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 DT851 relay module provides two control relay outputs which will be activated simultaneously. When the outputs are activated, the device LED will indicate the event condition by red blinking. A return to normal condition will cause the event to disappear and the device LED indicator will return to the red idle condition. The DT851 is an intelligent addressable module and takes one address on the Signaling Line Circuit (SLC) or Data Communication Link (DCL) of the fire alarm control panel. It is a UL listed product according to UL864 for Fire Protective Signaling Systems for indoor use.
