The UL listed Intelligent Fire Alarm System. D-TECTRON fire alarm systems can be configured with just a few devices for small size building applications, or networked with many devices to protect a large campus or a high-rise building. Simply add additional peripheral equipment to suit the application. Our advanced technology delivers supports the installers to do complete installation easily through simple steps. The inherent fault-tolerant characteristics of Analog/Address- able Technology boosts the reliability of D-TECTRON fire alarm systems. When combined with D-TECTRON smoke and heat detectors, these systems deliver a level of reliability and dependability for both small to medium size applications.
The D-TECTRON DT511 series intelligent plug-in smoke detectors is ideal for application where Freeze trouble slow-burning or smoldering fires are likely.
Model DT511 is a 2-wire photoelectric smoke detector that uses unique patented design optical sensing chamber. The detector is designed to provide reliable protection for open area and to be used with compatible UL listed control panels only.
