[4] Limitations Of Duct Detectors

WARNING

The National Fire Protection Association has established that DUCT DETECTORS MUST NOT BE USED AS A SUB- STITUTE FOR OPEN AREA DETECTOR PROTECTION as a means of providing life safety. Nor are they a substitute for early warning in a building’s regular fire detection system.

System Sensor supports this position and strongly recom- mends that the user read NFPA Standards 90A, 72, and 101. The DH400ACDCP Air Duct Smoke Detectors are listed per UL 268A.

WARNING

This device will not operate without electrical power. Frequently, fire situations may cause an interruption of power. The system safeguards should be discussed with your local fire protection specialist.

WARNING

This device does not sense smoke unless the ventilation system is operating.

CAUTION

For this detector to function properly, it MUST be installed according to the instructions in this manual. Furthermore, the detector MUST be protected from the elements and operated within ALL electrical and environmental specific- ations listed in this manual. Failure to comply with these requirements may prevent the detector from activating when smoke is present in the air duct.

DH400ACDCP specifications

The System Sensor DH400ACDCP is a cutting-edge addressable smoke and heat detector specifically designed for commercial and industrial applications. Its advanced detection capabilities ensure a high level of safety in various environments, making it an essential component of modern fire alarm systems.

One of the standout features of the DH400ACDCP is its dual-sensing technology. This device combines both smoke and heat detection in a single unit, allowing for a more comprehensive approach to fire safety. The smoke detection is performed using a photoelectric sensor, which effectively identifies smoldering fires that produce a large amount of smoke, while the heat detector is designed to respond to rapid temperature increases and fixed temperature thresholds. This dual functionality ensures early notification in the event of a fire, enabling timely response.

The DH400ACDCP also incorporates System Sensor’s innovative analytics technology. This feature utilizes advanced algorithms to minimize false alarms while maintaining sensitivity to actual fire threats. By analyzing environmental conditions and historical data, the detector can distinguish between normal activities and potential fire indicators, thus reducing unnecessary interruptions.

In terms of installation and maintenance, the DH400ACDCP is designed for ease of use. It features a robust addressable communication system, which allows for straightforward integration into existing fire alarm panels. The unit can be easily configured through the panel, providing flexibility in customizing notifications and response protocols. Its durable construction ensures reliability, while routine diagnostics capabilities help monitor device health and facilitate maintenance efforts.

Another significant characteristic of the DH400ACDCP is its compatibility with system monitoring and control platforms. The detector can report its status and any potential issues directly to centralized monitoring stations, enabling rapid response to emergencies or maintenance needs. By integrating with modern building management systems, the DH400ACDCP contributes to an overall intelligent safety infrastructure.

Overall, the System Sensor DH400ACDCP offers a cutting-edge solution for fire safety in various environments, combining advanced detection technology, ease of integration, and robust performance. With its focus on minimizing false alarms while ensuring reliable detection, the DH400ACDCP stands as a critical asset for maintaining safety in commercial and industrial spaces.
