RE-2554

RE-2554

The RE-2554 is a microprocessor-based, UL-listed 4-zone conventional fire alarm control panel designed to deliver reliable fire detection for a wide range of applications. It features a 16 × 2 LCD display for clear system status and alarm information, with four independent detection zones for accurate area identification. Includes three common potential-free relay contacts and two common Notification Appliance Circuit (NAC) sounder outputs, ensuring effective alarm signaling and system integration. An inbuilt RS-485 communication port allows seamless connectivity with repeaters for extended monitoring. Operates on a switch-mode power supply (SMPS) with battery polarity protection and deep discharge protection for safe and stable performance. Suitable for schools, hospitals, hotels, banks, commercial buildings, and small to medium-scale industrial facilities.
