Aritech DP2061N Addressable Optical Smoke Detector

1. Product Name: Aritech DP2061N Addressable Optical Smoke Detector

2. Description:

What Is the Aritech DP2061N Addressable Optical Smoke Detector?

Aritech DP2061N is an addressable optical smoke detector with a field-replaceable optical chamber, operating with the 2000 Series protocol. Its low-profile design, dual alarm LEDs providing 360° visibility and standard remote indicator output comply with EN54-7.

Operating Principle

The detector operates using the optical light-scattering principle: smoke particles entering the chamber scatter light, and this change is detected by the receiver. The measured value is communicated to the panel using the 2000 Series protocol. Sensitivity is configurable and an 5 alarm level can be set. When used with compatible Aritech panels, contamination levels are monitored, drift compensation is applied and a contamination warning is provided.

Role in Fire Detection Systems

An addressable optical smoke detector provides early fire detection by sensing smoke, which develops before flames appear. As each detector has its own address, the exact location of a fire is displayed on the panel when an alarm occurs. The advanced protocol, which includes CRC error checking and multi-bus loop codes, provides reliable operation without compromising communication speed.

Why Choose It?

• Replaceable optical chamber: During maintenance, only the chamber needs to be replaced; no special equipment or device replacement pool is required.
• Easy addressing: A straightforward numerical address from 1 to 128 is set using two rotary switches; no binary or hexadecimal conversion is required.
• Remote self-test: The result of an internal test started from the fire panel is reported back to the panel.
• 360° visibility: Dual alarm LEDs are visible from every direction.
• Standard base: All 2000 series detectors fit the same base and can be replaced easily.

Installation and Commissioning

DP2061N is ceiling-mounted by fitting it to an 2000 series detector base and is powered by the loop. Set the detector address using the two rotary switches before installation. Once the base wiring is complete, fit the detector into the base and add it to the system using automatic device discovery at the fire panel. Plan the layout so that the coverage area is below 80 m², and ensure the design complies with EN54 and local regulations. During commissioning, it is recommended that you carry out a self-test from the fire panel and a smoke test.

Frequently Asked Questions

What should I do if the optical chamber becomes dirty? The chamber can be replaced on site; there is no need to replace the entire detector or send it to a workshop.

How is the address set? Set a numerical address from 1 to 128 directly using the two rotary switches on the detector.

Which bases can it be used with? It is compatible with all 2000 series bases; DB2002, DB2004 and isolator-equipped DB2016 are the most common options.
