Information About SK-5204
The SK-5204 replacement board is designed for use in Silent Knight 5204 conventional fire alarm control panels, providing the main system logic, power distribution, and control circuitry for four detection zones. It supports both 2-wire and 4-wire smoke detectors, offering flexibility in system design and upgrades. The board includes two supervised notification appliance circuits (NACs) rated at 1.5 amps each, supplying a total of 3 amps of power for horns, strobes, and other signaling devices. When paired with the optional 5205 Digital Communicator, the system can report alarms and supervisory conditions to a central monitoring station. This replacement board ensures continued reliable performance of legacy 5204 systems in commercial or institutional fire alarm installations.
Key Features
- Four Detection Zones: Supports up to four conventional input zones for flexible system configuration.
- Dual Supervised NAC Circuits: Provides two 1.5A outputs for horns and strobes, ensuring signal supervision and reliability.
- High Output Capacity: Delivers a total of 3A for powering external devices such as annunciators or notification appliances.
- Detector Compatibility: Works with both 2-wire and 4-wire smoke detectors for broad system integration.
- Optional Digital Communication: Interfaces with the 5205 communicator for remote monitoring via central stations.
- Easy Replacement Design: Direct plug-in replacement for existing SK-5204 panels without requiring rewiring.
- Full Circuit Supervision: Monitors inputs and outputs for trouble conditions, maintaining NFPA compliance.
- Durable Construction: Engineered for long-term reliability in commercial fire protection environments.
The SK-5204 delivers the reliability and precision required for maintaining operational fire alarm systems with robust power output, flexible detection compatibility, and optional remote communication.
