The HASD-YW-2 explosion-proof composite pyrotechnic temperature and fire detector (detector for short) is a non-coded switch-type (relay output) detector. This detector has been equipped with a safety barrier. Adopting special process treatment, the working performance is stable and reliable. Can be used with any fire alarm controller from any manufacturer at home and abroad. This product complies with the requirements of the GB3836 series of standards. It has been certified by a nationally designated testing agency and has obtained an explosion-proof certificate.
