Description  The Ravel Electronics RE-2554 is a microprocessor-based 4-zone conventional fire alarm control panel designed for reliable fire detection and notification management. The RE-2554 integrates supervised initiating device circuits, NAC sounder outputs, and relay signaling for use in small to medium commercial and institutional buildings. It supports smoke detectors, manual call points, and supervisory inputs while maintaining compliance with UL-864 and NFPA-72 standards.     Technical Specifications  Condition New/Never Used Surplus Brand Ravel Electronics Category Fire Alarm Control Panels Part Number RE-2554 Subcategory Conventional Fire Alarm Panels Zones Supported 4 Zone Class B Initiating Device Circuits Primary Power Input 110–220VAC ±10%, 50/60Hz, 2.5A Standby Power 24VDC via 2 × 12V sealed lead-acid batteries Charging Voltage 28.2V ±0.5V Charging Current 800mA maximum IDC Operating Voltage 14–21VDC nominal IDC Loop Resistance 100 ohms maximum Notification Circuits 2 NAC outputs, Class B Style Y NAC Current Capacity 1.2A total (0.6A per circuit) Relay Contact Rating 2A @ 30VDC, 0.5A @ 125VAC Display Type 16×2 Dot Matrix LCD with LED indicators Communication Interface RS-485 optional repeater connectivity Enclosure Construction Powder-coated CRCA steel cabinet Operating Temperature Range 0–49°C (32–120°F) Weight Approx. 6–8 kg (cabinet with boards, excluding batteries)   Information About  RE-2554 The RE-2554 is a UL-listed conventional fire alarm control panel from the Ravel Electronics RE-25xx series, engineered for four-zone fire detection applications in protected premises. The system is built with a rugged powder-coated CRCA steel enclosure and includes a 16×2 LCD interface with LED status annunciation for clear event identification. It is compatible with standard 2-wire and 4-wire smoke detectors, manual pull stations, and normally open contact devices across all supervised Class B initiating circuits. The panel incorporates key technologies such as programmable alarm verification, surge protection, RS-485 repeater connectivity, and integrated standby battery charging with polarity reversal and deep discharge protection. Key Features: Four Zone Conventional Detection: Supports 4 Class B initiating device circuits for smoke detectors and manual call points. Dual NAC Sounder Outputs: Includes two supervised notification appliance circuits rated for 0.6A per circuit. Form-C Relay Signaling: Provides dedicated relays for fire, fault, and supervisory event outputs. LCD and LED Annunciation: Equipped with a 16×2 dot matrix LCD and unambiguous colored LED indicators for system status. Integrated SMPS Power Supply: Operates on 110–220VAC with efficient low-current switched mode power design. Programmable Zone Configuration: Each zone can be set as alarm, supervisory, disabled, or walk test mode. Battery Protection and Charger Monitoring: Includes reversible polarity protection, low battery warning, and charger fault supervision. RS-485 Communication Option: Allows repeater panel connectivity for remote annunciation and monitoring. The RE-2554 delivers the reliability and precision required for conventional fire alarm detection and notification control in safety-critical building installations.
