- Commodity name: JTF-GOM-D21 Ex point-type composite smoke - sensing temperature fire detector
JTF-GOM-D21 Ex point-type composite smoke sensing temperature fire detector and explosion-proof safety grid are used together to form a distributed intelligent system connected to the loop bus of JB-QB-F61 fire alarm controller, whose 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: GB4715-2005 "point type smoke detector", GB4716-2005 "point type temperature detector", GB 3836.1-2010 "Explosive gas environment electrical equipment Part 1: General Requirements, GB 3836.4-2010 "Electrical Equipment for Explosive Gas environment Part 4: intrinsically safe type" i ", meet the enterprise standard Q31/0115000537C002-2017 "Point-type composite smoke and temperature fire detector". The explosion-proof mark is Ex ia ⅡC T6GB, which is especially suitable for the fire detection and alarm in the explosive gas environment of ⅡC class T6 temperature group except hydrogen gas in coal mine. 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.
A2R class has differential temperature alarm function.
