- Commodity name: JTW-ZDM-D23A Ex point temperature detector
JTY-ZDM-D23A Ex point type optical smoke detector and explosion-proof safety grid are connected to the circuit bus of JB-QB-F61 fire alarm controller to form a distributed intelligent system, and its address is coded by handheld addresser. The detector adopts the electronic surface mounting process and has been inspected and audited by the Fire Products Qualification Assessment Center of the Ministry of Public Security, the National Fire Electronic Products Quality Supervision and Inspection Center and the National Explosion-proof Electrical Products Quality Supervision and Inspection Center. Meet the national standards: GB4715-2006 "point type temperature detector", GB 3836.1-2000 "Electrical Equipment for Explosive gas environment Part 1: General requirements", GB 3836.4-2000 "Electrical equipment for Explosive gas environment Part 4: intrinsic safety type" i ". The explosion-proof mark is Ex ibⅡB T6GB, especially suitable for petroleum, chemical industry and other ⅡB T6 temperature group of explosive gas environment fire detection and alarm. Has "high" protection level and is not an ignition source under normal operation or expected failure conditions.
Strong anti-interference ability, including damp, high and low temperature, electromagnetic interference, vibration and so on.
The built-in CPU can store, analyze and judge the data collected by itself, and has the function of self-diagnosis.
Communicate with the controller through the field two bus.
Early alarm is realized by detecting the ambient temperature.
