SD388 Smoke Detector

Our SD388 smoke detector features an integrated heat detector for SD 388-2H and SD 388-4H models. With a size of 102mm in diameter and 43mm in height, this detector provides an independent smoke and heat detection. The alarm will be activated if either of them detects emergencies. It meets the requirements of UL 268 and EN 54-7/5, while it also passes NFPA 72 standards.

Besides, our smoke detector provides fast and reliable response for photoelectric smoke or heat (135℉) detection. It provides fire detection by acting as a smoke sensor and/or a 135℉ heat detector at the same location. With advanced detection and discrimination algorithms, our smoke detector also features an easy installation and maintenance. There is no need to replace the durable sensor head, while the SMD circuit board also ensures quality and reliability. N/C (normal/close)-N/O (normal/open) selectable relay output is provided, while auto reset function is optional for 4 wire models. In addition, we offer you 5 year limited warranty to our product.
