DH100ACDCLP specifications

The System Sensor DH100ACDCLP is a cutting-edge addressable heat detector renowned for its advanced features and reliability in fire safety systems. Designed to meet various application requirements, this device excels in environments prone to false alarms while ensuring efficient fire detection.

One of the DH100ACDCLP’s main features is its advanced thermal sensing technology. This device utilizes a combination of fixed temperature and rate-of-rise sensing methods, allowing it to accurately detect abnormal heat levels in its surroundings. The fixed temperature feature triggers an alarm when the ambient temperature exceeds a predetermined threshold. Meanwhile, the rate-of-rise detection monitors rapid temperature increases, making it ideal for applications like kitchens, attics, and mechanical rooms where combustibles may not be immediately visible.

The DH100ACDCLP also incorporates an innovative addressable technology. This allows the device to communicate directly with the fire alarm control panel, providing precise location information and reducing response times during emergencies. By having each detector uniquely identified, facility managers can easily pinpoint which unit has triggered an alarm, streamlining response and ensuring the right areas are addressed swiftly.

Another notable characteristic of the DH100ACDCLP is its robust design, capable of operating in a variety of challenging environments. The unit is built to withstand temperatures ranging from -40°F to 150°F (-40°C to 66°C), making it suitable for both indoor and outdoor installations. Its resilient construction ensures longevity and durability, which is crucial for maintaining reliable fire safety measures over time.

Moreover, the DH100ACDCLP is compliant with various safety and performance standards. It obtained listings from UL and other recognized certification bodies, ensuring it meets strict criteria for fire detection capabilities. This compliance reinforces its credibility and effectiveness in safeguarding lives and property.

In addition to its technical features, the DH100ACDCLP is designed for straightforward installation and maintenance. Its user-friendly interface allows both installers and end-users to navigate settings and conduct routine checks with ease, ensuring that the system remains functional and reliable.

In summary, the System Sensor DH100ACDCLP stands out as a sophisticated heat detector, combining innovative thermal sensing technologies with an addressable communication system. This ensures precise detection, rapid response, and adaptability to various environments, all while maintaining compliance with safety standards. It is an indispensable component of modern fire detection systems, providing peace of mind to property owners and facility managers alike.
