The use of intelligent and digital products is expanding rapidly in line with the development of science and technology, while the trend of intelligent development is also being adopted by the fire protection system. The LAD series: Enclosed Type Economical Security and Fire Alarm Power Supply, incorporates UPS, battery charger, and digital communication features. With its compact size, it not only free up space of the system, reduces design costs, but also improves system reliability at the same time.
The LAD series comes in two models: the “Basic” (LAD-120/240/360/600) and the “UART Communication” (LAD-360/600xU). Both adopted 1U slim design, in order to meet the application requirements of various fire protection system.
TTL Basic Model (Signal Only):
The purpose of TTL signal terminals is to detect AC OK, battery disconnect/reverse polarity, battery full, and discharge signals through external circuits.
• AC OK
• Battery Disconnect/Polarity Reverse
• Battery Low
• Battery Full
• Discharge
