete debug within a short time, simple operation - Automatic compensation function, and automatic compensation for factors of received signal reduction such as dust pollution, position deflection, ageing of the transmitting tube, etc. to some extent |
