Information About 4100-1289
The 4100-1289 is a dedicated LED and switch controller board within the Simplex 4100ES/4100U fire alarm system series. It integrates seamlessly with the 4100-1288 mounting assembly to expand panel functionality by providing additional annunciation and operator control. This module enables efficient monitoring and control of site-specific functions using tactile, alternate-action switches and high-efficiency LED indicators. It is compatible with Simplex fire alarm cabinets, supports programmable input/output customization, and is optimized for reliable performance in fire safety system environments.
Key Features:
- LED Expansion Capacity: Supports control of 64 LEDs, each with 2.5 mA nominal current draw, for clear visual annunciation.
- Switch Control Functions: Provides 64 alternate-action ON/OFF switches for user interaction and system input.
- Compact Integration: Mounts directly to the extra space of the 4100-1288 without requiring an additional mounting plate.
- Flexible Input Options: 24-point I/O module selectable for different switch types and supervision levels.
- Output Customization: LEDs can be configured for steady-on or pulsed output to drive connected relays, lamps, or indicators.
- Clear Visibility: High-efficiency LEDs remain easily visible through the cabinet glass door for quick status identification.
- Programmable Functions: LED behaviors, switch inputs, and printer outputs are fully configurable through CPU customization.
- Efficient Power Use: Operates at 19–33 VDC with a maximum current of 212 mA at full LED load.
- Modular Expansion: Supports up to two controller boards per bay, offering scalable control within 4100ES/4100U panels.
- Ease of Labeling: Slide-in local labels provide precise identification of LED and switch assignments for operators.
The 4100-1289 delivers the reliability and precision required for advanced annunciation and operator control in modern fire alarm systems.
