Information About MIX-2251AP
The MIX-2251AP is part of Mircom’s Advanced Protocol intelligent detector series, providing precise addressability and faster system response. Using a photoelectronic optical chamber, it detects smoke from a broad range of combustion sources while minimizing nuisance alarms. Its Advanced Protocol communication supports up to 318 devices per SLC circuit, while backward compatibility allows operation in CLIP mode for legacy systems. With features such as dual LED indication, magnetic testing, and chamber contamination reporting, it enhances both operational reliability and maintenance efficiency.
Key Features:
- Advanced detection technology: Photoelectronic optical chamber identifies smoke across multiple fire types.
- High system capacity: Supports up to 318 devices per SLC circuit with Advanced Protocol.
- Backward compatibility: Operates in both Advanced Protocol and CLIP mode for flexible system use.
- Addressable configuration: Rotary switches allow direct-dial entry of unique addresses.
- Real-time sensitivity monitoring: Detector sensitivity is continuously tracked and programmable at the control panel.
- Dual LED indicators: Provide clear communication and alarm status, with steady activation during alarm conditions.
- Maintenance efficiency: Point ID capability allows identification of exact detectors for service when contamination is detected.
- Environmental protection: Unit is sealed against dust, insects, and back pressure to maintain accuracy.
- Simplified testing: Built-in magnetic test feature allows functional checks without removing the detector.
- Durable design: Compact 2-inch profile with interchangeable low-profile base options.
The MIX-2251AP delivers the reliability and precision required for intelligent fire detection and efficient maintenance in commercial and industrial applications.
