Recoverable differential constant temperature 85°C

product description:

JTW-LCD-ZS5000 series of recoverable cable-type linear differential temperature fire detectors (hereinafter referred to as detectors) are intelligent linear temperature fire detectors developed by our company with independent intellectual property rights. The detector is designed based on the National Standard of the People's Republic of China GB16280- 2014 Line Type Heat Fire Detectors. The product consists of three parts: signal processor, temperature sensing cable, and terminal processor. It can be connected with any fire detector from any manufacturer at home and abroad. The alarm controller is coupled to form an automatic fire detection alarm system, which can be widely used to protect the following objects:

◇Cable facilities: cable tunnels, cable shafts, cable mezzanines, cable bridges, etc.;

◇Power facilities: power distribution devices, switchgear, transformers, reactors, etc.;

◇Oil products, gas, hydraulic stations, oil depots, oil areas, gas areas, oil furnaces, gas boilers, spray (baking) paint rooms, etc.;

◇Belt transmission facilities, material transportation, material transportation belts, and automated production lines.

 

Features:

◇Detector category: Recoverable cable-type linear differential fixed-temperature fire detector;

◇The detector has two fire detection and alarm functions: differential temperature and fixed temperature;

◇The temperature-sensing cable uses oxygen-free copper alloy as the conductor, which is resistant to corrosion and aging. The cable adopts a cable-type twisted five-core structure with a metal shielding layer inside, which has strong anti-electromagnetic interference ability;

◇The detector can quickly respond to the alarm function of 100mm small size flame;

◇The detector has fire alarm normally open contact output, fault normally open and normally closed contact output;

 

Technical Parameters:

◇Working voltage: DC24V Allowed range: DC20V～DC28V;

◇The static monitoring current of the detector is less than 10mA, and the alarm current is less than 20mA;

◇The maximum operating length is 150 meters, and the minimum standard alarm length is 1 meter;

◇Relative humidity ≤96%, no condensation;

◇Overall protection level: IP68;

◇Explosion protection: Ex ia [ia Ga] IIC T6 Ga;
