Aritech DP2061T Addressable Multisensor Detector (Optical-Heat)

1. Product Name: Aritech DP2061T Addressable Multi-Sensor Detector (Optical-Heat)

2. Description:

What Is the Aritech DP2061T Addressable Multi-Sensor Detector?

The Aritech DP2061T is an 2000 series addressable multi-sensor detector that combines the sensitivity of optical smoke detection with heat detection. With five operating modes programmable from the fire panel, one device can adapt to different risks and operating conditions.

Operating Principle

The detector combines optical light-scattering detection with heat measurement. Depending on the mode selected at the fire panel, it can operate as a heat-supported multi-sensor with one of two smoke sensitivities, as a dual sensor with independent optical and A2R heat sensors, as an optical-only detector (EN54-7), or as an A2R heat-only detector (60°C, rapid temperature rise). Modes can be changed dynamically using day/night programming for each sensor.

Role in Fire Detection Systems

In areas where occupancy varies throughout the day, a single detector type can help reduce the risk of false alarms while maintaining early detection. For example, it can operate as a heat detector during the day when a building is occupied, then switch to a high-sensitivity smoke and heat mode at night when it is empty. The CRC error-checked 2000 series protocol ensures reliable communication with the fire panel.

Why Choose It?

• 5 operating modes: Modes programmed at the fire panel allow the detector to adapt to different risks.
• Day/night control: Each sensor is managed independently according to the building's occupancy status.
• Replaceable optical block: The chamber can be cleaned or replaced on site, with no recalibration required.
• Smart maintenance: Compatible fire panels provide self-test, drift compensation and contamination alerts.
• Easy addressing: A numerical address from 1 to 128 is set using two rotary switches.

Installation and Commissioning

DP2061T is ceiling-mounted by fitting it to an 2000 series detector base and is powered by the loop. Set the address using the two rotary switches, then fit the detector into the base and register it at the fire panel. Configure the operating mode and day/night schedule at the fire panel. Plan the layout so that the coverage area is below 80 m² and complies with EN54 and local regulations. During commissioning, it is recommended that you carry out a smoke or heat test appropriate to the selected mode.

Frequently Asked Questions

Which modes does the DP2061T support? It can operate in two smoke-sensitivity multi-sensor modes, independent optical and heat modes, optical-only mode, and A2R heat-only mode.

How is the mode changed? Modes are programmed at the fire alarm control panel and can be changed automatically using a day/night schedule.

How is the optical chamber maintained? The optical block can be replaced on site; no recalibration is required after cleaning.
