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.
