Optical smoke detector SATEL DRP-400 addressable model 38928 for fire detection, compatible with addressable loops

The SATEL DRP-400 optical addressable smoke detector (model 38928) is designed for integration into addressable fire alarm loops to provide early detection of visible smoke. The detector uses an optical sensor to identify smoke particles and supplies a unique address on the loop for precise location reporting. Its compact design and compatibility with standard addressable systems make it suitable for both commercial and residential installations where centralized monitoring and rapid fault identification are required.

Advantages

The optical sensing chamber improves sensitivity to visible combustion products while reducing false alarms from dust and airborne contaminants. Addressability allows individual identification of the detector on the fire alarm loop, simplifying maintenance and troubleshooting. The detector is built to work with compatible addressable panels, enabling centralized status reporting and faster emergency response. Its form factor supports discreet mounting on ceilings or walls without obstructing interior design.

Suitable for

• Office buildings and commercial premises
• Residential blocks and apartment complexes
• Retail stores and shopping areas
• Storage rooms and light industrial spaces
• Integration into addressable fire alarm loops for centralized monitoring

Key specifications

• Detection principle: optical smoke detection
• Addressable: supports individual addressing on compatible loops
• Mounting: ceiling or wall installation
• Compatibility: designed for use with addressable fire alarm control panels that support detector addressing
• Physical design: compact housing for unobtrusive placement

How to use

Install the detector according to the fire alarm system manufacturer’s instructions and wiring diagrams. Assign a unique address for each detector during system configuration so the control panel can identify the detector’s location. Mount the detector on the ceiling or wall in the recommended position for the protected area, ensuring unobstructed airflow to the sensing chamber. After wiring and addressing, perform commissioning tests via the control panel to verify detection thresholds, communication, and alarm reporting.

Recommendations

Place detectors away from sources of dust, steam, or strong air currents that could affect optical sensing. Follow regular maintenance schedules: clean the detector housing and test communication with the control panel periodically. Use detector placement and spacing guidelines from relevant fire safety standards and the control panel manufacturer to ensure reliable coverage.
