The panel delivers a total power output of 2.5 amps and supports auxiliary output for low-power devices such as door holders. It includes dedicated alarm and trouble relays, an enhanced verification mode for distinguishing smoke detectors from manual stations, and accommodates two backup batteries (7.0 AH each). This unit is housed in a rugged metal cabinet and is ideal for applications requiring basic, reliable fire control functionality with minimal configuration. Key Features: Dual Class B Zones: Allows connection of up to two initiating device circuits for fire detection. Notification Appliance Circuits: Two output circuits rated at 2.5 amps total for driving horns, strobes, or other alarms. Auxiliary Power Output: Provides 0.5 amps max at 24 VDC to power accessories such as door holders. Dedicated Relays: Separate relays for alarm and trouble events ensure clear signaling and system monitoring. Enhanced Verification Mode: Distinguishes between smoke detectors and pull stations to reduce false alarms. Durable Cabinet Design: Rugged metal enclosure with space for two 7.0 AH standby batteries. Compact Form Factor: Efficiently sized for easy installation in tight spaces (14 × 12 × 3 in). Full Load AC Input: Operates on 120 or 230 Vrms at 60 or 50 Hz. Battery Charging Support: Supports 27.0 to 27.6 V charging with 750 mA maximum current. Reliable Power Monitoring: Detects low battery at 20.4 V and low AC at 100 Vrms (full load). The SK-2224 is a dependable fire control solution for small buildings, supporting core alarm functions with minimal maintenance requirements.
